SLP makes some of the best sounding and highest quality catbacks on the market....
SLP LM1s sound amazing, which is why I have them on my Mach and love them

As if you would know what they sound like? Highly doubtfull as many people do not have the resources to make their own custom catback.
Im aware of what those mufflers sound like but it can go either way, have you heard every slpcombo to justifiy each one sounding like ***? Highly HIGHLYdoubtfull.

i ordered the loudmouth II's and im going to see how they sound with the stock midpipe. Does anyone know if theres a horsepower gain by adding a mid pipe like lets say i added the midpipe after i already put the catback on, what kind of HP gain would i be looking at and what kind of overall horsepower will I gain from full exhaust and/or just my catback

i did not notice any performance gains from my lmII catback when i installed it, my car was BONE STOCK back then.

i did howevery notice alot of SOUND performance if you dont already have a heavy foot you will when you get the exhaust on.

Are the Powerflows significantly quieter than the Loudmouths, also how do the Powerflows compare to the stock exhaust's sound and resonance?

Thanks, I am in the market for an SLP system as well.
