FT-86 SpeedFactory Catted UEL Header

That's the plan. Currently my wishlist has the Nameless resonated and catted front pipe/down pipe combo and the resonated PERRIN catback exhaust. I'm no expert but from what I've seen of the two, the Nameless should be relatively reserved, while the PERRIN catback is a little meaner. I'm hoping they work well together. Bolt this header to the top of that and bam, good match.

I'm seriously considering ordering one of these in a catless version.
If I don't have a tracking # for my items from JDL by Friday, I'll cancel and get one of these

I could be mistaken, but isn't the nameless piping 2.75" OD while the perrin cat back is either 2.5" or 3" OD? If this is the case, you are probably killing any hp you would have gained by the catless header by mismatching the diameters. If I am wrong, ignore me. XD

I hope you're wrong. That'd devastate my plan.

He is, check the nameless site. There is one system that is 2.75 inch, but it's not perrin or nameless.

Thanks for the correction!

What's the diameter of that catalytic converter compared to stock

Both are the prototype versions. Just a heads up there.

That catless piece is calling my name!
I think I just might call PayPal tomorrow and get some money back from another vendor so I can give it all to you guys

Very nice, I can't wait for the UEL catted header special emails. When will you be emailing ?

Assuming someone has a tune for an sc kit, will a new tune be needed? I'm guessing not because this is intended as a bolt on setup requiring no special tune. If that is true, then the volume changes are so miner it essentially mirrors the stock header. Thanks!

Depends on the tune. removing the front cat tends to drop EGT and allows more aggressive timing and may allow slightly adjusted cam tuning. Also if you are on a speed density tune your VE values will change due to changed efficiency of your header. It is best to speak with your tuner on the subject.

Catless one is on the website right now. 2-3 weeks before shipping is all on those.

Now is that 2-3 ACTUAL weeks... or 2-3 JDL weeks??

BTW I'm out filming interior videos of the red car right now. FT86 Catted UEL, Motiv Over Pipe, Invidia Resonated front pipe, Resonated V1.

It's definitely a unique sound. At idle you get the rumble but in the higher RPM band it smooths out. This header is only 32% unequal and someone was saying the stock header is 30% unequal so we're close there. I need to measure the borla and stock one later. The Borla is extremely unuqual which is why it rumbles all through the rev range.
