Exhaust Last Exhaust Related Question Before The Install

Ehh; seems like clamping to the end of the collectors and just cutting off the end of the pro chamber might be the easiest way. You really don't even need those hangers on the prochamber if it became an issue. I don't use them because the exhaust so too low and I'd get stuck on speed bumps (my car is low, but certainly not slammed). So without using the hangers you can actually tuck the exhaust up a little higher.

What kind of collectors are on the headers now anyway; just straight 3" pipe or flanged? You may just need a pipe expander where you cut the pro chamber and collectors if you're removing a flange. Other than that I don't see why not.

One final word of wisdom is that no long tube header is 50 state legal; they just simply aren't.
I know you said you were using cats for sound reasons, but you finally will need to have it inspected and it's basically a crap shoot if the person cares or not. In NJ they have CCTV to view under each car. 9 times out of 10 they're only looking for the cats, but if they cared or knew the laws & realized you were using LT's, they could fail you.

Just something to ponder. Anyway, your idea sounds fine and should be no issue. Band clamps are fine, just don't use these:



Something like a t-bolt clamp is good:



just get these
