I would like to know which of these two exhaust would be the most efficient whitout any other modifications (eventualy air intake).

J's Racing FX 60 RS or T1R 70-EM Sparrow

Thanks for your answer

 

you'd be golden if you got the t1r and a 70mm tp to match!

 

I plan to put a header and a test pipe then

and I would like to know if the FX60RS is very noisy?

 

I got the fx60rs, after having the invidia dual and the 70RR, the 60RS is a god's gift to me... love it everytime!

VERY silent in low rpm and highway cruising, almost like OEM... but when you hit vtec top down, it screams almost like the 70RR! Fantastic!

I won't be afraid of getting trouble with the cops anymore because when i drive normal, the thing is very silent and discreet.. It makes noise when you floor it, and thats a big plus!

Best exhaust ever and it's never gonne leave my car again

 

best exhaust out there for DD.

 

Thanks for your answer!

 

You should research more into both exhausts. If I were you, I'd get 70 EM for sure.

 

my J's racing 60RS single drones alot between 3-4K RPM. annoying at freeway speeds and driving around at times. sounds very nice. not sure if the dual drones also.

J's 60RS (not the dual, but close enough)[media]http://www.youtube.com/watch?v=E2rXn0iOe6E [/media]

 

t1r stainless steel makes more power. dyno against j's is on evasive's website.

j's cost more and weighs less. made of titanium.

 

j's FTMFW

i have the j's and its the best exhaust i ever heard for the s2000
