#50 of 160 Hmmm by obyone Aug 06, 2007 (6:57 pm)
"Corsa performance has engineered a true performance system"   been saying that around these parts for years regarding GM trucks and Corsa. The thing is Corsa is expensive. You could buy a bunch of Gibson and Flows for the price of a S/S Corsa. Guess you get what you pay for. Replies to this message: schlog (Aug 06, 2007 7:05 pm)

Replying to: obyone (Aug 06, 2007 6:57 pm) Actually, for $270.00 more I could have retained my sanity and family harmony. You'd think grown men would learn to quit messing with things, I'm getting there quickly. Looking back, I'd have left stock alone. Looking forward, Corsa is hopefully going to be my solution as I have seen and heard their system. Our local junkyard wanted to charge me $700.00 for a salvage system from Indiana. I think not, based primarily on it being "used" to me. When will I ever learn?
#52 of 160 I lucked out with the Corsa for my Denali by obyone Aug 06, 2007 (7:12 pm)
Having gone the Gibson route with the Silverado, I figure I'd give Corsa a try since it was GM approved. Didn't want to pay full retail plus shipping so I ventured onto ebay. Found a seller who just removed it after two months on his Denali. Asked him why he removed it and he said that the wife traded the Denali for a Range Rover and he wasn't about to give the Corsa with the Denali not after having it installed for only two months.   So his loss became my gain as I picked it up for $350 + $75 shipping. And Corsa doesn't resonate but is a little loud on start up.   Did you try pricing a stock system from the dealer? Just curious. Replies to this message: schlog (Aug 06, 2007 7:20 pm)

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.

#55 of 160 flowmast-error by donavin1976 Aug 15, 2007 (6:36 pm)
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) Actually if you buy your gas at 76 gas stations, none of your money goes to OPEC, as none of their gas comes from the middle east.

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.
