    oh come on your 60 sucks donkey balls in the first place and i would blame any difference you see in 60' due to tire spin. On top of that your compairing your numbers from open exhaust to true duals. Did you have 2 cut outs or just one after the i pipe, that would be a big difference! Many factors in what you experienced that could skew the numbers. Show me 10 runs of each and then compair. Hell i could show you time slips where i dead hooked vs me chirping the tires for a split second on launch and i lost a crap load of time... Again i would love to see links proving your claims.

    backpressure= tq
    no backpressure= hp

    no backpressure will not burn your valves and yes having too much backpressure can make your car run like shit and possible cause damage.

    There's really nothing more to it...

    so, what's a good 60ft for a completely stock automatic car then?

    sorry, no tire spin. wish there was.

    here, get back with me once you are done reading.

    i actually compared completely stock exhaust to open cutout with stock muffler to bassani tru-dual exhaust.

    the cutout i had was in the stock exhaust system. guess you missed that.

    lost time meaning you had lower ETs with the chirp, or slower time?
