Okay I am running the VTSC w/ AC and a Spoon TP (70mm) to an HKS hi Power dual (60mm). There is a great deal on T1R products right now at A&J Racing.

Would the T1R 70mm header back exhaust show that much of a gain to warrant the $600? If it would add 10-15whp, then I am down to throw money around.

BTW, when I put this on I will be pushing 12.5lbs of boost with a 4in pulley and 725cc ID injectors.


Just want some people who have experience with both dual and single exhausts.

TIA


SKATE-

 

I made good power with the Invidia duals.
I know on a stock motor, the HKS doesn't really make any power by itself, so it really depends on your budget.

 

not really a budget issue. I have the HKS right now. And I have plenty to spare on the T1R. but that doesnt mean I want to waste it on the T1R. Im looking for someone that has changed out or done dual to single and seen an improvement to justify the purchase. Not trying to be ungrateful to your response in any way. Just clearifying.

Cheers

 

that deal on the t1r exhausts,........i highly doubt any of them are "in stock". id check before you get your hopes up because 50% sounds too good to be true on such a high priced item.

 

I have t1r 70mm single and I can tell the power gain, but not sure if 15whp.

 

single always makes more power then dual, but id imagine you'd see maybe 5-8 whp at most

 

get the sparrow or the drone will kill you
