Default Which Catback to go with?

Ok, I have an 04 gto m6 so far exhaust wise I have jba shorty's, off road mids, and a magnaflow catback. I'm lookin for a some more noise out of the car. I am trying to decide if I should buy an lm2 catback, or spintech. I love the sound of both, what are your opinions??

Other mods, K&N, NitrousOxideSystems wet 100shot, torquerV2 cam, patriot dual gold valve springs, patriot 7.4 pushrods, motor mounts, and rear end mounts for the drive-train slop.

I have had Spintech and it had a great sound. It will definitely be louder than your Magnaflow.

The magnaflow catback is the quietest exhaust setup for the GTO, probably quieter than stock. So basically anything will be louder than that.

The spintech sounds much better than the loudmouths IMO, it has pretty good tone and volume. You won't be disappointed.

I agree my friend has a gxp and he just removed silencers and his is as loud as my catless magnaflow.... My favorite video is the guy who has the gto with dynatech headers, catted mids, and spintech dual rear, 228r cam on youtube, so far no lm2 likes which makes me lean towards spintech a lot!

Magnaflow is in no way quieter than stock. OP I would swap the mufflers in the system with some Borlas

I had cors sport and loved it, now i have a full 3" custom borla exhaust and it sounds Orgasmic. Buddy of mine has Spintechs, sounds good but a touch load for me and he is just boltons.

Another vote for the Corsa Sport. I have cats and can wake the dead, but at cruise it's nice and the best of all.... No drone at ALL!!!!!
You get what you pay for.
