Do the AFE cats scrape? Most aftermarket cats in the primary location scrape since they are round and not pancake like OEM.
How much volume does the 300 cell + resonated midpipe add over stock? I’d love to squeeze any amount of power out of the midpipes but I haven’t yet since I have a super low tolerance for smell and noise.
