Well i got my slp lm1 to day and see how they are just straight pipes, so i was wondering if i would have any back pressure in my exhaust if i have no cats as well , i am haveing pcv problems and was wanting to put crank case evccuationkit on my car but they say it will not work with exhaust back pressure.

No cats and SLP LM 1's....you won't have much backpressure, my friend.

get a new pcv valve then. you dont need a crank case evac. set up unless its like a full race motor. You wont see a gain in power. Why would you need exaust back pressure for it anyway? I am assuming that you are talking about a vaccum pump.

89lx, it says that u can not have any backpressure or they evac system will not work , it works off ur exhaust

almost 500rwhp.. sounds like a race motor to me

should have got the LM2's i think they come with mufflers

Not much more than straight pipes, I would imagine.....

are the SLP LM1's legal? ya i know its a stupid question but since they are pretty much straight pipes wouldn't that affect emmissions or whatever? just wondering cause when i get my car i'll probably slap them on it but i have to worry about emmissions.
