    Iam thinking off putting a pair of SLP Loudmouth II Bullet Mufflers, on my 04 gto. Will they be hard to put on the gto and will there be a big difference in noise. What does everyone think i should do.

    I have the LM2 system on my car, I like them, in cabin its not very loud, however from behind, they are an attn getter, cops and others....LOL....I like the sound its ALL about preference.

    I also have Headers, and a supercharger, so it will sound a bit different, but close

    I have a borla catback on my 04 gto and jba midpipes with jba headers.I like it and everyone says it sounds good but you have to put your foot in for it to really sound good to me.If I were you I would put a flowmaster catback because the price is not as much as the borla or slp.

    If I'm reading your post right, you say that you want to put a pair of SLP mufflers on? I'm assuming you want to adapt them on the stock system, not put a whole SLP system on, correct?

    If your planning on just doing the mufflers, it won't fit. The stock muffler inlet & outlet are offset. SLP's are straight thru. Plus the stock pipes are 2 1/4" and the SLP mufflers are 2 1/2".

    I put on a LM2 system w/ long tube headers. Sounds great. The way a muscle car should sound. I tried a set of SLP bullet resonators (LM1 system) those were a little to loud for my liking. They are a definite ticket getter.

    Have the resonators taken off. That'll make it louder.
