are there any performance differences between these two cat-backs? any sound differences? or any differences at all?
any info is appreciated

 

I have the JDM exhaust so I will tell you that it is the best sounding and best tips so I can justify my $525(I think).
Now I am sure somebody who owns the Bassini will say his(or hers) sounds the best and he (or she) has the best tips so they can justify there $625.
If you are buying your cat-back for performance save your money.Maybe 10 h.p.
You have to hear and see for yourself.Try to go to a meet .That is what I did and heard all the systems and made my decision.

MM/FF did a dyno on the bassani and had a 1 hp loss. They left it on cause they loved the sound. It was a stock truck at the time.
