Grab the pipes and yank em around. See if you can find the pipe that's hitting. It took me four trips under my car before I realized it was hitting the trunk.

Varify if it's hitting the one pipe it's almost laying on.

 

Problem solved.

The over axle pipe was hitting a bar under it once the pipe heated up and expanded.
The pipe was also somewhat loose where it was clamped to the x pipe so the clamp was tightened as well.

ALSO... because of the angle of where the muffler and over axle pipe met... the muffler was actually hitting the plastic part of the bumper at the cut out when heated up. This was noticed because it actually melted a small part of the bumper.
Not to worry though... it is not at all noticeable unless you get under the car.

The shop that fixed it told the the clamps that came with the setup were crap.
They said it had a chance of coming loose again and that if it did they suggested tack welding it.

Nice guys. The owner is a friend of my step father and they actually did the work for free.

Now all I hear is the great sound of the exhaust with the cams.
And the Bassani's DO sound great with my setup.
They are actually the race version with the coke can shaped muffler.
My friend that I bought them from sent me the wrong pic and it was a pic of the chambered version.

Oh well... they sound GREAT with this setup and I notice no drone at all.

Finally I can settle down and enjoy all the mods I did this summer.

 

Get the pypes mid muffler! Out of all the mufflers I have tried these have been my favorite. I have them coupled with mac longtubes and prochamber and the sound is ridic! They remind me of my previous stingers except more refined with almost no drone.. PMM FTW
