Trying to put a 2000 or 2001 heads upper and lower just need to know the size pipe to put .florida no catc....

i think 2" pipe. you can also try a SEARCH or maybe look in the stickies

Thanks....if you know anyone with some spear parts can you let me kno....I'll work something out for them..

2.5"

I thought it was 2.25"...

The WIZARD wins!

My 98 is currently raised so I measured the outer diameter of the y-pipe and headers with my calipers.

Headers to Y-pipe > 2.25"

Y-pipe to CAT > 2.5"

Since the original post was very detailed, I had inferred that he was asking about aftermarket exhaust sizing.

Nice thanks...trying to get the manifold and exhaust by this weekend..anyone have spear parts they don't need making that trim to ny to fix her up...
