This is a monster! http://www.evasivemotorsports.com/merchant...e=GREDDY_PE_TIR Would there be any benefit on our cars from this exhaust or is it so big that it would be pointless? I know that a few companies such as Amuse and J's and T1R make 70mm systems but 80mm? How loud would this be?

 

i think it would be realyl loud and need forced induction to properly utilize the piping diameter

 

It would work best with F/I but I did a lot of research on exhausts and read that a 3 in exhaust would create some decent power with some GOOD tuning..

 

80mm is 3+inches, thats should be good if you run a TURBO !

 

interesting as it is not on the Greddy site.

 

May I ask what kind of research?

 

I wonder if it's cat-back or header-back.

 

i think it's a catback, i don't recall greddy making any turbo/header back exhausts..

 

I would rather have the T1R 70R.

 

Yes, hk s2k is correct. It is cat-back.
