I have a 355 with rhs pro action heads fitted with comp cams springs rockers guide plates and pushrods all matched to a comp cams 292 magnum cam pretty much stock but rebuilt bottom end edelbrock performer intake matched to the heads a holley 650 vacuum secondary. For the exhaust I have 2460 hooker headers to true dual spintech drag mufflers and it dumps about 6 inches before the rear tires I'm wondering if the exhaust is going to compliment the motor or if its overkill or what I'm open to all opinions on the matter thanks for the advice ahead of time 3" pipe btw

 

True duals with 3" exhaust is over kill. 2.5" would have been better for the true duals. Especially since you have race mufflers with little restriction.
