    need your opinion please

    Ok, i'm going to change my exhaust. right now i have manifolds with cats and 2.5 inch y-pipe with a cut-out exiting in a flowmaster crossflow. i am changing to stainless steel LTs with no cats, a pacesetter 3 inch y-pipe, and going to exit in a magnaflow crossflow muffler. i'm going back with cut-outs but cant decide to put 1 behind each header or just one under the right side passenger seat after the y-pipe. what do ya'll think would be better? more power? also how will the magnaflow sound compared to what i have now. Thanks

    2 cutouts right after the headers would sound killer. But you'll get a headache after a while, so good thing you can close them. Performance wise, cutouts don't do much because they eliminate too much backpressure from the engine. It needs a little backpressure to perform optimally. Some see more gains breathing through full exhaust than through a cutout. But a cutout definatley sounds meaner. As fas a sound through the whole system...I don't know. I have a flowmaster catback on my car and it sounded pretty mean by itself. I threw on some pacestter LT's with Y, and the car got quieter. I don't know what happened there, but, magnaflow is a more mellow tone by itself, but sounds decent with full exhaust.

    They shouldn't...but I think they did on mine. But I COULD possibly be a little deaf now because I actually ran open headers for a few days after install. Loud as shit, let me tell you. But after driving the car for a little while, I don't think they got 'quieter', I just think it wasn't the sound I was expecting with my particular setup. Doesn't sound as mean as I hoped it would.

    But don't be discouraged about my complaint, I'm picky when it comes to my car. Pacesetters are the way to go.

    A little, but not neccessarily louder, just a deeper exhaust tone.

    The only difference is that its not breathing through a cat, that's all.

    Over a stock cat - yes, at most 5 hp
    Over a high-flow cat - not really

    I don't think but I know unless your running some bullshit it will always make more power with exhaust versus cutouts!! Why do think all the fast "door cars" run mufflers now......:slapboobies: We have ALL found that the motor makes more power that way!!
    Can NEVER go wrong with good set of boobies.
    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    I want to be able to piss some people off tho with an open cut-out and no cats. so i guess 2 would be overkill? just one under the right rear passenger seat?

    how would the new set-up i want sound compared to just my flowmaster and cut-out closed? how loud do ya'll think it will be with a cut-out open with no cats and LTs. power additions? thanks everybody

    Way too loud. If you like cutouts, then you will like that combo. Loud enough to cause a headache.

    I just did a head install on my cammed Z, I got SLP LT, ORY, and Hooker CB, and it is LOUD AS HELL now. I wouldn't want it any louder. Prolly didn't help that I took ALL the sound deadening and insulation crap out, not to mention about 100 or more pounds of other sh*t.

    It wakes up the neighborhood now, but JESUS does it sound delicious. Makes my 01 Cobra with off-road exhaust sound wimpy. And that MF sounded GOOD.

    I crunk it up with just the SLP LT's and nothing else, and it sounded like an open header track-ready Big Block Chevelle. WAY TOO LOUD man.

    You think you could get a sound clip of that setup? I'm considering replacing my flowmaster (came with car) with LM's again, but this time I have LT's and Y. The car is a tad too quiet and isn't producing the sound I want. But I'm nervous about running this setup because I don't want overkill. Or I might just replace the muffler...thanks.
