i have the Greddy MX on my car..i belive the pipeing is close to 3in

i believe the piping on the greddy mx is 2.5in. since its made specifically for a mkiv normally aspirated, you'd probably get the most performance out of it.supraspeed01 said:My stock pipe is about 2.5 inches in diameter.
How does everyone like the performance of their Greddy MX? Does it seem to have the right size pipe for the NA?
Thanks
