Swapped mine out yesterday at lunch. No real big differences noted though. It does sound a bit... deeper, the drone is still there around 2500-3k rpms (ish) but it's not as loud as before. I did notice a change in tone at WOT though that's hard to describe but...
. It's almost like I can hear the exhaust gases flowing through the pipe now (like I said, hard to describe, lol).
All in all, if it gives me a few hp then I'd say it's a decent exhaust mod for the price. I do have to warn folks though... those aluminum bolts that hold the front of the chassis brace on WILL shear off if you're not careful (
).
