My uncle is putting a rebuilt L67 into his Grand Prix and has talked about the extra 48" or so of exhaust that our cars have. I'm not sure if he's going to go through with his plan, but he wants to route ~48" extra of exhaust piping. Should sound pretty cool if he can find a way to do it.

Pretty cool that our Aussie friends across the pond are tinkering with L67s just like we are!

Just listening to those cars exhaust through my computer's sound system (speakers and a sub woofer) made everything around it rattle, probably just like the vibrations felt inside the car. Not what I'm looking for. But I'm always on the hunt for something to eventually replace the stock exhaust besides what I've already replaced.
All I have is the SS Headers with a high flow Cat to a stock exhaust.
But as the stock mufflers have aged there is a better sound coming from them, just would like to enhance that sound without a lot of resonance in the cab.
Don't know if that's possible. So in the meantime I'll live with what I got.

Its a mandrel bent seamless donut. Never mind it needs to be cut to use, but how could such a thing be made?

My guess is they are spun in halves, then welded together and finished on a lathe. For the price they are asking, it would allow multiple processes.

Well, after a 4 day extravaganza, I fixed up my exhaust.    

My previous setup was made with alumnized steel, and really didn't stand up to the test of time at all.
rivperformance.editboard.com/t7396-write-up-custom-y-split-exhaust-pipes

So I figured I'd better re-do it in 16 gauge 409 stainless.  Bleh, what an ordeal that was.  Normally you run a "purge" of argon into the pipe for stainless, but at over a dollar a pound argon gets expensive to do this.  Add to this that the regulator wasn't really functioning properly, I mutilated the inlets on the mufflers removing the old pipes, and that welding new stainless to old stainless(I wanted to keep the old mufflers) is a bitch; it didn't turn out with the greatest welds.  Its solid, and no leaks, but what a hassle.  Anyway, enough with the excuses, here's what pics I got:

FAQ: The Exhaust Thread - Page 38 20150526_225950
I assure you, the fact that the above kind of resembles a set of ovaries is no reflection of the car itself. smile   Two mounting points on each muffler, a bracket that ties into the existing rubber hangers, and another universal muffler hanger welded on and hangs nicely from one of the bumper support bolts. 2.25" all the way out.

FAQ: The Exhaust Thread - Page 38 20150526_225857

Ignore the mess, note the old falling apart Y pipe, complete with leftover pipe-clamps and beer cans to keep it together at the bottom right.

FAQ: The Exhaust Thread - Page 38 20150527_001049

And hung on the car. Fits nice and snug, miles more clearance than before. Eventually I might try the "J pipe" concept in under the spare, but this was such a pain I didn't get to it.  Interestingly enough, the new setup behaves differently anyway.  I used to get a bit of drone and buzz @ 2000RPM, but now its gone.  Its got a very nice resonance/rumble now @ 2800+ RPM, and of course a growl and bellow at WOT when the flaps are fully open.  Its interesting how type, gauge of pipe and changes in routing can make such a difference with the exact same mufflers.  Overall, I'm VERY happy with how it sounds.  I'll get a few better pics later and see about some vids.

Vids of above exhaust.  Hard to capture exhaust sound, especially with a cell phone and with the compression when uploaded.  I need a bumper mounted gopro.

Typical idling vid:

sounds like a 3800 idling.

Typical reving vid:

I know reving in neutral doesn't tell you anything.

Outside, driving, part throttle and off:


I don't know why this one is sideways, various inside noises with their RPMs:


Normal driving use. The rumble heard inside is the same as outside, just louder out the back:


More fun bit, starts roughly half way in:

Will do Matt, I saw ur review on the zzp website. Thanks for the heads up, I already marked the holes using the oem downpipe. Will the lead donut gasket seal it up good or should I also use the 97+ flat gasket?

I reused the 96 gasket but it leaks. You can try the 97 gasket and see if it fits, if it does I might swap mine out for a 97+ style. Orange RTV is your friend. You can also just try a fresh donut gasket and see how well it works out. It's pretty finnicky.

They're actually a bit smaller than stock but have 2.5" pipes. I scored them for a song and have access to a welder and any pipes I'll need, so why not? I figure they'll sound and look pretty much exactly like the ZZP setup for GPS.

cool cool, i"m sure they just look big in the trunk with the pipes in the. also the thought of them on a tractor seemed funny. are they stainless?

The tips are mostly stainless with the back part left alone so that they can be welded to the regular (possibly galvanized?) steel. The mufflers are a bit taller than stock but there's plenty of room to stuff them up in there.

would a 3" exhaust cutout make gains if you have 320-350WHP or is more power needed to see gains with a cut out?

seeing some awesome numbers on the web both those guys are starting with 4-450whp turbos.

This is the magnaflow 2.5 inch t pipe I ordered.

Needed to get this reducer to go from 3 inch to 2.5 smoothly. Link to reducer

FAQ: The Exhaust Thread - Page 38 _1_110

Took my parts to a iron worker shop to get welded. I ended up cutting off the original hangers that go in the middle before the split and got them welded in the same spot.

FAQ: The Exhaust Thread - Page 38 Img_2013

I ordered 2 of these 90° bends on eBay Link to 90° bend
FAQ: The Exhaust Thread - Page 38 Kgrhqz10

Other than that I just needed some u clamps, exhaust hangers from O'Reillys and I ordered some 3 inch band clamps from summit. ZZP stainless resonator and mufflers along with 3 inch dp.the bends worked great, they were the perfect length. The only other thing I almost failed to mention is that I had to bang the floor in where that curve in the OEM muffler is. A lil sledge hammer and clear safety glasses did the trick. This allows you to run a straight length about 4 feet of 3 inch pipe after the ZZPerformance stainless steel resonator instead of putting that curve there. I'm sure you guys have done this before
