    i would expect to hear that from a vtech owner.
    again thats dragracing. low end doesnt matter there. F1s are fast race cars, but their low end sucks.

    is nascar drag racing?
    nascar uses products from hooker, magnaflow and other exhaust companies.

    im guessing at 18 years old you have never driven an F1 car. me at 38 and ive never driven one either.
    how do you know if the low end sucks?
    those cars can do 0-60 in under 4 seconds.how can that low end suck?

    ^ for a car that light, thats not that great. and compared to their top end they have no power. but nascar is the same. they are constantly at top end. why bother doing anything with low, they start at a rolling start and are constantly going at it? a road car is a lot different than a race car.

    who races for 50-100 feet?
    if a car was to lose any tq, thats where it would be lost and quickly made up afterwards.

    also if you worry that a car will be sluggish off the line, for a 6 speed car you get a taller gear or a stall converter for a automatic.

    people do above all the time when they cam cars.

    at 50 feet even a stock car is going to be in the 3000 rpm band atleast.
    You totally missed my point, yet it doesn't suprise me at all.

    maybe everybody thats worried about back pressure should put their stock exhaust back on this way 'their" car wont feel sluggish off the line.

    Yes, the 80 series Flowmaster sounds great. That's what I had before the B&B, and I loved it.

    im no talking about racing. just saying its not a myth. i you are driving your car and shifting at 2000 with a full exhaust or with just headers or none at all, the car would have a lot more power with the exhaust. half the point in the v8 in our cars is o have power everywhere, and even at small throttle. porsche and ferrari have much smaller engines than ours but normal driving like this they seem to have as much power as ours because of their variable induction/exhaust.

    your right backpressure is not a myth..its a myth that you need backpressure to make torque. How bought you start to disprove that response i posted since all these "you need a little backpressure" comments...start to tear that post apart the way it tore apart the backpressure myth.

    I'M NOT TALKING ABOUT (ALL OUT DRAGSTER) !! I PERSONALY THINK A SMALL AMOUNT OF BACK PRESSURE IS GOOD FOR LOW END .
    THAT BEING SAID - I WAS RESPONDING TO DIFFERENT MUFFLERS
    WHEN I SAID YOU COULD REMOVE THE MUFFLER COMPLETLY AND SHOULDENT MAKE MUCH DIFFERENCE
    GOING FROM HEDDER,MANIFOLD WHATEVER THROUGH Y-PIPE TO REAR AXLE SHOULD BE PLENTY OF RESTRICTION STILL!!

    EVERY ENGINE is designed to bring in as much as possible mix combust and expell as fast as possible....so how is drag..of any sort a positive ?? how is a little bacjpressure good..if bp makes torque then why wouldnt alot of bp make alot of torque? im sorry but changing the exhaust of any car changes the scavaging points of the exhaust and therefore changes the power band
