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"



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.)

 

i hate u now!!!!!!!!!!!!!

















j/k

 

please dont hate me





dont know for sure if the RB dual restricts power, but, i never seen one made over 400hp at the wheel with them

 

if u do that gb my friend wants one
