I'm thinking of getting a gen. 3 RX-7, and I would like to know what the best size of exhaust to put on it to get the maximum power out of a fairly stock engine. I can build the exhaust myself if needs be but I dont know where to start with figuring out how big I want it.



Help much appreciated

i got the hks TI i think its like 3.5



but u need to read the 3 mod rule before u start ******* with the motor







what dual exhaust? the gas tank is to big for that u would need to modify it. like a fuel cell or something.

you want 3"



mike

maybe he WANTS 9", but he'd do best with 3" https://www.nopistons.com/forums/pub...IR#>/happy.png



lol, yes im bored.



kevin

with 3" exhaust, you can easily support up to 600rwhp no problem.

oh, and by the way, i am thinking about posting a group buy on HKS carbon ti.



if we have 10 people, the price should be around $380 plus shipping. The retail is $625 + shipping.



HKS Carbon Ti

This is kinda off subject but, what kind of hp can the racing beat duals withstand? (if any problems with withstanding certain high hp #'s.)
