I've been trying to decide what to do with my 07 max truck for awhile now. Here are my choices,

Corsa, very nice, choice between sport and touring but big dough.

Magnaflow, cheapish, heard some people complain about the sound in 4 cyl mode

Borla, good quality, no option for sport/touring, no idea how it will sound

B&B, seems to be good quality, again no option for sport/touring, cheaper than corsa, but still spendy

Gm performance, I swear they are a borla piece, not listed for a 6.0 liter but will fit

If I had the choice I'd go with something touring, not interested in loud, just a nice sound that won't annoy me on a day to day basis.

Also thinking about headers, only one choice there, Dynatech. Just waiting to see some real world numbers on the dyno before I dust off the piggybank.

Thoughts, feelings, suggestions?

Just bought a GMPP 'performance' system. It is Borla. It will be a couple of weeks until I get it installed but I will post my thoughts. The quality though is top-notch. I too worry about the 4-cyl mode but I figure if GM puts their name on it and dealers will install it, it has to be pretty mellow to avoid pissed off buyers.

 

I just bought the Corsa Sport dual for my 08 NNBS CC 6.0. Under reasonable driving conditions it is not that loud, but when you put your foot into it, then it wakes up, nothing insane, but nice and throaty. I have had it a week and am still happy with my choice based on it being a bit louder when the foot gets heavier. I drice the family around in it and they have not complained either. The touring is quieter but I dont know by how much.

 

I've installed quite a few sets of the GMPP exhausts in the past, top notch stuff. I swear that it's borla by looking at it but have no way to know for sure.

The thing that worrys me is that GM doesn't list it for the 6.0 even though it would physically bolt in. Makes me wonder if they know something we don't.

One of my suppliers has offered me a B&B exhaust to try, buy it if I like it send iy back if I don't, it's a very nice offer, just not sure if I want the hassle if I don't like it. I can't seem to find a pic of thier stuff anywhere, tips etc.


I'm really leaning toward the corsa, this thing is my daily driver and I really don't want a bad exhaust note to annoy me every day, know what I mean?

parts guy told me that the gmpp is just a restamped borla but im going with borla brand since i cat get it for a really good deal

 

hey man you mind posting a clip? im still undecided on what to go with due to the DOD. id like to keep it but dont wanna sound like ricey just cruising in town.

 

dont even worry about the dod. u cant really even tell the difference

 

hmmm ok. well im going to dump the exhaust do you have any suggestions? was thinking borla or a flowmaster. not worried about hp numbers just sound.

 

flowmasters will drone really bad around 2500-3000 rpms. nothing sounds as good as borla on a truck imo. you can buy a catback single for around 650 or the single in dual out for aroun 900. or just have the dealer do a single in dual out for around 500 using just the muffler. i dont care what anyone says either but you get better tq from a single in the exit style doesnt really matter
