Greddy Evo Cat Back on Turbo'd Car
 

I was checking out Greddy's site and couldn't come across the size of the piping used. Would the catback's piping work with a turbo with a turbo? Is it 2.5 in. or 3 in.

I'm almost positive that it is a 2.5 inch pipe. My buddy has it on his Si. I think that thermal R&D is the only one that sells a 3 inch cat-back from the factory. Everywhere else is custom 3 inch.

yeah the evo is somewhere between 2.36" to 2.75". and thermal has the 3" exhaust. i sell them for 620 but i can work the price a bit

I found a place in Ohio that sells the greddy evo and greddy turbo at a great price. The exhaust cost me $417 and the turbo kit was under 1400. Yeah baby, soon to be boosted. Shipments should arrive sometime this week.
