Some of you guys may know of me. I'm a mechanical engineer and started SMS Products about 5-6 years ago. I've been building race headers and exhaust systems for Hondas and Acuras plus some other cars for this period. Many people and race teams use my products with good success.

I'm currently working on some initial designs of the K20 and K24 headers for use in the TSX, Integras and Civics. If any of you are interested and live in the DC area (I'm right off Exit 126 of I95) please contact me.

Also, please realize that the majority of my stuff is no bolt on. I go into why at http://sms-products.com/Intro.html, you can also read about how we build headers here http://sms-products.com/Construction.html

Thanks for you time.

 

Thanks David for getting this started for us. I look forward to seeing what you can build for us. Here's our chance guys...

I will be at college for the next couple months and I live in PA. If I can be guarenteed that my car will always be inside at night and whenever now one is around we may be able to work out me to drop my car off for a couple months for you to use.

 

WOW
That's some commitment there.

James

 

I would assume the test vehicle would receive the header for free also.

 

xizor is also in the VA area and needs a header

so is CGTSX2004.

 

This is probably the only time I wish I live in the northern east coast.

 

Too bad I'm no longer on the east coast. I'd be all over this.

James

 

Damn, Fredericksburg is a stretch from my place... 12hr drive... I'd be all over it too! (Assuming the parts developped would be a freebie)

 

Yea, i'm in NY, but i would if i was closer

 

haha! I'm 10 mins away

You have PM and email

 

Ha, not really northern east coast.

Up here, we consider Virginia pretty far south.

 

^^^ You just proved that my geography sucks then.

 

Ahh, sorry it wouldn't be free but there would be a discount. Also there may be multiple headers built to find the best design. For example I built and tested 5 headers for the H22 prior to starting production.

 

Providing test vehicle with no free product?!??

 

I'd be interested to see if you could build an exhaust system with optimal performance with the only restriction that it would be able to retain both o2 sensors and not trigger a CEL.

 

Well I'm sorry if you feel that way but I'm a very small company. I don't have the capital like CompTech, Magnaflow or Toda. But I hope to produce something that would net better gains also.

Here's a custom header I built for a guy in Canada with a 5th gen Prelude H22VTEC. Those engines are rated at 195bhp from the factory and he has stated that on the dyno used for the test below a stock H22 puts down around 140-145whp. This engine has a stock bottom end, Jun cams, TWM ITBs and runs the AEM stand alone system.

This comparison is between my H22 header and a Mugen header.

My header.



Mine vs Mugen



His estimate when he extrapolated the Mugen graph



and this is what he wrote about it,

"At 8000 there's a difference of 16whp(205 vs 189). The gains would be 25whp if I revved to 8300 with Mugen setup. Now if I extend the Mugen curve out to 8700, the difference would be a whopping 35whp (200 vs 165)!! "

 

Well the collector will most likely be 2-1/2" so I will also be building a cat and cat back system for the car. So the comparison will most likely be a full stock system versus a full custom obdii system.

However, the donor car will go home with the stock system on the car since I WILL NOT install my systems on street cars. If a street car comes into my shop with a header and no cat, then by law I have to install a cat prior to doing the exhaust.

 

That would not be a problem to me. I'd just need to find a place to install it before I cross the border. Needless to say, I'd drive down to get it.

But let's see what you do first. Dyno sheets would be appreciated.

 

My car would be perfect for this, I'm in NOVA, have a bone stock 6MT 05 TSX. However, with no free header I feel this is not worth it. I'm confident SMSP will put out a strong producing header and perhaps when that happens I will buy one. If there was a free header in this I'd be all over it.

 

just like your driving skills

 

Geez. Everyones looking to get something for free now-a-days. Give the guy a break. First of all he has not stated what will be involved with being a test car. Maybe he only needs the car 1 day a week or something. Second of all he's stated that he'd offer a discount to the donor car. What more could you ask for. Not many people I know are going to give away a $1300 header.

James

 

yeah, like he said... hes a small company... he doesnt have the same capital for R&D as the big guys

 

Fabricating is not easy and takes time. It's not uncommon to fab up many versions and only one would make it to production. We are not talking about simply piecing some tubes together guys. I think a discount is very reasonable.

Btw, if the Toda header is being made in Japan, which engine are they using to create the header? Is it going to be optimized for our engine?

 

Good point. I had not thought of that.

 

If they use the 2.4 Type S or Euro 2.4 Executive 190hp should be good. My understanding is that the 10hp difference is in engine management.

 

SMSP you have been pmed.

 

lol I've been talkin to him for days

Update for everyone else: Looks like I will be the test car. I'll be dropping my car off for a couple weekends and I'll be sure to have a dyno pulled after everythings all set. All I have now is a Comptech Icebox for the before dyno will look exactly like that.

I'll keep you guys posted!

 

This is good news!

 

Cool! Is it going to be just the header or header, cat and catback?

 

I've looked into this before with my Integra, but is there any way this will be CARB legal or exempt? (I pretty much know the answer, but its worth a shot.)

Great product for sure though. Will the muffler be a twin pass system or a straight through muffler? I might be interested in the catback portion if anything.

 

we are just talking about that now. I'll let you know when I hear back from him.

 

You need to get the complete exhaust done! I'll be watching the numbers closely.

 

Damn you! j/k. I hope it all works out for you. I'm excited to see the final product.

 

I'm always a little hesitant to get the whole exhaust done because of the sound... I hate sounding all loud and obnoxious and (dare I say it) ricer...

 

Get him to design the cat back with a baffle. It's a joke to design it's so simple. I designed one myself once for my on Tanabe (improved the one they actually supplied) and I'm nowhere near an engineer.

 

how much louder is it then stock?

 

With a baffle it's usually very reasonnable. But it is always still related to the design of the exhaust. A full-race catback exhaust without a baffle must be LOUD. It would be significantly better with a baffle, but still not as quiet as stock or maybe a Comptech exhaust.

But performance would be at the rendez-vous though. Depends what you're looking for.

 

yeah... that's what I have to decide.

Well, I'll talk to him and keep you guys posted!

 

I never got a PM back from SMSP
