Planning on getting a 4-1 Exhaust header made for my SR20ve. I have been reading and seeing alot of different specs flying around. Is there anyone that can give me the right specs. Thanks
call up burns stainless they will give you specs if you fill out there engine sheet. it cost money upfront but they will clear it if you buy their collector.
most people will not part with there specs because the ones that are good cost alot to make.
