    Putting this out there to the guys who have more than average experience with twins. Is it fair to say that its less common to have huge backpressure problems when you run twin turbos. I understand that theirs many factors that affect backpressure. This is Not a drag car.

    My setup is from the 1999-2001 timeframe at TDC Turbo Driven Concepts-out of Hialeah FL.

    351 Windsor motor, mild cam, Twin T66's Turbonetics-P trim with .58 a/r turbine on-center housings, 1-5/8" headers, twin 3" downpipes, 2 1/2" cold side, 3" A/A intercooler and 3" into t/body. Also I run dual 3" exhaust,no cats,crossover,x pipe and full 3" tailpipes.

    Mufflers are the Dynomax Super Turbo. Can these mufflers be extremely restrictive, b/c they were inexpensive? Noticed on some similar threads that guys had data supporting Magnaflow mufflers were much Less restrictive then other brands. Thanks for your help and dealing with this long thread.
