Thread: Muffler delete/straight pipes

    Default Muffler delete/straight pipes

    hey guy just wondering if I take both mufflers off and run straight pipes from the y pipe will that be bad for my car, ie. (no backpressure?). Also how loud would it be, like will the drone be bad, would i have to put resonators in?

    any help would be nice.

    Cheers,

    I'm no expert, so not sure what negative effects it will have on the engine/power. But I'm sure it's going to sound horrible. A quality car deserves a quality exhaust.

    I had a 3" exhaust from turbo to tip with no muffling... It was super loud and actually sounded very nice on full noise, but at cruising speed it droned like a bitch! One benefit of straight pipe is flamethrower spec between shifts!

    I ended up putting in a Magnaflow rear muffler which toned it down and cut out the drone.

    If you did what you are suggesting, i can guarantee that you will:

    A) hate yourself and the droning
    B) be pulled over by the cops.

    No backpressure is good for a Turbo car, but as the others have said, it would be way too loud.

    @MPS2NV has the Corksport system. It's loud, but sounds tough. If your after noise, it's might be a good compromise. That said, the Magnaflow is a great muffler. Had one in for about 3 years. Only change I've made is a res-delete, makes it sound more gruff, pops a bit on overrun , but cold startup is loud.
