Ronin RX-LS Swap Headers!
« on: February 14, 2018, 01:26:57 AM »
Coming Soon:

Ronin RX-LS swap headers...  We're finally launching the long tube headers we've always wanted ourselves.  This has been in the works for quite some time now, but we're close enough that we wanted to share the details and start putting together a list of interested folks.  As per our usual we're planning to offer hook-ups to those who jump in first and are willing to give us feedback.

Basics:
-All stainless long tube headers.  We're not even bothering with mild.
-Made in the USA (Yes even the tubing.  This is both because America F-yeah and because we found it bends nicer than the imported stuff)
-Only one configuration planned for now
-1 7/8" mandrel bent primaries
-1/2" flanges
-Quasi Merge collectors w/ choke trumpeting back to 3" exit.
-02 bungs (duh)
-V band flanges with interlocking features (male female) 
-Intended to fit FC, FD, and RX8

Note on the quasi-merge collectors.  From a flow perspective these are effectively identical to slip-on merge collectors.  The difference is that we wanted to avoid the slip as it offers potential for leakage which can make tuning a PITA (ask me how I know).  These will use a full merge spike with a deep drawn stamped exterior, that lets us weld the spike first then burn them in all the way around.

Design...  well there aren't infinite options since we have specific length targets in mind and we need to keep these tucked tight.  Expect it to be clean.  Don't expect a bowl of spaghetti.  We will check triple check the spark plug clearances, we promise!  That said, we won't just be copying the existing players on the market either.  We plan to end up a bit longer than JTRs (and the Spooling knock offs) after all who doesn't want an extra inch or two?  This will shift the tuned RPM slightly lower and broaden the sweet spot for HP at the top of the RPM band. 

Joel's headers are the starting point but we have several tweaks planned.

So here's the deal.  Anyone who's familiar with Ronin knows that Mike and I are perfectionists.  We want these to be perfect and if they're not we're going to keep tweaking them until they are.  That's just how we roll.  We already have a test chassis for FC, FD, and RX8 in place, but we're looking for 5 possibly 6 testers covering 1) as broad a spectrum of available mounting kits as we can.  2) RHD vehicles we can test since we want to check that for our international folks.

We're gonna make you a screaming deal to be sure we have our production sorted.  First articles will be kicking off shortly.  Best guess that puts us a couple months out until we're ready to start shipping.  We're going to prioritize folks who can get these into cars first rather than just first-come first-served.  That said, if you're one of the first 5-6 selected we're gonna sell you your headers for $700!  You can't find that deal used, much less in stainless w/ merges.

The rub...  You're going to owe us a write up with pics and details.  Since we've learned the hard way that life happens and not everyone follows through, this will be charged as $1000 with a $300 refund given when you hold up your end.  Best guess shipping should run about $50.

The guarantee.  If you're not satisfied with fitment we'll take them back and put your $700 toward a set of the second batch where in we'll have solved whatever is was you were concerned about.  We're optimistic that we won't need changes given the effort we're putting into to fixtures and verification, but there it is.

Who'd like to be on the list for the first ones?

While we're here, what feedback on existing header options do you have?  What did you like?  What drove you crazy?  We've been around these things for quite some time, but if their are specifics you're looking for now's the time to let your desires be known.

Do you have any installed pictures?  How is overall clearance and ground clearance?

Its cool that you guys are gonna start making headers, and I totally agree that longer collector length is better.

If you need fitment testing Mike, let me know. I'll need my X pipe modified to make them actually work, but that is no big deal.

If the ground clearance is as good as my Spoolin headers I am in. Also not too close to the floor boards is a good thing too.

This is a down the road thing, but I plan on engine dynoing my engine next build. I have spoolin merge 1 7/8Ē to benchmark against if you want.

Any possibility of a 2" primary setup for a ls7?

Thanks

Iím pretty freaking excited for these.  Iím already collecting Ronin parts for my swap and these will just ice the cake.  I am sad I canít capitalize on this deal, but I canít swap any faster than I already am, hahaha.

I'm really skeptical if these will fit, but I'd probably swap my spoolin 1 7/8" for 2" primary for my stroker that I want to spin 7500.

Oh man, I already committed to a Sikky Manufacturing mid-length setup that required a bit of "persuasion" on the passenger side to clear the subframe  :'(

Would longtubes that fit FCs and FDs even work with the Sikky kit?
