    Well the front 2 o2's are what control A/F mixture (lean/richness), not the rear o2's so that to me doesn't make too much sense. Sounds like you had another issue.

    The rear 02s have nothing to do with the A/F ratio. Welcome aboard here, I'm in Crofton Md.

    At this point I had spent $2K with them....
    It was an oil pump. I went to hand thread the bolt that holds the oil pickup tube to the pump.....the threads literally just fell out. I NEVER had a tool on that bolt.
    Yeah....fuck SLP and all their overpriced shit.
    I dont know, to each there own. I Respect your decision though, especially if they acted like that.

    After hearing the borla and looking at that car, I can not see how anyone would want to put that on their car. He lied about it, kinda made me mad but oh well. I'm sticking with SLP lM II, yeah ground clearance might be bad but I'll just not take hills at 60 and stick with the 01 with ten k. Borla is overpriced in my opinion.. I've had nothing but goodluck with SLP but can see where their reps would get defensive.

    If you went rich running no rear O2's......your tuner sucks. Or something else threw it out of wack.
    If the SLP MAF gained performance....I do not doubt this. But it also sent it into a lean state making that power. Not a safe performance gain.....willing to throw out a bet is was pinging once in a while which could create damage to the motor.

    There's nothing wrong with the clearance of the loudmouth, I have it with Lts(not slp lts ) and a y pipe and I have not had any clearance issues. I personally don't like the magnaflow system either but to each their own.

    I'll youtube you now and see how it sounds =), and I never really had a problem either with clearance except if you went fast over hills you would hear a small scape sound which broke my heart every 3 times it did it. I had the Slp MAF also, never had a problem with it and it was on my old WS6 for a while, I actually put 20k with it on and I;m sure it was on it before I bought the car, again it had the ls6 motor but you never know, could of caused problem in the near future, but the life of my baby was cut short when a lady hit me head on.

    SLP makes a lot of HP claims. Key word here is "claims"

    I gained 10 RWHP when I had my Borla on.





    See how easy that was to claim it.

    After driving a car with this "good" Borla exhaust on it with only 19k miles, the borla seemed to take away at least 20 rwhp. Or the car was beat the crap out of with only 19k miles.

    I am not totally positive but I believe this sums it up:

    -More expensive
    -Quieter

    I haven't heard it in person but on clips it didn't sound that good. Yes I know clips don't do the sound justice but compared to the LM on sound clips it sounded weak to me.
