I put on dual, slip on's from LAC. I realy like them. The price is around 400 and they sound great. I do need to jet the Teryx but it was OK for the first week of fun (37.5 hrs). They will backfire a little, but boy did it take the heat off the rear bed. That alone was worth the price. However I don't have the tilt bed, and I don't think the bed will raise without hitting the exhaust. I will contact LAC and see if they have a solution to this problem. If you are not going to raise the bed they are a real head turner. I pulled up to a mud hole in WV. and it was like hanging a 12 pack in front of rednecks, they all came to see the Teryx with the pipes. Oh yea I forgot to mention that I also installed the Dynotec CDI. Terra Cross with 14" ITP wheels. and some other goodies.
