true man., there is no way a high-flow cat would make a gain more than 5-10 over stock cat, as it definitely cant gain more than a test pipe.. well, having a NON-JDM header and NON-JDM cat-back means I cant run EuroR cat..
so... now the random tech cat is the only one in the market that is bolt on?How about Metal cat?where to get it? thanks
