injected and exhausted

[gadget73]

New injectors and exhaust installed over the weekend. Yay. I now have 2.5" dual exhaust with only one wrinkle bend in the whole system: the little downturns on the tips. Mustang X pipe, Hedman Hedders, MAC flow tubes, Impala SS tailpipes and cheapie Summit turbo mufflers. Its not excessively loud, no drone (which I'm more than a little impressed with) and the fitment is quite nice. My only concern are the 2 pieces of extension pipe I got from Advance. I might see about getting some high temp paint and protecting them since I doubt its great quality metal. Now that the cosmoline has cooked off, I can actually get paint to stick. The injectors took care of an off-idle stumble/hesitation problem that I've had for a while and between them and the exhaust, it really boogies now. I'll have to get the pics uploaded somewhere, but once I do, there will be pictorial proof that Chevy parts work on a Ford product.

Nice...now you should have a substancial amounnt of power with the HO setup and the exhaust huh.

What did your exhaust system cost about (without the headers)? I remember you recomending the ss tailpipes to me before and I am interested.

[lairdt]

You have a partlist with part#'s? Looking to do this myself on my '89 which should be the same layout.

Remember a thread a while back asking if it SS pipes would work - glad to see it did. How much modification it take?

[Four Eyed Stangs]

Awesome!

I have all the parts waiting for me to do my exhaust.

I lost my keys a couple days ago so I am spending time and money re-keying both cars first!

The TC is done and running as of today. I lucked out with it. The old worn out ign lock turned with the wrong key. This made getting the lock cyl out a snap!

The Mustang can wait until next weekend.

[CobraConti]

how do you like those Summit turbos? Are those the $15 ones? I'm thinking of getting pair for the Conti.

WAY-TO-GO Gadget !

Dying to see the Impala tailpipes on ! Any interference problems with the tailpipes ? Did you use the end tips too ? Did the ground clearance get reduced ?

[gadget73]

Well, the thing is I have to get the pics from my friend. He took a few and they're on his camera.

v8_dave:
Headers $150
X-pipe w/ 2 nearly new O2 sensors $175
Mustang flow tubes $50
2 mufflers $30
pair tails $80
misc extension pipes, nuts, bolts, clamps, hangers, $70 ?

lairdt:
tailpipes WLK-54017 and WLK-54016
headers: HED-88600 (any mustang 5.0 shorty for 86-93 works fine)
mids: 43800 (unknown if this is a standard part number. any mustang flow tube works, these are MAC brand because it was all I could find in stock anywhere)
mufflers: SUM-630225. Any 2.5" offset/offset muffler is suitable. Case can be longer than 18" if you like, jsut customize the length of the extensions on the midpipes to match.
You'll also need any standard issue Mustang H or X pipe as well as a few lengths of straight extension piping. One extension between the ends of the flow tubes and the mufflers, and optionally another piece at the end of the tailpipes to put the tips in the right location. The Impy tails will end behind the rear tire under the rear quarter panel. There is also room in here for an 18" glasspack and a downturn if you'd like some extra baffling, or you can use whatever tips you'd like.

CobraConti: I'm satisfied. Not loud, and the fitment was OK. They're nice for a $15 muffler, and I was expecting something louder. To my pleasent surprise, they are not annoying, but it still has a bit of sound to it. I imagine in a few years they'll go away, the metal looks kinda thin but for the price I think they're pretty decent.

Sixlitre: no interference at all. It looks like they were meant to be there. It took the standard tweaking and adjusting to get the pipe and mufflers clocked just right so they sat properly, but thats with anything. I didn't use Impala tips, just a standard straight extension pipe whacked to about 15-16" and a downturn tip, standard fare stuff you can find at Autozone, etc. You actually can't even see the tips under the bumper unless you get level with the car. No unsightly pipes hanging under the car. No ground clearance issues I don't think. It might sit about 1/2 - 1" lower right at the junction of the X pipe to the mid pipes, but its not low enough to cause any issues. It seems Mustang engines sit on the frame slightly cocked relative to the engine fitment in a Panther since the H and X pipes are slightly lower on the driver's side vs the passenger side. The H on the 85 Crown Vic my friend is doing an engine swap in sits that way, as does the Bassani X on the "SuperLinc" project car.

[v8_dave]

NICE! $80 for tails, $30 for mufflers, $40 for an X pipe on ebay, $20 for extensions, and welding is free... $170-$200 for a 2.5" exhaust? Im thinking about it. ;)

:ahoy:
Any pics?

Pictures!

First two are of my steering box swap for 2vmodular. The pics aren't so great. Its kinda hard getting pictures of pipes under a car when its not up in the air. The picture of the back is misleading. My car does not sit wierdly crooked, its just the angle of the picture. I had the camera just about sitting on the ground for that shot and it wasn't quite level.

I might see about getting the pipes welded at some point. It was clamped because I can't weld, and the welder my friend has needs different wire. Whatever he's got in there now doesn't work very well and it spits and sputters too much to make a clean weld.

[v8_dave]

hmmm so the impala tails are alittle short then, but no clearance problems witht the axle? Does the exhaust steam still come out nicely from the back of the car or get trapped under it? But all else looks good!

You dont need to weld them; I think it just cleans up the look and saves on clamp money. but it is also a PITA to weld under the car at points. I found mine in the local classifieds for $40. It spat too but I switched the pos/neg terminal b/c I am using flux core wire at now its great.

Nice, your ebrake cable (right?) Is looking about the same as mine, they say if you dont use it montly, dont use it at all

[gadget73]

Mine works but I seldom use it. I check it from time to time though. The rubber sleeve thats supposed to hang on it to keep it off the floorpan is gone, and there is a groove in the floorpan where it rubs.


