im in a debate whether or not to ditch my t1r and get the j's 60rs....im going to order the header, and i cant decide whether or not to get the 60rs with it...does anyone have dyno graphs of the 60 and or the t1r 63...i know someones first response is to go with the j's 70 for the biggest gain but i dont know if i can spend the extra cash...errrr...someone help me!

 

 

from what AJPWR said the t1r will make better gains but it weighs more

 

Stick with the T1r until you can or want to upgrade to a 70mm.
The Js 60 wont do anything the T1r 63 cant (or at least for the price).

 

i was going to ask this same question, but with the 70mm exhausts. j's weighs less (how much?) and doesnt have the resonator that the t1r has. is there much of a sound difference?

also does the header change the sound much?

 

J's 70RR weighs about 10 lbs and the T1R 63 weighs about 27 lbs. Thats the difference between SS and Ti.

With the J's header, exhaust sound will be a bit louder.

 

you said you are going to get the header also, thats where the high cost is going to come into play. whats the price diff between the j's 60 and the j's 70? like 500 im guessing? i just got the t1r70 because it had great gains and it was somewhat affordable at under 1000 for a great exahust. sounds great btw, and i can really feel the HP my JIC magic exhaust was holding back.

 

i love mine

 

anyone got sound clip of the 70RR?
