so im debating between which one would give me the better overall performance. im planning to keep my car n/a and was wondering which exhaust would be better the 60rs or 70rs. i hear from some people the bigger the better but and i hear from some that with n/a cars you need more back pessure to produce power. i currently have the 70rs on my car and im planning to add a test pipe before i get it tuned, but jus wanted some opinions. i chose the 70rs cuz im planning to go itb's later on and didnt wanna change exhaust if i got the 60rs now, and jus wanted to kno if im on the right track. thanks guys in advance

 

70 all the way.

 

you made the right choice =0)

 

70

 

70RS was the right choice. Love mine!
Get that TP slapped on. Reduces drone, exhaust sounds even better and you'll gain some more power.

 

^And your car will smell bad!

 

what if like in my case, with a supercharger, whats better, the 70rs or the 70rr?

im worried that the RR would be too loud, and im worried that the RS has a resonator. they say that resonators would break under FI pressure also reduce potential power.

my current exhaust is the T1R stainless steel single 70mm. i wanna go TI. is the RR much louder than my current setup?

 

There are different versions of the T1R single 70mm, which one do you have?

 

How much louder is the 70mm then the 60mm? To loud for daily driver use?

Also, can someone please tell me the difference between the 70RR and the 70RS?
