What?! I cant hear you! lol.
#5 you will lose some hearing!
I'm 21, and just from driving tractors (farmed since i was 14), to driving my trans am (see below) and driving a dirt circle car (open headers on a 400+ hp engine, at 7000 rpm) I've lost hearing. Doc says about 35%! Mufflers!!!!!!!
The exhaust on my daily driven car is...
headers-1 foot 3 inch pipe-12 inch glasspack-2 more foot of pipe-turndown
Its REALLY...REALLY loud! And its REALLY cool!!! ...for the first week...then it got OLD!!
I like volume, but it has to sound smooth, not all crackly and raspy like with a straight pipe.
my opinion, don't do it...it may sound like a good idea, but it end up being really annoying!
