AERO 4040XL Before & After

[Buzzy]

This is for those who may be trying to figure out what to do with your exhaust set-up.
I installed the Aero 4040XL and deleted the Cat and stock Muffler so basically it is straight piped with the Aero in place of the muffler. This is my truck before the Lift and new shoes!

Watch the whole thing, it is a before and after from stock exhaust and then with the Aero.

My dads got nothing but straight pipes on his 03 ctd, nothing but raw loud badassness. Much louder than the aero, but that aero has a great deep sound.
