Marcy Motorsport 2.75-inch "super-quiet" exhaust - Feeler Thread - Focaljet

**pitchblack23** · 04-19-2006, 03:28 PM

Hello, Forced Induction forum! I come in peace from Duratec Tuning!

I don't know if you're familiar with Marcy Motorsport or not, but to Duratec owners they're one of the most loved-and-hated [FJ] sponsors around. Or rather, he is, since Marcy Motorsport is 90% Walter Marcy himself. MM is the group which put down some 220 naturally-aspirated horsepower and matching torque numbers several months back. Lately we've caught wind of yet another project under consideration: a sleeper-style exhaust for high-output Foci of the NA, turbo, supercharged, or even nitrous-fed variety.

The only problem is that MM is a bit... "grassroots", so to speak. One man in a shop can't be expected to produce all of the ideas he has unless there's a market for them. That's why I've come to tell you a little bit about the exhaust in hopes of drumming up interest.

The Important Parts
This exhaust will be:

2.75" inches in diameter, intended for any Focus making over 160 whp, regradless of the engine used.
Quiet! Quiet enough to avoid suspicion even on a catless 2.3, which is earsplitting with any other off-the-shelf exhaust.
Made of non-stainless steel. This is to keep costs down, and because Walter feels it has better acoustic properties than stainless for this application.
Stealthy. In addition to its quiet nature, it will end in a 2.75" slash-cut tip similar in appearance to the stock SVT tip.
Slip-fit like the Borla exhaust, with similar band-type clamps. It will have a flange to bolt on at (correct me if I'm wrong) a Zetec's cat pipe, or a Duratec's flex-pipe. This makes it emissions-legal on a Zetec.
Intended for hatchbacks, because they're coolest

Walter Marcy has already said that unless there are 15-20 interested Focus owners, this exhaust will not happen. So for those of you who have not yet stepped up to a custom 3", please stop and consider throwing your name in on this. You can find a "sister thread" over in Duratec Tuning. If you're very interested, post your name there.

This thread is now about discussion, questions, and (if I can find it) a video of a catless Duratec 2.3 revving with this exhaust.

(PS, this crosspost was officially okayed by FJ-1.)

Sounds like a great and well needed product for the supercharged guys. And a nice additional option for the turbo guys.

If I had a supercharger, I'd want to open the exhaust up as much as I could. ie. race header and big flex pipe. But we all know the ear bleeding sound produced with a race header... So many are left with the stock header/cat in place if they want to remain somewhat quiet. Either that or they have to modify their exhaust a few times to get it quieted down enough. So the option of a ready made 2.75" exhaust sounds like a great alternative.

Only suggestion I have would be to make it optional to add/subtract the addition of the extra resonator(s) required to keep things down. If possible within cost targets. The reason I say that is, with a turbo acting as a muffler, I do not need any more muffling than my 2.5" Borla gives. My point being...Turbo cars, by nature, already have a nice built in "muffler" that quiets things down quite nicely.

So it might be an interesting idea to market two systems. One for NA and supercharged cars that has perhaps an extra resonator (or whatever Walter is using to quiet things down) and another for turbo cars sans that extra resonator. That is, of course, if it does not raise the overall cost that much.

In addition, the choice of 2.75" seems pretty nice. That should stop the questions of "Should I get a 2.5" or a 3"?" Why not get something right in between. Sounds like Walter might have the answer.

just my $.02

**FuryFocus** · 04-19-2006, 04:00 PM

sounds cool to me, would save me from having to get a custom 3inch. but id have to hear it on someone elses first

in estimate in price?

**jonfrow** · 04-19-2006, 04:05 PM

I would want want if I could fit it onto my SVT

**pitchblack23** · 04-19-2006, 04:06 PM

Approximately $350 for the exhaust as it's planned.

I found the short video I was looking for. It has a Duratec 2.3 with race header revving a bit. Unfortunately, I don't have any hosting, so I'm waiting for the guy hosting it to tell me it's okay to repost it here.

Edit: The video is of Aerostudent's car, actually.

**aerostudent** · 04-19-2006, 04:06 PM

price estimate is $350 and yes it would fit an svt.

**Penguini66** · 04-19-2006, 04:31 PM

In short term, you could always upload it to www.rapidshare.de

**pitchblack23** · 04-19-2006, 04:47 PM

Uploaded. You can download it here:
http://rapidshare.de/files/18438281/MM_exhaust.AVI.html

This is Aerostudent's car, I think. It has no catalytic converters or muffling other than the Marcy Motorsport exhaust.

