You can search on here and you tube for plenty of sound clips wiuth people running any where from stock motors, cats and a muffler to all out modded motors, no cats and mufflers.

Best of luck, but all my money is on Magnaflow.
i want magnaflow but they dont seem to have what i want....

i realized none of the guys on this forum install corsa well maybe just a few.. maybe cause it costs alot , u guys wont believe how much corsa catbacks cost over here damn.. the cheapest u could find is around 1700$~

i would recommend a 20inch+ magnaflow maybe a 22 imo it would sound amazing with headers or without but thats just me

My 22" magnaflow on stock manifolds was way too quiet for me. Wonder how much LT's would have woke it up?

Got the 14909 magnaflow finished up tonight and left the stock resonator in place. Sounds beefier at idle, can hear it while accelerating once it hit od from 65-90 can barely tell it's a bit louder than stock. At WOT definitely has a very nice tone and sound to it.

I am contemplating experimenting with removing the resonator to see what it will do but right now I have zero drone. Does anyone have this muffler with full cats intact and the resonator removed.

Congrats on your decision.

Hope some one has a vid of what you're asking for, I don't think it will change all that much with just the resonator gone.

Im scared to play with it too much. My other truck had a cammed 6.0 and with the muffler alone it would rattle change in the ashtray and cupholder while driving. I had to go back and do a magnaflow resonator behind it to shut it up enough to make it tolerable to drive.

You should leave it as it is now, the resonator does not hurt performance at all and taking it out will likely introduce drown.

I put the offset at the front and center at the rear. Only had to add about six inches of pipe. I pulled the tailpipe out and tweaked it over a bit in the pipe bender to square the tip up back underneath the rear bumper to compensate for moving the tail pipe over at the muffler end. I finished the tailpipe with a gm performance parts stock tip. I'll try and get a idle vid up late sunday or monday. Took about an hour and a half start to finish
