[nando]

wiechers sport. I don't think there is any other one made for the ix..

[Digitalwave]

Did you use those collectors and then have custom piping made, or did you match it up to the stock stuff after the collectors?

it's 2.5" into the stock cat. I'll ditch all that when I do the bottom end of my motor, but it's more than enough for now. my intake is now the biggest restriction (completely stock).

correction...your head is the biggest restrictions ....the biggest exhuast and the best intake wont do a damn thing except add sound if you keep your head stock i suggest either extrude honing or port and polishing

Extrude honing isn't for heads, it's for intake manifolds.
