New Dynomax VT Exhaust

When I connected them directly to the headers to test them there was some clanging of the valves at idle. I have a pretty healthy hydraulic roller cam with 236/242 duration, so the idle is choppy. Once I got the whole system installed with the H pipe, I do not hear any clanging or rattling at all. Can't say about longevity yet, but Daves69 seems to have had good luck on a daily driver. Given that, and with the amount mine gets driven, they should last a long time
