anyone have any experience with a Strup header, what kind of numbers they make, etc.?

 

essentially a DC header, the quality is a little less than DC but you get the Idea

 

Who???

 

don, you've never heard of strup? One of DCs sales managers went out on his own a few years back and made his own. Kinda like the Blox situation.

 

Oh yeah.... They stole our Q35 header design too... Oh well...

 

I assume you are talking about the imitation JDM ITR 4-1. I picked up a stainless steel one for $150 bux on ebay a year or so ago... I still haven't installed it so i dont know how well the holes on the flange match up with the head but this is what i have noticed.

The runners are welded on top of the flange and it isnt a smooth transition..I spent over an hour grinding material off the backside of the flange (not the head side) to make a smooth(er) transition from flange to runner.

The collector isnt that great either but hell for $150...i cant complain. you get what u pay for


1 decent thing about this header is the runners are staggered so they dont meet up as a perfect square and give it a lil bit of clearance (compared to a 4-1 with the runners stacked directly on top of each other....I was thinking about putting a new collector on it but it would have to be staggered as well

 

Overall, I think Strup is decent header for the price. It performs well, similar to the DC sports header with a lower price tag. Here are some pics. B-series B18C. Part #A11105
