Any pics of your install? Advance Auto near my has it in stock and I found a 30% code so the Thrush only cost my $28. I also plan on leaving the stock resonator on. Looking for me sound, nothing too loud.

 

I did a flowmaster super 40 series muffler replacement. Very little change in sound at all inside the cabin, very little change outside the truck as well. After i did this, I more or less chalked it up to a weight reduction mod ... maybe a little smoother exhaust flow and thats about it. If you want sound change you need to remove the resonator. Sure a resonator delete pipe ($20) and muffler (60-100) is cheaper than a new cat-back, but make sure its at least welded up.

 

Zero83,

I'm guessing you cut the resonator out too??? I had a shop swap out the stock exhaust for the Thrush 17656 and there is no sound difference.

 

Hi All !
Any Magnaflow muffler for a 4th gen camaro will do the job nicely, and I got mine for $104.00. The only thing to be aware of is the inlet pipe diameter, because there are 2 different options for that. Labor for install and tips set me back another $260.00 but I am quite happy with the setup !

When I purchased my brand new H3 in 2005, i went to a local muffler shop that did magnaflow. We looked at the bottom of the truck and decided on one. He cut the old and welded one in. $200.

Don't waste money on a cat back, don't waste money on a bolt in....just see a local expert and they will weld a very nice one in. I still have the muffler and its awesome....255k miles on it.
