Cause its true bolt on no cutting, and it comes with a high flow cat with o2 fittings on them. Its full Stainless steel. So for the price of 800 or lower is good. Anythign above 800 i will wait till it drops
well it comes with new hi-flow cat all in stainless, warranty, reputable name professional tig welding and well ITS BAD ASS!!!!!!! Look at greddy's and thats just the price for an axle back. GOOD PRODUCT ISN'T CHEAP! and CHEAP PRODUCT ISN'T GOOD
