is it a stock motor.... if so the bigger is bette rule isn't always the case, you should have went equal length shorties into a off road midpipe to cat back (all 2 1/4" or 2 1/2" in diameter).

no, but a set ofHeads, Cam, Upper/Lower Intake, EGR Plate, TB, MAF,Gears, and maybe a power adder wouldsuit that exhaust... did you do a bit or research before buyingthe exhaust?

aparently not... long tubes will hurt your performance until you slap about 6-7k into your motor
