JK Motor Sports Header on eBay
Hi - never heard of them. I searched the web and could only find reference to JK Tyres, but nothing to do with headers.
Anyone have any insights?

I assume they "checked" around and found claims ranging from 0-20hp from other vendors and decided to pull 30+hp increase out of their **** to try and out-lie the others.

But they have a 98.7% positive feedback rating - doesn't eBay enforce honesty in all their posts and double-check each claim made so buyers get the best possible information? 
Sorry can't say that with a straight face.

The first thing I noticed is the small tubing. The tubing is significantly smaller than the port size and hence why thye have the cones going to the flange. The collector is also very questionable since there is no merge to it (just 3 tubes protruding inside). I would be very questionable to any gains from these headers. In fact, since the tubing is actually smaller than the stock header; I wouldn't be surprised if they lost HP.

1 3/4" primaries is not small! If anything they could be too large.
No way the stock peice is as large as those. I dont see the problem with these, they have nice welds, and they went for $157. Sounds like a steal to me. They may not make 30hp but they look like most 996 headers that places try and get $2000 for. Sure they may not work as well but at $157 they are certianly worth the gamble.

What do you think the port size of the heads or the diameter of the stock manifolds is? Measure both adn compare, then respond back.
