All bending is done in house with our own equipment.
All of our exhaust systems are made with 321 Stainless.
Each pipe is made from two pieces, a primary and secondary that slip fit together, there are no welded joints to crack.
All pipes slip fit into the collector as well, this along with a slip fit connection on every pipe ensures freedom of movement with virtually no chance of any stress cracking.
Both the cold air sump and 4 into 1 exhaust have proven to increase horsepower, combine them for even more HP!
We test fit all systems with an engine and cowling to ensure a good fit with ample clearance between pipes and the sides so no cowl mods are needed, the only area where modification may be required is the exit area.
