XR-1® Collector Mufflers
This is the HOT set up in drag racing. This patented, award and race-winning product was designed to replace your current open header collector and serves as a power producing merge collector and muffler -- all in a single unit.

Made with the same patented, award and race winning flow through design as the Standard XR-1® Collector/Muffler. This muffler, however, is designed for door car applications where a Standard size Collector/Muffler is too large.

Application: Dragsters, Full chassied cars accepted in NHRA, IHRA, Hot Rod Series, Brackets, Super Chevy, NSCA. Not recommended for Dragster application.
