I have been wanting to change out my exhaust for a while now and finally bit the bullet. I chose the Stillen dual rear exit, it seems to fit my needs and wants. So far I am impressed with thier service. I sent them two emails with questions before I ordered and got responses to both with 12 hours. I just got a shipping confirmation less than 12 hours after ordering from their web site. You can not ask for better. CUSTOMER SERVICE IS ALIVE I TELL YA....ALIVE!!!!! Wheh, that feels better.
