Put on a Dynomax slash cut double wall beveled stainless steel tip today, looks pretty sick - $30 shipped
Got a Borla ProXS muffler - $80 shipped
Had the muffler installed - $40 labor
each individually was less than 100, added up about a buck fifty. still not too bad, be less if I installed muffler myself but didn't wanna try welding up the exhaust or use clamps.
