Has anyone running flowtech headers looked into their collector and see their primaries. When I looked I saw that all my primaries curve in on themselves and some were jagged looking. It looks to me like this would be a huge restriction. I plan on soon taking a dremel and grinding the ends of the primaries smooth. Anyone else notice this?

 

A bunch of people have had those. They are most definatly not good compared to other headers. How much of a restriction is not that much unless you are running a big cam or a larger engine.

I would most definatly fix them up if I were you.

Yep..
Those of us on a budget have to deal with this kind of stuff... The primaries on my Pacesetters weren't too bad, but they weren't the cleanest either.

 

Thanks for the replies, glad to see I'm not the only one. Wasn't sure if I just got one of the first unrefined batches of headers. Can't wait for the day to slap on some QTP stainless headers. Until then I'm definately going to dremel them smooth.
