OK, I just ordered my boomtubes. Any things I need to look out for when installing them? I didn't have any real problems with the Flowmasters so I'm thinking it will be about the same. I'm hoping the final result is not obnoxiously loud. We'll see though.
On a side note, if anyone is interested in buying my Flowmaster ATs or a stock GT exhaust, PM me. Both have very few miles.

 

I had no issues with the install except that my hangers probably need to be bent a little since one tube hangs a little lower and points off to the side more than the other one. I think midpipe adjustments help when one sticks out further than the other. Mine were pretty even in that regard.

no major issues.
and they're not obnoxiously loud, but just right. loud when you get on it, not that loud when you're not.

 

No issues with the install. However my drivers side tip is a little off center. I plan to fix it when I get some time. Like riptide said I think the hanger needs to be adjusted or bent a little.
