Exhaust - let's talk about this one!

[Silver Ecstasy]

Yeah the MPS exhaust is definitely different!!

I've been following the Grassroots Motorsports Magazine articles for their MS3 project car. They will be posting an exhaust modification in an upcoming issue. I've been leaning towards the MSCBE but everyone at my local dealer tells me that is a just a slight upgrade in sound compared to the stock exhaust. I've checked out the Cobb website and love their complete exhaust system, but its alot of money!

Wow, that's a huge muffler. Where are the resos? Maybe between that muffler and the exhaust tip? Our muffler (or what passes for one) is the very end of the system, right ahead of the rear bumper. This is much different than the US spec CBE.

We also have a little muffler near the exhaust tip, like MS3.

I've installed Corksport CBE, and I really can fell the difference in power!! So there's a restriction on CBE on 3 MPS!!
And I really like the sound, it's quite louder when engine is cold but it's ok after.
I've also have a SU test pipe and fit like glove with the CBE

I'm wondering if noise level will be louder if I add Corksport Downpipe with Corksport Test pipe with High flow Cat (I don't wanna run catless)??

What size diameter is your MPS exhaust Zaka?

Well while we're talking exhaust I ordered the dp picture below and installed it last summer, for the rest of my exhaust I used my buddies shop to weld 3" steel exhaust piping together to make the exhaust welding on exhaust clingers in the same placement as the stock exhaust. I cut off the stock tip and welded it to the 3" pipe so as it sits right now my exhaust from a passerby looks no different than stock. So my exhaust is pretty much a 4" to 3" dp and then 3" straight pipe all the way out. I haven't had any problems with white smoke like i've read a lot about, she'll just put out a healthy bit more black soot when I really romp on her. Right after I put on the dp it did smoke a little and had a weird smell, but I just figured it was break in on the dp, and after a day or two of driving it went away. Yeah it's pretty loud, but not ear splitting loud, inside on the freeway it is pretty loud but still not enough to annoy me. But outside is a different story especially if you standing behind it. Sounds like a diesel, Ken Blocks STI, and Evo had a threesome and this was the offspring. You can really hear the turbo whine and the growl that come from a turboed motor. I have had nothing but compliments on how it sounds, it wasn't no where near as loud as I thought it would be, I've pretty pretty happy with it, got about 10k miles with this setup and no problems so far. I didn't think to take any pics of the fabrication, I'll put some up next time I'm under there. I did however make it so that if I put my stock dp on and can also put the stock secondary cat on too if I needed to, just no resonators or muffler....

So it's just completely straight piped? Have any sound clips?

 

[blh_wakeboard]

Yup, all straight pipe from the turbo back... I do, but unfortunately not this computer I am currently on. I have a couple of vids on facebook...

I'll bet that car smokes like a chimney...(no offense, just logically what is supposed to happen).

Exhaust Video

Here is a video of my car doing a flyby. Tried filming it on my cell phone, quality was bad so I broke out the d90, so there you go...

Actually no it don't, I know it should, but it doesn't. Gave her the seafoam treatment tonight, did it through the vac line that has the blue clip, smoked a bit but not tons. It's a 2008, not a 2008.5, guess I got lucky and got a heathly turbo, I never take it past 500 rpms below redline. I know in the video above at one point it sounds like I do but I was holding it at 5500 because I had some major wheel spin in 2nd...

i run only 93 shell gas and syntec oil mainly highway miles and if my turbo smokes i would never know. it doesnt have time to accumulate and smoke ever. i ran seafoam and nothing came out at all. it all depends on how you drive it and like said whether you got lucky or not. sounds good! s**** loud! lol.

ok, to OP, after reading 9 pages of posts it can definitely be said that if you want a CBE then it is purely for the sound, and that the DP/RP combo is for all of the power junkies. So in the long run, to answer your question, no, it isn't worth it to buy a CBE. But, OP, you did buy one so the thread kinda lost its original point.

But, to that point; power gains or sound, whatever your reasons for buying an exhaust are at least know why you're getting it. Don't buy it for sound and expect to get huge power gains, don't buy it for power and complain that its too loud. The fact of the matter is that part of the enjoyment of driving a high-performance car is the sounds that it makes. Ask any BMW owner, especially an M owner, if they enjoy the way that their car sounds when driving hard. Furthermore, why would it even be mentioned in car reviews in Car&Driver and other auto mags like that?

If you wanted a quiet car, go drive a Prius. But the fact that some of you actually complain about the "drone" at idle on the stock exhaust is laughable. Try sitting in a race-prepped RX-7 for about 5 min, THATS drone at idle. Its like people actually expect their cars to be whisper quiet. Either way, the speed 3 is quiet at idle, quiet at cruising, and only the engine is loud at WOT. Seriously, outside my car, the injectors are louder than the stock exhaust at idle. I will say that the loudest the stock exhaust gets is coasting (power-off).

I for one, am actually looking for both sound and power with my exhaust set up. But I'm not afraid to let people hear me coming. And no, loud is not always for 17 year-olds. Thanks for your opinion, but there is a difference between a loud tuned exhaust note, and a loud "fart-can-welded-hack-job-Pepboys-APC-POS" exhaust note. I ran an Apex'i N1 exhaust on my '91 240 for years. At WOT you could hear me for blocks, and it sounded incredible!!

My 2000ES is non turbo the question is if i'm running with stock pipe and headers but i have a 4.25'' muffler will it affect my motor compression? how doest it affect my motor?


thanks

So i'm okay with admitting I bought the exhaust mainly for sound, but now i'm sort've wishing I hadn't. Not only does it do nothing, but it definitely changed the power delivery where the torque down low is reduced. I only regained a little back when I switched from the MSCAI to the Cobb SRI+TIP plus Forge BPV.

The stock exhaust definitely had more drone than my MSCBE though, surprisingly.

 

[joelgas]

^^ Silver...I felt the low end torque reduced too when I put the MSCBE on. Higher RPM range is fine...maybe a little better. Have you tried a testpipe or a tune yet?

 

[Silver Ecstasy]

Nope, haven't had the time to test anything like that. Good suggestion though!

I will let you know how it works for me. Will be installing a CS Testpipe and a PG Inlet. Also gonna run an AP tune with the MSCAI.

 

[Silver Ecstasy]

SO... I'm thinking I am just going to give this a try and re-install my stock exhaust. It's cut, so it would involve some welding, which hopefully shouldn't be too much of a problem.

In the meantime, who's looking for a MSCBE?..
