What was the change in peak TQ?

 

I noticed that evasive has the t1r exhaust labeled as the "t1r power header" and aj has it listed as the "t1r response header". Is there a difference?

 

ooo thats a tough decision, id think long and hard bout that one.

 

So the T1R is basically an exact copy of the Tracy Sports. Should explain why it works.

 

It is the T1R response header , evasive actually gets there headers from AJ racing, The torque was 136 and now was 144 . Im very pleased with the performance gains the car feels so much diferent. The torque stays flat at about 140 untill it drops at 7500

 

Thats great, I just ordered the T1R header from Evasive...

 

how much is the t1r header???

 

850 from AJ racing and 900 from evasive

 

i believe Evasive has free shipping on the header but not AJ Racing

 

Well I have the HKS header you have the picture of. It is a quality piece no doubt. Also the sound from the exhaust now is pure sex. OMG it made the car sound so much more throaty its insane. By far the best mod so far. Granted I have a 3" header back with a resonator and magnaflow canister so all the noise gets out
