Anyone installed a Magnaflow cat back system on XLR 4.6L? I can get a new system for $1,100 vs. the higher cost of a Corsa. I was wondering if it was louder or if there were any reports of interior drone.
I've read a couple of drone reports from Magnaflow installations, though nobody has complained about the quality of the overall exhaust note or construction. Corsa systems can be had for $1500 and free shipping, which isn't too much more than the $1100 you're looking at. My Corsa sounds/looks great, and was easy to install.
