Default Custom exhaust opinions wanted!

I'm wanting to create an exhaust that is a replica of the slp "powerflo," but with chambered mufflers instead (similar to the ones gmmg uses). How do you guys predict this would perform/sound? The "powerflo" looks like it flows well and i love the sound of gmmg, but powerflo is $700 and gmmg is $750... I might just go with a borla xr-1 in a loudmouth. How much rasp would i get with an ory and borlamouth (ill be using an arh y which has a good merge. That may reduce rasp a tiny bit)?

Both are overpriced and the GMMG sounds like fido's *** with ory.

I would get a TSP Rumbler catback and add some magnaflow or borla round mufflers in the tailpipes where the slp powerflow mufflers are. You will end up with around 550 with Borla mufflers and 450 with Magnaflow.

well i love the sound of gmmg with cats... and im getting cats so that works out pretty darn well. Thats a good idea but id perfer stainless, so when you look at it that way im still getting it custom built with chambered. Anyone elese have and idea how it will sound/perform with chambered exhaust and cats (should have mentioned im going to use cats)?

I forgot that the loudmouth was stainless. What do you guys think about a "chambermouth"? Has it been done before? If so what were the results?

If you put the chambered mufflers where the mufflers are on the powerflow exhaust they will probably be too long. If they do fit then you will likely end up using the muffler as the tip itself which will look like hell and probably sound like it too.

I understand you want what you want, but those chambered mufflers are junk IMO.

I was actually just thinking a loudmouth with chamber muffler where the resonator is and use cats, but i dont think will sound much like gmmg so i may just use a borla xr-1... the sound of gmmg is either too expensive or too much trouble to replicate.
