So, I've been searching high and low for some aftermarket headers for the UCF10. Obviously, with such a small following of the LS400 in performance markets, this is few and far between. I've ran past a set on EBay from Australia, for 600$. Not a bad deal. I was wondering if anyone else found any others?

I'm looking to get some unequal length headers, to get a gnarly growl out of the 1U.

 

lol good luck.

search is your friend, afaik none are made to be bolt-on. the ones you speak of out of AUS won't fit right as they're made for RHD cars usually.

 

Tundra headers fit the motor but not sure if they would fit in the ucf10 bay. Ask in the 1uzfe facebook group, those guys have the answers you seek!

Think member usoff has headers on his 10 but they may be custom can't remember.

 

I do have headers but they are a discontinued set of S&S headers. They did bolt right when I got them, but I welded new exhaust flanges on them.

 

This is most dissatisfying news.. I'll have to look into the tundra headers, though I think they aren't easy on the wallet..

 

Ive been wanting to see if these will fit with or without modification.

2UZ, 1UZ the same exhaust pattern?

 

Flange pattern is the same, but you may run into clearance issues, I'm not sure.

 

the 2uz headers will not come even close to working on an LS properly. The flange fits and that's about it, if you can even get them bolted on.

All these listed are knock-offs of the old S&S 2uz headers by the way. not the best quality

 

^ OK so then what about SC headers?

 

none will bolt-on and work, SC headers will at the very least require relocated cats and exhaust-work, likely more.

 

how about the performance benefit of said headers, or any headers? i'm sure there is some benefit but i suspect the overall cost is not worth the trouble, unless cost is not an issue.
