HKS Super Manifold vs Catless UEL

I don't know what everyone's hardon for ACE is... Yes it's best header on the market but without a custom tune it's average at best. Plenty of UEL headers who make power, remove the dip, work pretty damn well out of the box with OFT and give you a nice rumble... All for less than the ace. I am just sick of basically everyone discounting every other header. There is no question that a solid 4-2-1 desgin is the best for for removing the dip and getting more power up top vs UEL... Sometimes I just shake my head. IMO the best combo is a used OFT and gruppie UEL header( which is a copy of the tomie header) just way cheaper.

But plenty of good manufacturers that are not ACE

JDL
Tomie
HKS(expensive)
P-tunning
Gruppie

It all depends on your goals and what you want to spend..

OFT just adds some drivability. Not much power, even with a header. Also it seems like OFT has mostly moved on from this platform. But yeah, used is always a good value if the header hasn't already failed.

Agreed.
I don't understand the insane hype either. I know CSG and plenty of others shove it down people's throats all the time. No disrespect to them. But I get tired of them saying, "but if you take an overpipe into account with any other header it's the same price." No. No it is not. lol

Most headers perform roughly in the same margin as each other give or take a few horses. I get the feeling OP isn't going for max performance either if he's looking at an UEL header. So whichever one he chooses, I'm sure will be just fine.

Yeah I’m not staying NA either. The sound will be nice but once I supercharge it, it won’t matter too much. If I can get 300ish to the wheels I’ll be happy.

I beg to differ. Stage 2 removes the dip almost 100% and it's the gains under the curve not top end whp. Also the ability to run e85. It may not be substantial but it's measurable.

E85 and you will have no problem with almost any kit

One station 5 miles away from the crib. The rest are over 30miles. So I guess I lucked out. But I’m going to flex fuel it to be smart.

I disagree. As someone who went from a JDL UEL with OFT stage 2 back to stock exhaust and tune very recently, there is a huge difference in power.

Shiv does seem to have moved on but he left behind a good base that a number of forum members have built from.

Read up on header design and do alot more research before thinking about any brand of UEL header.

If the runners are not equal length the header design is flawed

Opinions may vary

Physics doesn't

I think UELs are popular due to:
1. Some people prefer the sound
2. The cam tables work well over a range of different brands so cheaper canned tunes (OFT for instance) can be used with decent results.

Flawed is correct in absolute power terms but not in bang for buck. I know you like to sing the praises of a de-catted stock header but if you want to keep the original header so you can return the car to stock some day then a cheap uel and OFT would be a better option.

OP you won't go wrong with any of the headers you listed. Go with your gut. I really liked the JDL UEL I had but i haven't owned the other headers you've mentioned so I can't say which is best.

I hate to kick a dead dog but do you guys think I could run a stage 2 tune with the “catted” hks UEL Manifold? Like the oft one. Or maybe one from delicious.

Probably. The cat on the HKS manifold is there almost only for sound. It's so tiny, I don't think it will affect performance very much. I'd go with Delicious and then fine tune it so you can get the most out of it. The one from OFT is more for the FT86SpeedFactory and JDL catted headers, which feature actual cats.

That’s what I thought I tried to message shiv and got no reply and his recommended me go to one of their authorized dealers. But that’s going to be super pricey.

Authorized dealers? Like the HKS flash thing? I don't trust it. I'd just go with Delicious. Or... knock the cat out and then run the OFT stage 2 for UEL

of course it affects performance, even if it s small it blocks the gases... that cat negates some ign timinf particularly after 4k rpm

I know that. I'm just saying, compared to other catted headers in the UEL world, it is significantly smaller.
