Default slp dual duals

Looking to get rid of my factory slp exhaust, little quiet for me. Is the corsa and gmmg exhaust pretty much comparable in construction and quality? I like the sound of both and what should I be able to get out of my slp exhaust? The car has right under 10,000 mi.

both gmmg and corsa are solid exhaust , few earlier corsa systems would blow out the muffler but i believe they got this resolved. corsa will have more droan inside then the gmmg though. both will also get extremly loud if you ever go headers and ORY

You might get a louder exhaust by getting rid of the SLP Dual Dual, but you won't gain any additional power going to the catbacks you mentioned. The Dual Dual flows very well.

I hope you plan on running cats with your new catback. If you don't they're going to sound crappy with an off road y-pipe. The Dual Dual soaks up most of the rasp with an ORY. Keep your future mods in mind when selecting a catback.

Add some LT's to the SLP dual dual and see if you think it's still quiet.

My exact thoughts... If LT ORY are in your future I would keep the dual-dual. I have it with LT and ORY and it sounds very good. Not raspy, not annoying, quiet at cruise, but flows well and sounds good on throttle. I don't see any perceivable HP gain with the muffler vs without. IMO it is a very good exhaust.
