So I noticed my car was getting louder and louder lately...took it to the shop and they confirmed there is a hole in the top of the driver side muffler.

They checked what a new muffler would be from GM....$1400 bucks.

I guess they make them out of titanium now.

Are the Magnaflow's still popular?

I believe you can still use the ZZP mufflers on the GXP, same exhaust setup.

I know walker also sells an OEM replacement for the GTP's that works with dual exhaust, they have them in both single and double tip ends.

just find a sound you like and go with that. i think you just need an offset in and center out muffler. a muffler shop should be able to get it cut in without much of a problem.
