Alright im wanting to put a set of longtube pacesetter headers from texas-speed on my 03 wbh 5.3 Avalanche and im am removing the cats and want to run true duals 3in with an h pipe.
what would be a good muffler choice?

how would two Dynomax Thrush Stainless Steel Glasspacks 3in in and out,and 25in lenth sound??

or two Dynomax Race Magnum Bullet Mufflers 3in in and out, and 23.5in long sound??

And also I am looking at getting a cam what would be a good one to get?

 

I am running true dual with x pipe and magnaflows. I love the way they sound!!! Unique, and not like everyone with chokemasters.

 

which mangnaflow?
what size pipe?
