I bought a J-TEC rap around for my DL-50 back in 2007. I used it for one season and the down tubes cracked out of the can. So I put it on the shelf and kind of forgot about it. Well about a month ago I started bulding a slick 540 and I wanted a pitts. So I emailed J-TEC telling them my story about the muffler and its cracks. They told me that I bought it a long time ago but send it to them and they will see what they could do. Well, they got it and said they could and would fix it. I thought that was amazing since I bought it so long ago. I also told them that I wanted a slick muffler and that I didn't have a plane for the muffler they were fixing for me. Then they said that instead of fixing my old muffler, how about they just give me half off a slick muffler instead. Because that is the muffler I wanted in the first place. So I got a brand new Slick pitts for half price!! The guys at J-TEC are the best guys to do buisness with. I am very happy with how I was treated. And they have a Raving costomer for life. THANKS J-TEC. Keep up the good work.
