Ok, I've had the magnaflow muffler on my truck now for a year and it is driving me crazy. Mods are in sig but I am running stock manifolds and Y-pipe along with stock cats. I have frankensteined a catback system together using stainless 3.5" piping from a silverado SS (so I could use the tip and have stainless pipe) and then used the long cased Mangnaflow #: 12578 satin stainless muffler. At first it had a nice "meaty" tone to it without being raspy. Now after a year of driving it sounds nice but has developed a head splitting drone that drives me crazy. I don't want to fork out the cash for a Corsa, I want to make this system work. I have considered going with a Dynatech cone insert, but I've heard only a few reviews and all the folks that bought them seemed to be disappointed. Then someone from another site recommended I buy a CC Insert (http://www.engineceramics.com/hardpart/ccinserts.htm) and push the insert into the tailpipe and rivet it into place. Has anyone had any experience with the cc insert. I am giving this one last chance, if it doesn't work my stock cat-back is going back on.

Is it dumped or over axle. I had a 40 series flowmaster dumped and it droned its *** off. Switched to a magnaflow but ran it out just right over the axle and it was 10x better.

This is over the axle and out the side in the stock exhaust exit location.

Just keep checking eBay for a Corsa system for your truck. I got mine for less than $400 including shipping. You'll be very pleased with the Corsa.

Yeah, I know ultimately that would be the best solution at this point, but with the budget I'm on right now (remodeling the house) that isn't an option. I have $100 to spend tops to fix this right, or I am yanking it off until I can afford a corsa.

I have absolutely no drone dumped over axle, or either move the muff back some away from the cab.

Why ppl spend a lot of money on a corsa or mag when you can get much cheaper decent quality exhaust sys and not lose any performance. I admit i am partial to hooker quality, price, and sound, but what is the hype with corsa besides the stainless... not bashing, JW? Not tryin to jack the thread.
Thanks,

With the corsa you get quiet idling/cruising w/ absolutly no drone and at WOT it screams. And its a straight through muffler so great performance. I mean don't get me wrong I lucked out and bought the truck with the corsa already installed but I've had magnaflow, flowmaster on my previous 99 ecsb 5.3...Just my .02
