If you could come up with a few more dollar's why not just look into a catless down pipe from a vendor?
OR, if you choose to go that route, save ALOT of money and just take it to an exhaust shop and have them cut the cat and u-bend out, and replace it with straight pipe.
sorry bio. also ive beeen told i will not pass inspection w.o a cat as i would like to remove that and ubend delete. cash is tight any sugestions are greatly appreciated
