I've decided to go with the LaBree Motorsports DP's. I just cannot justify to myself spending an extra 1000.00 or whatever it is for SP downpipes. I'm sure the performance gains would be there. Scott sounded very excited when I spoke to him. But the 1000.00 can be put towards something else for now. Perhaps in the future if plans change I'll go with SP DP's.. but for now... I just dont have the cash...
