Sorry guys...I kind of started this re-hash of an old topic with my own purchase of new pipes for my FFR. My 351w produces 460HP and I just installed a 100 shot of nitrous for 3rd/4th gear down the lane. My old FFR sidepipes were wide open just like the baffles you folks are using on your Classic Roadsters. I loved them ! My primaries were 1 3/4" but very sloppy welds and hand made bends. These pipes were manufactured when FFR first began making 351W 4x4 headers. I recently upgraded to custom made 1 7/8" primaries. MY new side pipes contain 9 discs that are fashioned to produce a spinning velocity effect. The manufacturer of these new pipes is a NASCAR chassis sonic test certifier who also custom designs headers. He assures me the discs direct air flow in circular motion for smoother exit to the atmosphere. I responded by describing the new baffles your guys are using on your CR Cobras and my satisfaction with my old FFR open baffle design sidepipes. He then advised me the open baffled sidepipes would crush TQ on a 350HP SB Cobra. I ran very fat (74F/84R) jets on my carbed 351W and I believe my open sidepipes required that fat jetting to make power....and they did. He advised the 9 discs will make more power by producing heat and velocity in the sidepipe. So as B Compy upgrades his CR sidepipes I relayed the expert comments but still cling to my very positive experiences with my open baffled old FFR pipes. Heck, I may enjoy my equal length mandrel bent new primaries and drop the same muffler section in the side pipe that you folks are using . I fear the discs will cause flow restrictions whether they swirl the air around or not ! I am confused and I rattled B Compy in the process ! I agree...running the least back presssure, straight out and jet fat for power. Apologies.
