My car runs with 3" DP, single 200cell cat, 11 inch resonator with this Magnaflow muffler (link below).

Sounds freakin awesome.

But since seem to want to keep fighting me about it here it is. You will see the inner lip I am talking about, if you take the internal diameter of that it will be 2.25. Now without that inner lip it would be closer to 2.5.

Gotcha. Thanks for the clarification. I'll see if I can respond to Magnaflow with this. See what they say.

On more video of my UR DP + CS RP + CS CBE. Just a few revs and a launch fail. Wanted to get a quick video before putting in the resonated TP this weekend.

Damn that sounds sexy. Curious how it sounds with the resonated TP but it sounds pretty damn good as is. I think this is one of my favorite setups that I've heard so far.

No doubt. I absolutely LOVE the way it sounds. But it's just a tad bit too loud and has too much drone at part throttle for my liking. I'll try to get another video once the resonated TP is in.

Hell ya do that! I'm most likely getting the CS exhaust system, but am still unsure if I'm doing a full downpipe or just getting a race pipe put in. But wanna see how this setup fully sounds.

I really want to hear one with a catless dp and rp but with stock cbe!!!!

I read that yours was completely custom and if I read it right all you had done was a resonator delete/muffler delete and just straight pipe from the Cat up to just Tips at the rear bumper or did you replace the 2nd Cat with a Test Pipe? If you replaced with Test Pipe what did you have the shop do? Cut it out and weld in solid pipe or install one from like CS or Cobb/Cp-E? I really appreciate the help. I only have a CS SRI/TIP and am looking to get my exhaust re-done. I'm avoiding the lucrative Fuel Pump replacement until I get my suspension/wheel setup done. Thanks again I hate not having a high post count....

Yea I went to a local shop had them cut out the muffler/res and put straight pipes. If youve ever seen under a srt-4 the stock exhaust it looks like that.. I went to another shop and had them cut out my 2nd cat and replace it with a 2.5inch pipe. So 2.5inch all the way back the tips are like 3-3.25 inch.

^^+1!! I'm curious how it sounds, or even with the stock exhaust with the res delete mod. I'm trying to avoid buying an exhaust system for my 3.

edit: i just found this real quick on youtube. granted, it's for a Gen 1 but I guess could give some insight on how it sounds.

Need to find a clip of OBX cbe for 2nd gen

OBX Mazdaspeed3 10 + Catback Exhaust System 2010 NEW | eBay

[dizzydtrain]

How is the OBX exhaust so inexpensive?

[skeurton]

Installed the UR Resonated Test Pipe today. I gotta say that it was exactly what I was looking for. Still has the same exact tone as with the straight test pipe, but not nearly as loud and without the annoying drone. I can use the handsfree bluetooth now and actually hear the person on the other end of the line!

So now I'm running a UR catted downpipe + UR resonated test pipe + CS catback. Post #368 above has a video with the CS straight test pipe.

(Sorry about the cell phone video. My regular camera's battery was dead.)

Forgot to mention that there are no adverse effects in terms of performance with the resonated test pipe. Did a datalog and hit all my targets just the same as with the straight pipe. So UR's claim on their website of "100% straight through flow" is 100% right.

Ok so on with this exhaust.

Ok so i guess i will be the first to confirm a purchase.

Just ordered it should be here in a week since im in MD and its coming out of cali.

I have my vacation that following week and it will be installed then unless it arrives this friday I will install it this coming weekend

My guess untill we get true facts that this could be the ultimateracing since they offer the tip differences.

Not calling anyone out but hopefully being a stainless system and hearing nothing but decent things about them this will be a good buy.

[adrager622]

If I went this route, wouldn't be doing it until the spring. At least this video gives some insight on it.

Wow, very impressive. Sounds no different than a TP. I bet it sounds badass in person. Thanks for posting this!

Since I have a cobb dp I obviously can't get the resonated tp but I am wondering if there are any other solutions for someone wanting to go cbe? The stock resonator as far as I can remember is right behind the tp. Is there anyone selling an aftermarket resonator that could be welded into a cat back like the OBX or UR?

