I'm still working with the admin here to discuss forum sponsorship and a vendor account, but there has been some interest in what we're working on for the XKR, so I figured I'd post up some photos and details of the products we have in the works as well as the items we're testing out on our local customer's 2000 XKR.

Stainless Downpipes (200 Cell Catalyst, 300 Cell Catalyst or straight track pipe).

At this point we've run tested our first set of 200 Cell high flow catalyst downpipes which our customer is really pleased with, and we just got the straight track pipes dialed in on the cnc mandrel bender. Right now we're doing these with 2.5" mandrel bent T304 stainless tubing and waterjet T304 stainless flanges (3/8" thick), cnc turned stainless O2 sensor fittings and bent stainless brackets for a bolt up factory fit. They're a nice design, flow substantially better than the factory hard 90 degree exit design and tight high cell catalyst. Here's our blog post on the catalyst including a photo of the prototype set: http://www.namelessperformance.com/wordpress/?p=54

Stainless Cat-Back Exhaust System

Our customers car is currently equipped with a 2.25" crush bent catback exhaust with the magnaflow x pipe and magnaflow dual mufflers. It sounds pretty darn good but we think we can do better. He's been having some issues with his fuel pressure regulator and as soon as those are resolved and we've got it back out to the dyno for some results, we'll dive into the catback design.

We're also working on an intake system and some intercooling solutions. Improving the heat exchangers in the water air circuit and investigating the performance gains and reasons behind the engine cooling system being connected into the intercooling system are other items we're working on.

And a little bit about us, who we are, why we do what we do, etc:

What's in a name, or lack thereof...why a performance shop would call themselves Nameless Performance

Thanks for your time!

Here's a shot of the pipes fresh off the mandrel bender with a brushed finish. Not sure if that will be an option we offer, not much reason for it all tucked up on either side of the engine block.



Thanks!

Jason

 

I would like to see a set installed. How soon will you have dyno sheets on the down pipes?

 

Can't wait to see the cat-back options.

 

I've got installed photos here on one of our cameras. Just need to get the details into the computer and post them up today. Also have video clips.

Jason

 

So, any progress?

 

Yeah! Glad you asked. We're just finishing up our paperwork to be sponsoring vendors here and we're hoping to post up the press release for our downpipes. We'll be launching a group buy here with a really aggressive discount rate (rolling 2% per person up to 20% off for everybody who signs up) and including the premium brushed finish without additional cost (it'll be a $40 premium option after the fact - because honestly, we really don't want to do it unless it's something people really want...but we may as well put our best foot forward with the community here).

We're also looking into some intercooling solutions as well as a full catback exhaust with some really trick anti-resonance solutions that don't sacrifice flow or scavenging.

What else do you guys want to see for your cars?

Jason, what you're offering is fantastic and I'm sure there'll be a good takeup from the memberbase.
Are you offering for the other models too? X type / S type etc?
I'm looking forward to more of your posts and also the addittion of yourselves as a vendor to the site.
Good luck, and any help you require please let me know and if I can help I will.

All the best

 

aside from costing me money that is, I mean, increased HP, worse emissions, what? I live in CA, so the first thing I have to worry about is whether my car will smog properly after an alteration to the exhaust system. That said, if you can prove they're good and have some real tangible value, I'd be interested. Secondly, are these to be a buyer install type thing, plug and play? Can I jack the car up on one side and install a set? Will these work on many model years?
Just some questions maybe you can start thinking about, thanks, always nice to have some more upgrade options on the table.

 

Have you figured out a way to trick the ecu with the cat delete downpipes? I will probably get a set pending price.

 

We will probably be offering a factory replacement style 400 cell unit as well as the high flow 200 cell and catalyst delete versions. They will all be factory plug and play. The job is pretty difficult without a lift. Fairly straightforward with a lift. If we had to do installs here we'd probably book out 3 hours. We will be offering full installation instructions, potentially with video support where helpful.

We haven't proceeded that far although we do have a complete set of track pipes here in stock right now to begin testing after we get all of the data off of our test car for the catalyst version.

And we do have a lot of ways to run the secondary o2 sensors without throwing a CEL with the track pipe.

Jason

 

Sounds promising. Any ideas yet on cost?

I would also like properly engineered headers. They're probably a pain in the *** to fabricate and probably too expensive, but this is something no one else makes.

 

I'll be posting a press release today with all of the details as they've so far been ironed out. There's only 1-2 variables left at this point. One being the method of attaching the catalyst to the header. Factory is four studs in the downpipe and four holes in the header collector. We have the weld studs for assembling our downpipes this way, but we were also considering making a two piece bolt kit made of the studs and some locating features welded to the top which would allow the installer to drop these in from the top and install all of the rest of the parts from the bottom without requiring another set of hands.

As for developing a tubular header, that is something we have entertained, but it is a tough call from a manufacturability perspective. It could be designed as a 4-2-1 design on each side, eliminating or relocating the catalysts further downstream. Or we could do a shorty 4-1 and shoot for as equal length as possible.

We're also developing a turbocharged exhaust manifold for a BMW inline six right now, and will be posting some blog posts about that and the tools we are using to get that equal length for use with a twin scroll turbine housing.

I'll get that press release up here in a few.

I'd be interested too. Just have to make sure it would work with New York State emissions, which it should because its just a computer check, and not actually hooked up to the exhaust. Basically if it's plug and play like you've said it would be a big plus I'm guessing. I'm looking forward to your performance numbers and price when they become available.
