what size headers, x-pipe do i need???
i just recently put a corsa catback system on my 01 coupe. the system is 2.5 inches. i want to go ahead and finish it with headers, x-pipe and cats. i have been shopping around and it seems like all the long tube headers have 3 inch collectors. what size headers, x-pipe and cats do i need to buy? will a 3 inch x-pipe hook up with my 2.5 inch exhaust? will the headers with 3 inch collectors hook up to a 2.5 inch x-pipe? please help

stock displacement engines do best for torque with 1 3/4 inch headers
You want 3 x 2.5 cats ( ie inlet 3", outlet 2.5") to hook up to your 2.5 " x pipe and the rest of your exhaust.

Get LT's that have the mid pipe and it will reduce down to connect up with your over the axle pipes...
