TRD or swapped out for a different aftermarket product? I've read these are suppose to moderately improve performance, with improved horsepower. True? If so, how much? I've also read that getting an aftermarket product like flowmaster, etc, and get the same improvement, if not better, at about a third of the cost. Any input would be great. Thanks! P.s. sorry if this is in the wrong forum. I'm learning on the fly! Share Share this post on Digg Del.icio.us Technorati Twitter
