Exhaust Modifications

[Rare Iron]

Thieleng, the ones you ordered were without packing. Longer packed versions would be even quieter & would perform just as well. I loved Stephen's description of grabbing second gear - VERY impressive!

Thanks, -Eric

Jim,

Is your 560 RWHP before or after the new sidepipes/headers?

Thanks for the correction, I should have checked, the pipes are still out being powder coated, it is going to be 65 degrees here today, nice day for a drive, I need to get the powder coating people in gear so that I can go out and wake up the neighborhood
