Default Quieter Exhaust

Currently have stock headers, gutted cats, and a GMMG cutback with an inline resonator. I plan on going with long tubes soon and would like to quiet down an already loud exhaust. Ideas? Will cats be sufficient or will I need to swap out the mufflers too? I would like something reasonably quiet at lower rpm but loud at WOT. Suggestions?

From my experiance, the cats didnt help noise wise, but they were key with reducing rasp. These are loud mufflers, sound great and flow, but loud. If you want to quiet it down you'll need the cats, and throw a Magnaflow 12649 or 2 on there as well.

So you want to get quieter but you are putting Longtube Headers on?

Buy a quieter exhaust system and then sell your GMMG exhaust.

GMMG with Longtube headers sounds really good, I would reconsider selling it OP

some towns are stricter on their noise laws than others.i don't blame the OP for wanting something quieter.

IMO a magnaflow is perfect. Nice and quiet driving around with zero rasp and opens up at wot. I have one with a cut out for when I want to be loud.

+1

Stainless, straight through design, nice deep tone at idle / cruising, adjust the volume with your right foot
