First of all, what diameter is the intermediate pipe on a 98 SS,
Second, for all of you that do have cutouts where did u have them installed on the system, and where did u get a turndown
Three, how much louder , how much performance do u gain ( not necessarily numbers but can u feel it?)

I put mine a little after the passenger side CAT.

Mine is under the rear seat. I think you'll be happy with the cutout. Are you still running cats? Back when I had cats I ran mine open 24/7.

i have looked there, couldnt find it
02-05-2007, 01:36 PM #11
alright i found it but they're too long, i've seen people that have short ones i need one of those
02-05-2007, 01:37 PM #12
I could make you a set?

yeah i through in a cut out for sound only.. if u ever decide to run an ory without cats, you won't want the cutout open, you need back pressure for power. since you still have a stock exhaust though, you should feel an increase of about 6-7 i think. and it'll sound niiice
02-05-2007, 06:20 PM #14
yea i'm hopin for that, i know the power aint much but i hope it sounds good
02-05-2007, 06:25 PM #15
its a decent increase and hey, every little bit counts, and the cut out will definitly sound good good luck man

yo, uconn just rejected my app.. lol
02-05-2007, 06:28 PM #17
Why don't you just go with the Flowtech turndowns with 3 bolt flanges allready welded on and cut it to length?
