yeah those are good. almost to good haha.

hope so I never like that dam oem clamp, as noted it's never tight enough, doesn't matter how many ugga ugga's you do

on my 00 I even ended up replacing the flanges, more than once I would warp them every few years
only place to find them is the junkyard

the smoke test on mine was leaking pretty good even if it's only a tiny leak I don't need it giving me more brain damage than I already self inflicted lol

I have an AP muffler, and I think it may have been the same one. It definitely has less drone than the MBRP clone muffler I have installed now, but it quiets down the overall sound as well. I wish I could have my current sound, but less interior drone.

Might buy that QW muffler and play around.

The other thought is to buy the short version, but also grab another short, but wider, muffler/resonator in case the QW muffler is obnoxious. I wish mufflers had a strong 2nd-hand market like gun parts, lol.

Do you have headers? I have long tubes, so that adds to the growl.

Just cast iron manifolds. Not ready to throw $$$ at LT headers, welding in cats, and a new tune when I just got the last iteration of my tune running decent.
