Thanks for the response, all the hoses that connect to the bypass valve are tight and seem to be going to the right place. I took out the bypass valve and looked into it and tried cleaning it, there were some black chunks that came out of the valve. Can I replace the bypass valve with a blow-off valve? Is that how that works? And the exhaust is loud, I resurfaced the resonator and got new bolts, along with a new gasket, which seemed to help but it is definitely louder than stock.
