Can you arrange for the arise bumper with your header

We visited with Bill and Zach at Delicious. We gave them one of our systems and we hope to release their numbers in the coming weeks. We also have them to thank for squeezing out a ridiculous amount of power for us that we never knew was there.

There's also one or two others systems here in California kicking around. They're being tested by a top quality speed shop and rumor has it they may be available for purchase in the states real soon

To clarify the "contact issue"-
If your motor mounts are in good condition, there is no issue.
If you have stiffer aftermarket mounts, there is no issue.
If your motor mounts are worn or cracked, there *could* be potential contact.
At this point we have no plans to change the design.

Any questions feel free to ask
Happy driving
ACE Header

subbed for what delicious tuning gets out of it.

@AceHeader-MT would this fit on a RHD 86?

Of course, Our test car in Japan is RHD.

@AceHeader-MT Is there any negatives putting the O2 locations on the runners before both cylinder head pipes merge? It doesn't look like it from your dyno data but, worst case scenario, couldn't you run lean/rich on the right bank and not catch it because the ECU only has information from the left bank? If that is possible, is there any room to extend the O2 sensors to the end of the over pipe?

I really am liking this header either way and I'm waiting to see what Delicious Tuning has gotten out of this header.

I ran a set up like that for years on a different car. I never had an issue. But yes what you're saying is possible.

Any updates on tuned dyno results?

Drvortex · 03-16-2015, 04:45 PM

I checked on your website. The pic of the full exhaust looks like it has the header as well. I'm a bit confused. I'm looking into upgrading header and exhaust plus intake only. I know you don't sell intakes but do I have to get the header and exhaust or does the exhaust at $1475 include the 4-2-1? Thanks for the clarification.

We're updating website info today.

The 4-2-1 is a 2-piece long runner header.

the "OP" is part of the header and we've now put the O2 bungs there as well and can read from bank 1 or bank 2.

Any questions please feel free to pm or email

Race season seems to be in the air and most dyno guys are busy. Out of our control at this point but hope to have data for you guys soon.

burdickjp · 03-16-2015, 11:09 PM

I'd like to see O2 bungs not at merges. They're better all the way downstream after the choke of the 2-1 section. Include wiring extensions if you must, but merges aren't happy places for them.
Just my 2 cents.

To counter that, I think you're doing an AWESOME thing by offering a true long runner manifold.
