ok im new to this site and i think this is where i post stuff about getting more ponies out of my car. ok well i anve an 86 Iroc and it has a crapy 305 in it w/ stock 4 barrel carb. i want to put a new exhaust system on it to make it be hurd while going down the road. like a rumbul of the old big blocks. i dont kno wat size exhaust to get for it. and w/ this new exhaust will i need to adjust my carb? ne info would help out a lot.

 

Being new here, I hope you would proof read your posts before submitting.

 

Any 3 in exhaust would be more than what you need. I am running a car that makes about 410 HP at the wheels with a 3 in exhaust.

 

hey, another ohioan

well, this is what i'll be installing soon and it's supposed to be one of the best
gmmg chambered exhaust
flows on 600hp machines just fine and they barely pick up any horses when they go cutout
so it will definately flow for what you're building

a little pricey (believe me, i almost didnt get it) but i know of a place where you can get one cheaper

what kind of mufflers are good for 3rd gens? i have an '87 IROC-Z 350 tpi and am thinking of redoing the exhaust, but want to know what kind of mufflers are good. hopefully under $120. im already sure im doing a 3inch from headers back and taking out the cats.

 

Do you want "good" as in quality or as in low dollar? If you want a good system, it will cost you $700 for a Borla system that is good and will last forever. That is a complete cat back system made of 304 stainless steel. SLP is also good around $400 and is made from SS although not as high quality as Borla so it will discolor but will be fine.

 

i was thinking good quality sound for a fairly cheap price. thoughi was thinking muffler not whole system ill just have a system hung at my uncles shop. though this thinking just took a dive since my tranny just took a dump.although depending on how much itll cost to fix i may be putting in a t56. it would go great with my 350. since they didn't come with manual trannys.

 

If you are thinking good for a low price Flowmasters is what I have on mine for a catback system. on the top end We went with the Eldelbrock headers.


Oh by the way Mines a 87 Iroc 350 with the HRS in it.
