250Cup/SE ROAD Exhaust System
I've performed an autopsy on the big/heavy factory system - easy to see why this car needs an exhaust that makes it sound like it looks!
This 8"dia (203mm) system gives a great sportscar exhaust note - really suits the car. There is no dronnnnnne with the 2bular exhaust - it was designed specifically for the tuned 250Cup motor. I've placed the big round tailpipe jusssssst so. On the SE models, you need to bring the tailpipe right back as the different diffuser doesn't "work" with the Cup tailpipe!
IF YOU WANT A QUIETER SYSTEM FOR LONG JOURNEYS OR JUST BETTER NOISE-CONTROL - SELECT THE "H1 CHAMBER" IN THE BOX BELOW. THIS HAS ONE HELMHOLTZ CHAMBER AT THE ENTRANCE TO THE SILENCER TO HELP REDUCE NOISE BY APPROX 5dbs. YOU CAN SEE THE INTERNAL SPOT-WELD MARKINGS ON THE SILENCER SKIN.
I can build you a smaller, noisier 7"diameter system - but please contact me first!
Track/Race use: see the H1 Re-Packable exhaust page for details.
