Hey guys, need all you help.........
I just can't make a decision on some of the exhaust system, they all sound really nice, I just want the one that can give me a little gain, don't want any lose end torque, which one you guys prefer?
Blitz
Espelir
Ganador
Impul
Jic
Rsr
Greddy

 

I saw a G35 with the Greddy EVO2 and it sounded pretty damn good! Id go with that.

 

I recommend that you

a. Set a budget.
b. Decide what configuration you want. Single. Dual. One or two mufflers. Y-pipe?
c. Shop for catback exhaust systems which meets your budget and selection criteria.
d. Pick your favorite.

 

except that the cross over pipe narrows to a single diameter that's smaller than stock

i've heard it in person too... sounds good but like other members on the board I would swap out the greddy x-pipe for something more efficient
