will i lose any low-end with straight-thru mufflers(ultra flo,magnaflow)?

[vladie22]

since ultra-flo's and magnaflows are a straight thru design , will i lose any low end torque by welding them on to my stock pipes ? i'm not sure if the lack of back pressure will hurt me . i still have the stock h-pipe .

You still have plenty of backpressure if you are just changing the mufflers. Even if you did lose torque it would only be like 1 or 2 ft. lbs.
