Replying to: obyone (Aug 06, 2007 7:12 pm) The dealer I purchased my truck from wanted almost $1K for the Corsa system stamped with the Chevy Logo. I love my truck, really do... but I won't be robbed like that.

I got a flowmaster on my z-71 5.3vortec, sounded great first year,nice growl at idle and a beast at heavy throttle. I like to let folks know where my money is going,,,to OPEC !!! but quiet enough to sneek through neighborhood when working till 4:oo am to fill the tank.   Long story short,the welds rusted where the pipe meets the case n the front and both exits. muffler case is in perfect condition,but cheap welds. going glass pack or Toyota next.

Replying to: donavin1976 (Aug 15, 2007 6:36 pm) How does Toyota fit into the conversation about your muffler? Is it GM's fault that you have crappy welds on a aftermarket muffler? America.... good God , we are truly our own demise.
#58 of 160 Corsa Exhaust by gravityprint Sep 03, 2007 (9:20 am)
I bought the Corsa Catback Exhaust from GMC when I purchased my 2007 GMC Sierra 5.3 litre. Beware, the spare has to be removed. It sounds great but does seriously resonate around 1800 RPM. I tend to drive in 3rd rather than Overdrive since, I dont like the sound the exhaust makes when it goes into the 4 cylinder mode. Gas mileage is expected to drop but its smiles to the gallon not miles to the gallon that gets me by. I am looking into a Cold Air Intake which may or may not change the tone a bit. Any ideas on the CAI? Sleeper Oakville, Ontario Replies to this message: anythingbuttoy (Sep 18, 2007 5:38 pm)

Replying to: schlog (Aug 06, 2007 6:40 pm) Does the sound of a drowning VW bug sound worse than the Dodge or even the Ford V-10's? Maybe you can have a "dual" exhaust system. Dual as in when in 8 cyl mode the exhaust goes through a Flowmaster and when in 4 cyl mode it goes out one of them big coffee can mufflers under the bumper. Sorry, I know I was no help.

Replying to: davethecarnut (Sep 11, 2007 10:10 pm) Actually it is worse than listening to a Hillary rant if you can imagine that. As for V10 sound, I've heard a V10 in a Viper and I was in AWE of the sound. Don't know about the Ford. I think your exhaust thoughts may have some merit. I think Gibson would do well in obtaining an engineer with that type of imagination. I don't think they have a true engineer on staff. Live and learn... I'm movin on.   Good chuckle!

Replying to: gravityprint (Sep 03, 2007 9:20 am) You do NOT have the Corsa. Borla makes the GMPP Catback sytems now and it's the Borla that requires removing the spare tire. Corsa systems do not interfere with the spare. Trust me, I am right about this.
#62 of 160 So if Borla makes the GMPP and the dealer by obyone Sep 18, 2007 (7:37 pm)
installs it, where exactly do they put the spare? Borla makes good products and Corsa is better.
