Good clamps. Replacing the flex with a ZZP flex pipe is recommended since the one that comes on them tends to go out real quick. O2 extension...but I ended up just making my own. You can either keep the test pipe or weld or clamp in a catalytic converter but remember 04s would need the codes deleted if you decided not to run one. I used the spark plug fouler trick myself but will be getting a magnaflow cat soon.

thanks man! I recall seeing somewhere NAPA has good band clamps..?? 2- 2.25" and 2- 3" correct? will any flex do, like a good one from a parts store or exhaust shop, or should I just go thru ZZP? Ill check out zzp now, as Im assuming they will have the o2 extension as well? also, will I need any new donuts, or rtv for the seams?

I will eventually be getting an overkill pcm once I know for sure what my mods will be, so I will just have him delete the rear o2..


Also I might need a new flange, because I cut the resonator out, and the flange that bolts the rear section to the DP
