Re: exhaust ideas?
I know that many people who have done duels on a third gen have had ground clearance issues. There is really only room to fit one pipe properly under the car. You may bea able to put two pipes side by side. I would go headers and a 3" exhaust at most then a cat-back. Dynomax make all the piping to go from the cat to the tips. I would also at least get a highflow cat or delete it, I got mine deleted and my 2.8 sounds so much better than before. Much louder and deeper.Comment

Re: exhaust ideas?
2 flowmaster 40 series, (very inexpensive), headers -> straight pipe -> mufflers just before the axle then just have little turn-downs before the axleOriginally posted by 96greenmachine

Re: exhaust ideas?
car may be exempt from nazi e-check, but having no cat is a federaly no-no. at least have some special cats to give the look of legality ( i had one on my 77t/a and it made the exhaust deeper/mellower). I've seen true dualls set up for 4th gens running the same way as regular exaust, adn I've seen one setup for a third gen w/the pipes exiting out by the pass rear at an angle, really slick.1978 Formula 461 in progress of being built :rock:

Re: exhaust ideas?
Many years ago when the 3rd gen Fs were the in thing, I saw a magazine article (can't remember which rag it was) where the guy ran 2 oval shaped exhaust pipes down the length of the driveshaft tunnel. As soon as they get up to the rear axle they (the pipes) can be routed a variety of ways.Now Playing: \'99 Pewter Firebird, stock, bone stock, and nothing but stock, so help me God!<br />Comming attractions: K&N Filter, Lid Mod, Intake Bellows Smooth Pipe Mod.<br />I dream about: Forced Induction (TC or SC) or NOX (or both!)Comment

Re: exhaust ideas?
I do know that there was an option on IROCs that was called the duel cat option. It was basically duel exhaust after the y-pipe.Comment

Re: exhaust ideas?
they also make headers with dual cats on the headers for 3rd gens too i beleive...so i could have 2 strait pipes going out to mufflers then out the side...Comment

Re: exhaust ideas?
My buddy put true duals on his 89 iroc. not gonna lie it was a big pain in the @$$. I believe he bought a kit, don't know witch it was about six years ago. He used a couple of small high flow cats from jegs and brought it right down the factory channel. You'll have to tach weld the pipes together with some small brackets so they dont rattle. your best bet (unless you have experience and equipment) is to take it into a muffler shop.Comment
