The ATS surp.system is very nice and very well thought out.the carbon fiber valve covers are also very nice.I think it was Shane we spoke to today.He said there price point on the lsx surp. system was going to cost about 2900.00 and the valve covers around 400.00 both are very nice pieces. There pricing is right in line with some of the other Mfg. Pricing.I dont think you will be disappointed in the parts.Tim