Yes, Impy tails are a bit short. They take care of the over-axle portion and leave plenty of room to do whatever you like with tips. No clearance issues on the axle or with the suspension in the back. They aren't a drop-in replacement for stock tails but adding a piece of straight pipe is quite simple. The bending for the over-axle part is the tricky bit, especially since most shops aren't outfitted to handle mandrel bends on 2.5" pipe. The only wrinkle bends on the whole system are the tips themselves. The rest of it is nice and smooth.

Hm, you know I'm not sure about the steam, I honestly haven't looked that close. I'd not have been upset if those pipes ended up about 1/2 - 3/4" lower at the tip, but I can always replace the tips later with slightly longer ones if I want. I might switch these out for some simple chrome ones that look pretty much like what I have now but thats about it. I didn't want big exhaust pipes sticking out the back, just a nicely hidden exhaust.

V-8 Dave just put me onto this thread

I'd been waiting to see these pics. Looks great ! Looks like this is all I need to complete mt exhaust the way I want it !

Gonna come off the 3" single cat with a reducer to 2 1/2" then pipe it to a 2 1/2" generic (quiet muffler) that'll fit and be clocked the way I need it.

Then one of your Impala SS tailpipes (from Dynomax) will be 2 1/2" of mandrel bent clearance over the axle. After that I'll use another reducer, to increase back up to 3" so I can slap on a nice 3" pipe with a turn down, just up a bit outta sight, like you did.

Here's a shot I got off the net of the underside of a CV with the Impala tailpipes (they used resonators too);

Thanks again

The pipes on the Superlincoln are made much like this with the resonator in the back. Whats actually on that for resonators is a cheap short glasspack. It makes a difference in sound level and adds no extra restriction.

[Ivan D.]

Malcolm, do not increase the tail pipes to 3" diameter after the Implalla SS pipes, that will slow down the exhaust gases (and you want to keep the velocity up), keep the 2.5" diameter and add a turndown to that.

Really Ivan ?

Even though it's only the last 24" ??

I did it with the last 18" of my Bronco's mandrel bent 2 1/2" Dynomax tailpipe;

http://www.supermotors.net/getfile/115460/fullsize/picture-022.jpg (http://www.supermotors.net/vehicles/registry/media/115460_1)

I hated the Jeep Grand Cherokee-ish tailpipe end (right in pic) so I cut it off(after the axle), welded a 2 1/2" to 3" reducer and then just 18" of 3" straight pipe.

I'll take it under advisement as it'll be easier finding 2 1/2" straight pipe with a turn down, like I want it.

[Ivan D.]

Actually you're right, 2ft of 3" piping at the very end of the system probably wouldn't do that much of a difference to the exhaust velocity. Now that I'm thinking of it many trucks have that setup, last foot or so of the exhaust upped to 3.5" or 4" straight pipe.

My exhaust has the increase of diameter at the very very end, and only cause of the dual 3" outlet tips I'm using, I was thinking of doing it all in 2.5" piping but with my pretty much see-through design I'd kiss goodbye to the velosity and backpressure so the idea was scrapped.

That's a relief

I'm really only doing the 3" turn down, for the last 24", due to vanity (like anyone's gonna notice).

With the Impala tailpipe it offers the opportunity as you have to add "something" to make up the last 24".

My headpipes off the manifolds are fully 2 1/4" each;

http://www.supermotors.net/getfile/246250/fullsize/img_0121.jpg (http://www.supermotors.net/vehicles/registry/media/246250_1)

Running into that flow and torque producing Flowmaster scavenger "Y" connection and exiting at 3";

http://www.supermotors.net/getfile/246243/fullsize/img_0076.jpg (http://www.supermotors.net/vehicles/registry/media/246243_1)

From there it's through the 3" cat;

http://www.supermotors.net/getfile/246248/fullsize/img_0106.jpg (http://www.supermotors.net/vehicles/registry/media/246248_1)

Then I'm necked back down to not the stock 2", but a not much better 2 1/4" connecting pipe into a 2 1/4" GMC truck muffler (still whisper quiet though);

http://www.supermotors.net/getfile/247787/fullsize/img_0001.jpg (http://www.supermotors.net/vehicles/registry/media/247787_1)

That muffler exits at 2" enabling the only option I knew of then, the stock crimped to death 2" Lincoln tailpipe;

http://www.supermotors.net/getfile/247789/fullsize/img_0005.jpg (http://www.supermotors.net/vehicles/registry/media/247789_1)

NOW HOWEVER, thanks to Gadget's pioneering I hope to come off the 3" collector flange, on the back of the 3" cat with a streamlined reducer to 2 1/2". Imagine the reducer sliced off where my thumb is;

http://www.supermotors.net/getfile/244967/fullsize/img_0023.jpg (http://www.supermotors.net/vehicles/registry/media/244967_1)

From there it's 2 1/2" pipe all the way into a (hopefully) quiet 2 1/2" In and OUT muffler.

Then the Dynomax mandrel bent right 2 1/2" tailpipe. After that I may go with a 2 1/2" or 3" run of straight pipe into a turn down(NOT in chrome).

True a full 2 1/2" muffler isn't that much of an improvement over the 2 1/4" IN and 2" OUT muffler I have, BUT ! the 2 1/2" mandrel bent Dynomax Impala SS tailpipe sure will be !

Thanks for all the help and advice guys !

Good job and good luck. Ill post pics of my setup tonight after I work in it this afternoon.

[mjkandelj]

Can ya'll help me on where i can find a set of headers for my '94 Lincoln Mark VIII? Will i have to buy mustang headers because it seems like no one manufactures 94 mark VIII headers.
Give me a lil info on it, please, Thank you guys!
