"Here at Brullen Exhaust Systems Inc., we strive to offer our customers the highest quality exhaust products possible. Our products are manufactured using 304 stainless steel, featuring a fully welded construction. This, combined with continuous quality control inspections, provides products which surpass the expectations of our customers.

At Brullen Exhaust we have two types of performance mufflers to meet your needs. The original straight-thru design, that delivers maximum flow and performance and, a chambered muffler, that delivers great performance (compared to stock) with a quieter sound. Both of these mufflers give you the performance you want with that unmistakable deep throaty sound that Brullen is famous for. Combine these mufflers with mandrel bent 304 stainless steel tubing and you end up with the very best sounding and fitting Cat-Back systems in the market!

All Brullen mufflers come painted in black (standard), for a small cost any muffler can be polished. Call dealer for details."
