I don't know alot about the TSX, but I think changing the CAT can be a risky thing to do, unless you know other in your area that have the same setup w/o aircare inspection problem (Vancouver still have aircare right?)
Like other people suggest. That $3xx dollars can be spent at other area to improve your car. There might be ECU flash which can take advantage of higher octane assuming that you are willing to pay for higher gas prices. IF you don't already have some good tires, then tires will make the most difference.
Not sure if that's what you are looking for, but that's just my 2 cents..! |
