my car with the UUC TSE w/ DTM tips I purchased from

"Jon, Thanks so much for the excellent service, I absolutely love ehe exhaust! I expected it to sound great, but not this good, I am so happy. Never did I spend 600.00 and feel that it was worth every single cent. The system was swapped in just under an hour, it is so well made that everthing lined up perfectly, and no leaks! I have been singing your praises on Bimmerforums.com, and I hope that I can bring you more business in the future. It is refreshing to deal with such professionals who carry very high quality products for reasonable prices. Again, thanks so much for the amazing quality and fine service, we will definitely do business again, perhaps on a CAIS...? It's been a pleasure, J. Fischetti" - 9/03

"I just wanted to write and let you know how absolutely pleased I am with my new LLAE's. After having the Inpro's with the 2.0 LED mod and seeing the DDE's in person I know that I bought the best product available. The lights are beautiful and your installation looks perfect. I would highly recommend these to anyone looking for "angel eyes" and even people that arent. They were worth the wait and your customer service was(and is) top notch. When it is time for me to go HID I will look no further. Thank you very much! Most sincerely,D. L. Weaver" - 7/03
