First, I confess I have a 91 Metro with front and rear bars.

While everyone talks about clearing the front bar, I've found the rear bar is the nightmare.

I'm guessing a Swift GT intermediate pipe and muffler would fit properly however it seems that only the muffler is still available.

I have no idea if the 95+ Metro pipe would clear properly.
And then there is the Bosal exhaust - again no idea. (one might speculate that if you can clear the bar, it would also fit a car w/o the bar - so make one exhaust that clears the bar???)

So what do people do?

(The only way I could get things to clear was tie the rear of the muffler up as high as the hanger would go and splice a 22 deg patch pipe between the muffler and intermediate pipe. It is not perfect, it does rattle, and looks like hell.)

NOTE: I wonder if the GT muffler has a higher inlet which would help tons?

Don't waste your time and money trying to hunt down oem exhaust pieces. Take it to a muffler shop and get one custom made

I have an aversion for muffler shops. I really hate when those muffler shops say they couldn't save the muffler when it is 1 year old and they are too lazy to take the o-a torch out to save it.

Of course if they can bend one up out of 16ga - well that would be quite the thing!

I do tons of welding and have welded up custom exhaust systems although I confess that I make miter saw bends.

EDIT:

I'm trying to find someone who has tried the 95+ intermediate pipe which is from cars with rear sway bars. I'm guessing they might fit on an 89-94.

Pipes are $25 to $45 and the muffler shop wants $100 w/o any muffler or resonator.

I use a Bosal GTi catback and test fitted a rear swaybar once and they didn't touch. I think the Bosal is a pretty good deal. The only difference is in the muffler, a 1.0 has only one tailpipe, where the GTi has two. I love the darker sound it makes on mine. The previous one lasted four years and only cost me 120 euro. A (stainless) custom catback would set me back more than 500 euro (stuff like that is expensive here in the Netherlands) and I didn't have the cash at the time. Just to be clear, my signature says mine is a 95, but keep in mind that it's a european one, so it's the same as a 91-94. They sold them up to 2004 here.

Good to know about the Bosal - no reason to make an exhaust that would not accommodate a rear sway bar.

As far as getting something bent up at a muffler shop, I would only do this if I was going to run bigger pipe like 1.75 or 2.0 diameter. In that case, the extra cost of the custom bending would at least get you something for your money. (I did drive a Metro with a "fart can" in the back and I was impressed with the extra midrange torque it had. However a farty sounding little car makes my flesh crawl!)

Right now, RockAuto has the GTi muffler for $60 and it appears there is a $50 Walker rebate for it. I was thinking of maybe using this muffler on my 91 Metro 5-door but not sure if the dual tailpipes would interfere with the bumper (which is notced for a single tailpipe.)

I've got a good flanged resonator and muffler. RA has the 2-dr pipe for something like $26 shipped. No doubt the Low Buck solution and probably the sensible one for now. If my CAT pipe goes bad, that's another story.

Mine has around 3 cm room until i hits the bumper, I think you'll be safe, even if the tailpipes are bigger.

if I remember right the earlier TURBO cars (89 and up)and gti's had a small hump in the pipe to clear the sway bars. non-turbo cars did not have that hump in the pipe.
my gti has custom exhaust, they bent the pipe to clear sway bar and underbody brace.
pipe is cheap, but you pay good money for a good muffler.

'oid, are you really sure about that?

the reason i ask is that the rusted out 89 turbo firefly i bought in ottawa for parts for my first turbo3 vert transplant had the rear sway bar hanging off the trunk floor where the factory mounts had rusted away. it had the same saddle type mounts i subsequently found on swift gt cars.

on the exhaust pipe to clear the rear sway bar, the rear pipe for the gt has the little bend in it that clears the sway bar tip and end link.

i prefer to have the pipes bent at an exhaust shop. on a couple of cars i had to have that pipe fabricated more than once. using springs that lower the car makes that shot even tighter as the tips of the sway bar move upwards.

still, i have used 2.5" diameter pipe on lowered cars and have always been able to finagle enough clearance to keep the pipe from rattling on the end link. i engineered and fabricated the progressive diameter exhaust on my blue monster turbo3 using 2", 2.25", and 2.5" pipes on a lowered vert with a bunch of custom braces and succeeded in de-rattling the exhaust system.

it helps to use mounts that limit the movement of the pipe better than the usually clapped out oem rubber donut type hangers. :wink:

all the turbo cars I have owned had rear sway bars.
2.5 inch pipe clears no problem, have that size on my t3 and gti. just get it bent properly, there should be no issues.

"ap" brand exhaust will not clear the sway bar, I've used it from a local supplier and it's no good.

I just checked my bone-stock 1990 Sprint Turbo. It has factory front and rear sway bars. It uses the identical rear twin tip muffler and intermediate pipe (rear of the resonator) as the GTi.
