Long downpipe (replaces both upper and lower downpipes/cats), Mazdaspeed3 (fits 2007 through 2013, 3" stainless, high flow and full 3" throughout.

Deletes the restrictive donut gasket found in many other designs and promotes full 3" flow throughout. All CNC machined flanges, 304 stainless tubing, and TIG welded construction. Fully built in the USA and comes with the ATP Limited Lifetime Warranty!

Please Note: In order to effectively delete that restrictive factory style donut gasket (in order to promote maximum possible flow), we supply these parts (with the downpipe) to be installed in this order: 
1X Thick Flat gasket supplied goes between the rear of the ATP downpipe and the thin (sheetmetal) flange on the catback exhaust. 
2X 10mm studs to join the two flanges. 
4X 10mm locknuts to go to ends of both studs 
2X Regular 10mm washers go on the downpipe side 
2X Laser cut "V" washers go behind the thin flange on the catback side to make it more rigid
