Besides the sound differences would I really feel performance gains?
My last car was a Audi S4 that had many mods, the least felt was the Neuspeed aftermarket exhaust. Apparently, the stock exhaust tubing was so good, the $1500 cost of the aftermarket exhaust was just a better sound.
Is the '12 hatch exhaust system restrictive enough that an aftermarket catback would be "felt", like say going 30mph-60mph, 2nd to 3rd shift.?
Please post your personal favorites..thanks
If you've read as much as you say you have, you would have deduced that the CBE is simply a noise maker on our cars, until you hit high HP numbers as mentioned. Don't expect any gain at all from a system.
