H3 Exhause - Flowmaster 40 series installed
For those wanting a good sound without the full cat back system, installed flowmaster 40series, single out and was surprised how well it sounded on H3 3.7L. Left on resonator for now (afraid of cabin drone if remove)but may take off once the muffler breaks in. Will try to post sound later.

not to be stupid but how are you guys putting these on? you cutting off the old one and clampping the flowmaster on or welding it on? I want to put on on mine but i dont want to cut off the factory put this one on and if something goes wrong with my truck they tell me i voided my warrenty cuz i cut the original off.

You can have your exhaust guy weld on a sleeve or transition piece right after the cat so that you can just clamp either the stock setup or aftermarket setup. Personally I'd rather weld it on because once you do anything to your exhaust, you've voided the warranty anyways. Just MHO here, gotta "Pay to Play" so to speak.
