I just installed the GT muffler I ordered from Casco $30 +25 shipping (New take-off from 05 GT)
It installed in about 30 min with zero problems. Sound is great, a 110% improvement over the stock V6 muffler. I have a video clip w/ sound, but I can't host it. It's almost 13MB. If anyone can host let me know. Here are some pics. I had no problem with clearence between the tip and bumper as others have stated. The best $55 mod hands down.

 

Welcome to the club...

 

If you think that sounds good! Wait til you put on GT duels, They sound so much better than a single GT takeoff.

 

I concur it is one of the best mods, I am still torn about adding the second muffler though

 

I can't wait to get my other side done, have to wait til after vacation end of the month though

 

Yup....I like the mod as well. Can't wait to do the duals. Did you have any prob with the tip being too close to the bumper cover. Mine is REALLY close...gotta fix it when I get time.

 

No I have about 1/2" all the way around my bumper slots for the muffler tips. The key is to make sure that the muffler goes on the exhaust pipe all the way. You'll notice this by the little stud on the muffler goes all the way up into the slot on the exhaust pipe. Just keep the clamp loose and tap the pipe with something (hammer or wench) until the end of the slot and the stub touch, then tighten the clamp. With this done you should not have any clearance problems.

 

Brad offered to host my sound clip, here it is
