Now I just need to change spark plugs (ordered plugs with a smaller gap than stock) and order a tune (which comes with a 10 degree cooler t-stat @170). What do you guys think of running a cooler t-stat, I've heard some concern that it reduces the longevity of an engine.

Oh and the welds on these look very well done, a guy here at work that knows his stuff commented on them.

SHO Downpipes; They are here!
