Hey there!
I apologize for the late response, been out of the office testing a bit lately.
As many may know, the exhausts for the TRX90 is limited and many may seem very similar. We do however, offer the following:
-304L Stainless Steel mandrel bent tubing with CNC machined 6061-T6 Aluminum Flange
-Robust MIG welded construction for header and tailpipes
-3D Laser Cut 304L Stainless Steel header heatshield (to protect riders' legs)
-CNC Machined front and end caps from 6061-T6 Aluminum
-CNC Machined 6061-T6 sturdy aluminum muffler mounting bracket
-Spark arrested and 96dBA USFS approved (removeable for cleaning)
All are exhausts are hand made here in the USA to ensure the highest quality. Although ours isn't the most inexpensive option out on the market, we do ensure the best performing and highest quality product.
Let me know if you have any other questions!
