Anybody who has been around here awhile has heard of the legendary equal length, long tube, stainless headers by Sean Hyland Motorsports. Although no longer in production, SHM informed me that we could get them made if we had 15 buyers.
If I understand this correctly, long tube headers broaden the powerband by boosting torque at lower RPM; whereas, shorty headers simply help high RPM breathing.
Yes, I've heard from Andy W that installation is a PITA. I'd like to see this product made available again, if it is superior to the MSDS headers. Anybody have a dyno with SHM?
