I was just wondering if anyone around here has j's parts on their car? Im interested in buying a J's header and would like to know how that performs. Any info would be appreciated, thanks!

 

I heard its a good piece

 

I would pick it over mugen and amuse
which are in my opinion the closest competitors

 

Why?

 

I try not to ride with him. He smells.

 

I don't ride with J's.

 

Doesn't Muff have a J's header? Ask him

 

^ is he even on this board any more?

 

The "wall" of the Js is, if i remember correctly, 1mm thinner than Mugen (same as amuse, however). This allows the tubing be of greater diameter, and also allows the unit to be lighter.

The amuse's design is similar to the mugen. The J's has a newer design which yields more power gains than both (I think particularly in the high end range).

Having said that, the quality of the mugen and amuse are better than the J's. The welding on the J's I must say is a bit iffy, but I am particularly anal about that kind of stuff.

 

Hehe... you said unit
