flowmaster xtreme offroad muffler...
anyone ever looked at these? there diamond plate and look pretty rugged. was wonderin if they are worth it over the regular mufflers. and another question... what tubing should i use going into the muffler and out of it? i was lookin around here and i saw 2.5" alot. i want to get SI/DO w/ turndowns so that i can get dual tails later.
