I just purchased a 2010 camaro! I want to take it and get aftermarket exhaust,suspension,a supercharger,ect. I know the big 3 companies are Lingenfelter,Hennesey and Callaway. I have done some comparisions and they seem pretty good in terms of products used. I have not personally delt with any of these companies and want to know if one is far superior or inferior to the others in thems of quality,fit and finish,customer service, ect. I have been waiting a long time for this and want to make the right choice. thanks
