The other day i took off my flows after my cats and left them off. My car sounds a lot louder then before and better, but i have a question. I was wondering if i lost any power? I don't think that it would lose any power because now there is less restriction. The only problem is that it is way too loud and i want to get a straight 3" pipe so the exhaust will not be released right under my car. I don't want to leave it without exhuast though if it is losing any power. If anyone knows please tell me........thanks.
