I just picked up a clutch flywheel etc etc. I'm thinking while doing those I should probably swap out headers ana y pipe also. Let me know what you guys got.
Had these Headers custom made by QTP. 1 3/4" primarys into a Tri Y collector. They were made using a BMR K Member.
Mufflex made the custom Y pipe with 3" into 4" merge.
Went 9.86 @ 134 N/A on a hydraulic 402 with them
