Default Would the GMMG catback be comparable to SLP?

Mainly in the area with LT's ? I'm asking because i don't want loud, annoying rasp as with LT's and an SLP catback. I've done a lot of looking on youtube and am still just confused I know the GMMG seems to be one of the best you can buy but does it's design / performance make for a bad tone with a full exhaust?

I'm looking to do pacesetter Lt's, Y with some welded up cats eventually for emissions, and then the appropriate cat back. Either Magnaflow or GMMG is what i'm debating.

If you go with GMMG, get a powerstick and intall it in the I-pipe. That's what I did and it removed most of the rasp. It also fine tuned the deep rumbling sound and made it a bit quieter. You will love the GMMG for sure. Good luck.

I didn't notice any power loss at all.
