I just got a SRI for $70 and bought some silicone/aluminium pipe from Super Cheap for $105 to extend it into my bumper. With some clamps it came to $185 total.

Sounds nice...if it goes harder I don't really notice it like you do with most small mods on any car, but it can't hurt.


Don't buy Injen or anything pre-fab for your SOHC.
