let me know if you want more info...

so in sense of bang for bucks.. its a no go?

its because im still deciding to go with the xforce exhaust or not, and just wanted more feedback on the headers.

still tossing between the xforce cat-back or a customly made up one with just 1 muffler.

price wise.. the custom one should cost me about $300, and the xforce is roughly $500-$600 (trade price)

hey okapi, u wouldnt happen to have a clip of your exhaust?
just wanting to know what the xforce sounds like.. because it seems like the custom one sounds heaps beefy.. i dont mind the loudness of the exhaust tone. as long as it sounds good/tough!
