I just installed the AMS stage one for my Evo X from AMS and I have to say I was very satisfied with the results. The gentleman I spoke with when ordering my parts was very friendly and very helpful. They even give a military discount so that's a plus when these stages can sometimes be expensive. I saw a recent thread of someone talking about an exhaust they ordered which was damaged and I just wanted to say the single tip exhaust from AMS is phenomenal. Excellent work on their part. I definitely recommend them to anyone.

 

+1 on that. I always have good conversations with them when I have ordered stuff from them. They are always pretty friendly and aren't afraid to chat it up when you ask other questions.