**BUR_ZX3** · 04-19-2006, 05:07 PM

The price is certainly right... I'd be interested in stepping up from my 2 1/4"...

**CrazyWella** · 04-19-2006, 08:13 PM

Id be down for it if it were something that wasnt going to rust, My only fear is it NOT being stainless. I live in Michigan where it snows 3.5 months of the year and they like their road salt. Anything BUT stainless will be eaten up in only a couple of years.

**jr_psychologist** · 04-19-2006, 10:21 PM

I'm curious about the choice of 2.75" for the diameter. It seems like it's more than N/A needs, but less than the 3" most FI guys seem to be looking for. Is it that 3" isn't going to do much more for F/I either until beyond what most are going to see (i.e., until 300+ whp)?

**COSDEVSVT** · 04-19-2006, 10:47 PM

I might consider it ... a bit worried about it being non-stainless for the same reasons as CrazyWella

Great...we agree, now give me a supercharger! LOL.
In reality, I hate my loud exaust. I wish there was something more I could do to make it quiet.

**BUR_ZX3** · 04-19-2006, 11:00 PM

Unfortunately, I think that this is very much a cheap alternative for us lucky folks in the sun belt. To make a stainless system is just far too expensive anymore.....

This is meant to be a cheap offering, I'm pretty sure. Not the indestructable will stand up to anything piece that those in the north will be needing, unfortunately.

Marcy believes that a naturally aspirated Duratec 2.3 can easily utilize a 2.75" with bolt-ons and cams. His old engine actually showed torque gains from idle on up when he put a 3" on it.

**TM3** · 04-20-2006, 08:36 AM

Shoot, I'd be down for shizzle. Go ahead and add my name to the list.

**dimm** · 04-20-2006, 08:49 AM

If I can find the bmw guys exhaust thread I'll post it, don't meen to take it off topic the torque gain post made me think of it.
He did two different styles of exhausts for testing purposes. One was super smooth full mandrel bent system and the other was using autopart store bought crimped bent exhaust tubing.

You'd be amazed by how much the crimped bent exhaust outperformed the full mandrel bent system. It outperformed the mandrel by almost 4 hp and about a 1ft pound of torque.

**c4uldr0n** · 04-20-2006, 09:13 AM

dimm, because you can gain tq from more backpressure, so a 3" crimp is actually ~ 2.5" at the bend. doing crimp defeats the purpose of upgrading your exhaust to larger sizes. if you're doing exhaust to get more breathing that crimp isn't the way to go.

MMS has a great product, and a great price, got my vote (just can't afford it currently)

**PastyPyro** · 04-20-2006, 01:17 PM

Something like this fills a huge gap in the focus market. This and the new XIOS turbo setup would make a very quiet and possibly even legal turbo focus.

**GringoZX3** · 04-21-2006, 01:24 AM

Come on guys, I have 9 people on the list already....6 or 7 more people, and we're golden.

**d.bluefocus21** · 04-21-2006, 11:12 AM

id' be pretty interested.....would this make more of a gain on NA zetec in comparison to a 2.5" Borla?

and is there going to be one for a sedan?

you don't gain torque by backpressure

I still run a stock exhaust with my vortech because I hate loud exhausts (that and the second hand focussport (I think) setup I bought needs recoating and more resonators.

It depends on what's been done to the engine. On a mildly-modified engine, you'll probably lose a lot of your low end.

There hasn't been anything said about a sedan version. I'll ask Marcy. It seems like it would be fairly simple to make both systems.

Edit: It's true that you don't gain torque by backpressure. But you do gain torque by velocity, and velocity often goes hand-in-hand with backpressure. The trick is finding an exhaust where velocity is highest and backpressure is lowest at the same time.

**CrazyWella** · 04-21-2006, 09:06 PM

Would Walter be willing to cinsider making a few out of ss for us poor bastards that dont live in Cali?(obviously at extra cost to us poor bastards) lol

**griffin12803** · 04-21-2006, 11:25 PM

I heard through the rumor mill that COSDEVSVT is already working on a system but I believe his is going to be stainless... can anybody confirm this??? If whoever he has doing his harness bar stuff is doing the exhaust stuff also... it'll be a work of art.
