uniacidz:2147333 said:what's the difference between a tri y and 4-1?
Try-Y better for low down response, torque etc
4-1 better mid range to up top
Personally I rather have low down response. Tis the speed range the car is generally driven it and i can always use good cats and other mods to improve up top.

ok thanks heaps,
with the cat back, is it better to run a single 2.5in or twin? i guess the same can be asked for the 3in variants too. which is better, single or twin cat back?
