Normally I'd say" Man this place is sounding like the corvette forum more than ever with remarks like that.."; but I'm going to try and not be so confrontive this next year...

On the other hand... but I do doubt you can get your muffler resized to 3" AND mig-welded/heli-arced for 75.00 per...unless you can expertly DIY. If you read his entire post (or others he has on this mod) he tried several configurations of the innards to find the best combination; so I'm assuming he thinks his efforts are worth a few $$.


I just keep a series of interesting links to stuff done on Z06's as I have one. In many cases the same fix applies to the Z/28 as its essentially the same mechanicals as the C6-Z06 Z07; w/ a .391 rear end thrown in for good measure.

For $75 per id give it a go. Cut the inner pipe, weld a sealed 1, and call it a day. I was going to do the muffler mod on my c6z, but I got some corsa sports for 400 shipped. I dont want anything resized. Just really looking to get something louder, while sounding BA. There was a guy who had done the mod on his 1le npp, and it sounded great. Better than the vette muffler mod for some reason.

Its done. https://youtu.be/YVei5LfeD7w

40% louder, definitely sounds deeper. It also has more snap, crakle and pop.. getting cam around the 11th, so well see how she sounds then worth it for $150. Took about 3 hours to get done. Overall im satisfied.

I thought it was your 1LE! It looked like you also have a Pontiac G8.Around here we're just guessing on that model...do those things even come as an NPP muffler ?? I used our friend search: and found a NPP build thread on the forum below.

Edit: ahh..searched your profile on CF and found your 2008 G8 pics, have you still got your Z06??

Dont have the G8 anymore, but still have the C6Z..
