Catless H Pipe setup
Anyone running a catless down pipe such as the Magnaflow with their stock manifolds? Mine don't have the pre cats, and I'd like to do away with the stock 130k mile cats. They must be bad with that many miles by now right? I like the idea of the catless H pipe because I could always bolt the stock system back up without hacking anything. I know it is going to throw codes, but will the check engine light actually pull timing or do anything that would cause me to lose hp? I am running Borla straight's and would like to have a more free flowing and better sounding exhaust without longtubes. Thanks guys
