Not only can you put true dual exaust on your 3rd gen, your certianly gonna want to for more power! Or if you simply just want a meaner sound get a flow master 80 series muffler to replace the stock. I have yet to get some headers due to the fact im not in the us rigth now, but ive been told to get some edelbrock tes headers. now the thing you gotta look out for is how low they hang off the bottom of the car, itll pay off in the end to clamp them to the bottom of the car as close as possible to not to get your muffler or cat ripped off by the crappy streets

flowmaster 80 series is gonna give you plenty of sound. Any mufler should be able to sell you one and weld it up for you. I just have a small problem with them because they drone at highway speed. but they are plenty loud and sound great!

[IROC Z 1988]

The thing with bassani is that it sounds great idling and accelerating but it doesn't drone at high speeds it sounds even louder it doesn't give up sound. But the bad thing is that when I'm stopped at a light and I accelerate it switches to second and third gears to fast almost before I leave the intersection depends on how far I push the petal. If thier is a way to change the gears so they would last longer with out switching to fast let me know.

My 700r4 does that too. Maybe with a shift kit it wont do it. But its weird because it almost seems like it up shifts and engages overdrive at the same time.

a true dual is pretty agressive, and probly not worth the trouble, i have edelbrock TES headers and flowmaster american thunder 3in exhaust on my 89 and am perfectly happy with it. its damn loud and definatly boosted performance. if you run true duals, i suggest two 2in pipes, maybe as big as 2.5in if you have a highly modded engine.

[IROC Z 1988]

thanks 89 I think I'll run 2.5 in that is what i have now

Myth!
A single 3" exhaust will flow MORE than a dual 2.25". There are also other benifits to a single large exhaust.

...really how so?

I have a 87 IROC of my own and put on it high flow edelbrock cat 3" pipe all the way back and a 80 series edeldrock muffer with 2.75" outlets to duel exhust tips. I also gutted the cat. I also had my stock exhust manifolds finshed, I put on Mr. Gasket exhust manifold gaskets and My camaro sounds sick. she purs through every gear. Also for your gear ratio problem i had my trany rebuild with shorted 1st, 2nd, and 3rd gears fourth being long and 5th being for upto 120 or higher, or overdrive at low speeds. It is the way to go.

whats up guys
i had a 85 IROC i had a 40series street muffler with dual outlets
with a single 3 inch exhaust without any cat converter,it sounded wicked . it had thunder from down under.it sounded like it would leave the earth, but truthful i had a s-10 with 4.3 that would out performe it.
the IROC WAS JUST A 305 , but it was a crowd pleaser.factory yellow paint t tops sound system and the nrumble of mean machine.it was a panty dropper
