Header Collector Extensions: Drag Strip Tuning

12many said
From everything I’ve read these mufflers won’t cost much if any power over an open exhaust. You’re mounting them to the extensions and dumping, minimal pipe right? My system is shorter than most that dump at the axle View attachment 1715813333 but I remove both assemblies and just run the extensions (saves about 40 lbs total) at the track. Interested in the gains if any from optimizing the extensions on anyone’s setup. Have you mounted the mufflers yet and had a chance to hear them??

My s bends look very similar to yours. I do have those mounted. Then I have 54 inch of straight pipe, with the mufflers before the axle and turn downs. I have not got them fully mounted. Was waiting on hangars. I did slip them on with it running. It for sure took some cackle out of it. I'm sure it'll sound better with it sealed and clamped.
