2009 Racecraft 420 S MustangBy:

Just installed the SLP Loudmouth axle back system, sounds great. Installation was a little tricky as the exsisting system had a stud that had to be ground down to allow the SLP pipe to go over the forward exhaust system. Also the SLP passenger side pipe hanger rod had to be re-bent a little in order for the pipe to run straight out the back.
The driver side went on with no problem, all in all it took about 1.5 hours - only because I had to grind off the studs on the exsisting system and bend one rod.

SLP Cold Air Package, LS-1 Firebird (FlowPac) V8; 2000-2002 Cold Air induction: Performance & RisksBy:
Arqtec59Ownership:
more than 1 yearSlp's Cold Air Induction Package Kit worked great for about 12 years on my 2002 Camaro Z-28, I purchased this Camaro new in 2002 and treated the car with excellent care, 13 years out and only 39000 miles. My mods worked well till a RAINY day in May and 5" of water at 1-2 miles an hour, at 1200rpm HYDRO-LOCKED the motor.........2 rods cracked the block and it was BYE-BYE to a my ole faithful LS-1.......Hello, LS376/525 crate engine from GM. I am now configuring a similar system to the C-5 Corvette with a intake bridge and a ram horn split filter if it will fit. The SLP down duct work is not totally to blame for the death of my LS1. The air dam that smooths under car air flow was positioned with a forward angle to scavenge more air to enter the SLP duct. The duct was extended with additional sheet metal and increased efficiency by 25%..........this works fine with 02, not with H20.....that's air not water, for those of you that slept thru Chemistry. My only concern now, after paying off my creditcards 10,000.00 balance, is the positioning of this new CAI and MAF. The LS3 motor in the 525 hp asa cam version is particular to the MAF position from the TB and current opinion is 10 " away and in a straight section of tube, also the resisters in the Granatelli 85mm MAF may not communicate well with the aftermarket tuners, so I guess its HP professional tuner time. Sure hope this Bad Boy doesn't eat my 4L60E and 10 bolt rear end, but I can't wait to see the vet owners and new Camaro guys listen to that 110LSA, then I crack the electronic cutouts open, and see if these Nitto sticky tires can hold on to the road, while the other guys try to find a gear that works...............stay away from puddles.

1 month - 1 yearGreat Product that's easy to install. I noticed only a slight increase in the sound on startup but no difference while driving. The only difference while driving was some burbling on deceleration. Even swapping out the factory muffler only slightly increased the sound.
