DEVELOPMENT: The factory Boxster / Cayman “T” tip section allows for exhaust gasses to crash into each other when coming out of the muffler before exiting the tips. This cost-cutting method creates turbulence and hurts performance. By incorporating a smooth, cast X-pipe into the rear section this allows for a more efficient flow path from the exhaust gases. A small increase in gas mileage during cruising and more power when accelerating aggressively should be expected. The casting of the interior is also smooth, without any protrusions from welds. A proper back purged weld with full penetration will most likely have some material on the backside in the X. Non-cast designs can and have failed at this point due to stress and possibly lack of proper welding techniques. We’ve made a very conscious decision to offer the most durable X solution possible with our customers in mind. We’ve also been using these X-sections with great success on our full line of Boxster / Cayman exhaust systems which are proven to perform (used on the fastest Boxster ever around Watkins Glen), and warrantied to do so on the track for life! Cast components such as this have been proven for years in OEM applications and by an aftermarket performance staple in the industry for intake plenums and throttle bodies, IPD Plenums.
CONSTRUCTION: A cast T304L stainless steel x-pipe is used for a smooth inner wall and clean “X” section for maximum flow. Choose from a number of single-wall 321 stainless tips (slash cut or straight cut) or chrome double-wall tips in a number of finishes to personalize your exhaust to your liking. Titanium single wall tips are also available and save nearly a pound of weight over stainless steel tips! Each component is rigorously quality-checked, tested in a fixture to guarantee fitment, and then foam packed to ensure it arrives in perfect condition.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! Our team will quickly work with you to resolve any questions or issues that you may have.
NOTE: The finish on the satin / brushed single wall stainless steel tips will develop a golden hue over time due to heat.
