So I didn't like the idea of having the long tubular sides pipes on a third gen. I think it would look pretty bad, but I still wanted to do something with side pipes. So this is what I've got to put on my 86 Z28. I'm a fan of loud and obnoxious so I went with cherry bombs, crossover and the tips. (all in 3"). I want to run them out each side in front of the rear tires. I want to tuck the tips in under the car to where mostly the 45 in sticking out lining up the the sides of the car. I anticipated clearance issues so I've already been on "suspension" and gathered some info on getting an inch or so of lift in the rear. what do you think?

 

The car will look a LOT better 1.5 inches lower than jacked up in the rear to make room for exhaust piping. But to each his own I guess... There is just no room under the car for something like that to be "hidden". It will just look like huge pipes under the car which is way too high in the air.

It's not that hard to run a big single pipe down the driveshaft tunnel.

 

I'm not necessarily trying to the big diameter piping, nothing else on it stock so I figured I might as well have fun with this one. I've been up under mine a couple of times and don't quit remember how much space I have have under there. I've got a carbed intake so I wanted it to be able to breath well.

 

Then I reiterate, there's plenty of room going through the stock exhaust routing for a nice 3 inch single exhaust. Or if you want to really fabricate something make yourself a custom crossmember and run a long tube+y-pipe arrangement down the driveshaft tunnel.

Anything that goes out the side of the car will be extremely visible under the car.

 

I think your best bet will be to run the x-pipe and glasspacks along the driveshaft tunnel, then to a 90* elbow on each side into oval tube to run to your tips. 3" for each side will be overkill, stepping down to 2.5" will help keep ground clearance without having to jack up the rear. Although you will probably want to switch to an oval or rectangular tip to do this.

 

IF you insist on doing some sort of side exit... Which has absolutely NOTHING to do with the engine breathing well. Some shorty headers and a 3 inch exhaust is good for 450-500hp and will allow you to lower the car which will give it a much meaner look than exhaust pipes out the side of it.

IF you insist... do this:





You can put a muffler where the cat used to go.

If you do it the "Easy" and "obvious" way... it ends up looking like this

 

its pretty hard to pull off a good looking side exhaust.

 

Wrong. Besides askulte's side exit, it's impossible on a thirdgen. These are not side pipe or side exit cars. It simply doesn't work.

 

agreed.

 

Thanks for the ideas, but I think It will pull it off. I'll have to do some tinkering with it I'm sure.

 

I notched the left side under the drivers side brace in the wheel well, so that it was similar to the passenger side. I used flow master hp 2 mufflers and tucked the exhaust up close to the floor. Then I brought the tip out on a 45 right in front of the trailing arm mounts and tip is even with the side skirt. For the most part I don't have much ground clearance, I only bottom out on speed bumps.

 

So you cut up the frame, have no ground clearance, and you cant run subframe connectors?

Sounds awesome.

If you did it with low profile tips it would make a little more sense (like boomtubes), but not being able to use subframe connectors is a big downer.

 

Rectangular low profile tips is the only way to have a chance at it looking good

 

I modified a non structural part of the body and I have weld in sub frame connectors. Its just as strong as the passenger side stock routing. At the tip I have 4 or 5 inches of clearance, Not any different as people slamming their cars.

 

I did it but only had 1 side pipe, on the right side, cherry bomb in that valley down the side [ I run Alstons SFC, they don't take up that space] but problem I had was a 90* turn out really killed high end power, had to knock a hole in the turn to let it breath.

soon got annoying sound wise..... still there, but runs fully out the back.

 

Side pipes on a thirdgen just end up looking *******. If you like it, do it. Its your car.

But be prepared for the ******* comments.

Personally, I would do a Willie's style dual exhaust before side-pipes. Twin 2.5" pipes following the stock single tube exhaust routing. You keep the ground clearance and you get the true dual sound.

Though a good single 3" would probably flow just as well and be simpler to route.

 

I have dual 2.5" side pipes, or side exit, whatever you wish to call em. I dont have any ground clearance issues. The "frame" rails hang lower than my pipes do. the tips are angled towards where the tires meet the ground but stay tucked under the car. They're simple effective and cost me less than a case of beer. Wouldn't want em on a DD, but I wouldn't DD a V8 camaro either, fuel is almost $4 a gallon. :P

 

Well I am a glutton for punishment. I have two camaro's (83 Z with LT1/T56, 2012 2SS camaro) and a 2011 Laramie 3500 with a cummins and long bed. Both camaros get hte same mileage at about 24/25 on the highway and 18/19ish around town depending on how I drive. The truck does better than both at 24 on the freeway and 20/21 around town (tuner and 5" TBE).

But I digress, I would love to make a nice side exit that would go along both sides but I just dont see the benefit other than looks and the amount of work to put into it to make it look good, be functional, and not drag every bump you come to. I already drag my exhaust on big speed bumps where the cat goes (no cat on mine, thanks TX!) so I can only imagine the road selection that would come from hanging exhaust.

 

Im not sure I really see the benefit here, but that is really nicely packaged. Are you able to run sfc's?

 

Any power gains over a full exhaust of equal sisze would be debatable, tho they are leaps and bounds better than the OE 2.8 exhaust that was still with the car. That said, performance was a factor in choosing to do it this way(I gotta believe that the shorter pipe and minimal bends flow a bit more), but cost was a key player as well. The local shop wanted $350-400 for standard crush bent 2.5" pipes run side by side in the factory tunnel and $400+ for a 3" single with a custom fabbed Y-pipe to fit the LM7 manifolds. I paid $25 for 2 mandrel U bends and the rest I had lying around. So I at least have close the same level of performance as what they could have done, and an extra $350 in my pocket I can use toward something else.

As far as SFC's I dunno. Ive never used any. Im sure they could be made to fit, but on a sub 400hp car, the benefits of those are debatable as well. If I put 300hp on the ground I'd be tickled pink.

They are what they are functional and agressive. I like em On a side note though, I wouldn't dare try to stick a tip out the side. Even a boom tube, tho as cool as the look is a good way to burn someones leg. :/