Not sure if this is even a solution but I am trying to stay away from drone with this car since I had enough of that shit with my last dd. I really don't mind the stock exhaust but would love a deeper exhaust note.

Good stuff, keep us posted

[TurboJew]

Heres my original thread not to jack but if anyones interested in reading whats going on.

Another member bought it aswell we will try to update and get pics and vids up asap.

exhaust

[f-castrillo]

Man, I really like how the CS exhaust sounds, but because the CNT Racing DP has a welded TP section, I don't know how I'm gonna stick a resonator on it so that the sound isn't nearly so deafening.

[Todd98SE]

Because it is a knockoff made from inferior material and shoddy fabrication. Looks like they bought a genuine UR catback and shipped it to China for "reverse engineering".

IF YOU BUY THIS CRAP YOU CONTRIBUTE TO THE DEATH OF THE MS3 AFTERMARKET!!!

Revenge of the Nerd- Boycott Fakes!

[Todd98SE]

7MAR and anyone else that groans this post, what part of NO MORE AFTERMARKET SUPPORT do you not understand? This is the exact type of thing that drives our supporters out of business. Don't be a cheap ass ricer, buy legit parts.

[adlpb]

I think everyone's entitled to purchase what they want. If they wanna be cheap and buy crappy parts, then they'll learn their own lesson. However, if this company proves to be of somewhat good quality, then they have all the right to grow as any other. All the current companies we purchase from started out small at some point.

[Todd98SE]

Have you bothered to even Google OBX? I don't have a problem with cheap crappy parts, people that buy them will learn their lesson eventually. I do have a problem with companies that buy an existing product, build a jig for it, copy it, and sell it for dirt cheap, undercutting and driving the originator out of business.

[adlpb]

Listen buddy, you need to calm down. I'm talking about any company in general, not OBX. If their parts are shit, then the customers will find out for themselves. I am just explaining that you probably shouldn't be saying "you should not be buying x product because it is ricer." If they want to buy this copy piece of shit and be cheap, then so be it. They'll find out for themselves and will regret it if it breaks on them.

[Todd98SE]

I agree with you wholeheartedly adlpb about buying cheap parts and if they weren't copies I would tell the guy to go for it but I can't stress enough how bad it is to buy knockoffs in this industry. Most of the small time manufacturers cannot endure the economic hardship that copy cat part manufactures place them in and then they go out of business. I witnessed this first hand with Hotshot Performance and OBX had a big hand in their demise.

I offer this scenario: Who would be pissed if I managed to port the Cobb Accessport software over to a generic flashing device, sold it for $200 and drove Cobb out of business because they now cannot recoup their R&D costs on Accessports. So now we lose any firmware updates, 2010/2011 MS3 support, new maps, etc. that Cobb may have eventually come out with. This is what I mean by killing future MS3 development by buying knockoff parts.

Quit your bitching, your rambling will now skew anyones opinion on what they want to buy. Do you know how many parts are "knock offs" lol. CNT DP for example, but that shit is legit.

[Todd98SE]

You guys are missing the whole point. Fuck OBX.

[Broxer]

In 4 sound clips and reviews. Normally wouldn't buy a knock off but its not like companies spend much on R&D for a CBE. Besides, $800 seems a bit over priced.

@CCC has the best sounding exhaust ive ever heard on a mazdaspeed

Thanks, I am really happy with the way my setup ended up sounding. I was checking my boost and it seemed to be fine with the catless setup too.

I went out for a drive tonight, and the HIDs really are great too, thanks again for your help today with all that stuff.

I assume this is the one you got? Did the presilencer not fit with the CNT catted DP? How's the sound volume increase over just the CNT DP by itself? Looks like I have a winner here...

[BlueDmnSpeed]

@f-castrillo

No it's not that it didn't fit I just asked them to fab a staright pipe instead of the presilencer. Bmylez suggests that if you are going catless then get the presilencer. I say if your not go without the presilencer. As for the sound. I installed the exhaust first then wen and had a shop install my DP. Before the DP it was too quiet but nice and deep. After the DP it go louder but not too loud. Definitely no where near as loud as the UR or CS CBE's.

[Ex_WRX_driver]

UR CBE is loud as fuck. I like. Neighbors probably hate my morning warmup. lol
