Cars been at the shop for the last few days. The muffler mod is done and has full 3" perforated pipes through it. I split the packing between the two mufflers and sealed it back up. I also decided not to use the 3" valve on the driver side for now. If it's too loud on start I'll add it in later. It's been a slow process for fitting the full mandrel bent dual 3" exhaust but it's coming together nicely... I have some pics on picasa but haven't figured out how to link to it yet. Google pics for scotte30m3 and you can prolly find them. I hope to have it done today or Monday. I'll try to get some sound bytes ASAP.

To be clear the goal of this is to have a true free flowing dual 3" exhaust from the Turbos back withou being much louder than stock. I'm having RBs installed mid late next week to use all that free flowing exhaust...

Ok so if you do a google search for scotte30m3 all you'll find is my IS300 2jzgte BUILD. So if anyone can tell me how to link pics from Google+ I will post pics...

Anyone do this to an e90 without the xpipe?

Initial reaction no JB4 installed... Lots of Rasp and drone from 2000-3500 RPMs. Anything over 3500 RPMs was OEM. I was shocked!

(Side note, my Secondary cats must have been completely stopped up cause I could not boost over 12 PSI with the JB4 installed After ALOT of troubleshooting I found at least one turbo was leaking oil out the front and had about 2-3mm of shaft play up and down. So I took the JB4 off and scheduled time with the deal to have RBs installed, woot. With no JB4 installed the car was very anemic to 8psi and would fall flat on its face around 5800 rpms. I attributed this to the turbo failure. Now that the exhaust system has no the Secondary cats and no restriction at all it pulls like a freight train to 7 grand... Unfortunately the turbo is still leaking oil and still has shaft play and the RBs were already on order so I'm still doing the RBs)

Back to the review,
Last night I started looking at ways to change it to be more OEM lower in the RPMS... First thing I thought was, I need to put the driver side valve back in it and assure that it is working. I found a valve online that would work and got it ordered. Should be here tomorrow or Monday.

I woke up this morning still disappointed and started the car... and the disappointment got worse. Got home around lunch time still disappointed and but decided to re-install the JB4 so I could read the engine codes and see if I could run more than 12 PSI. I Let the car cool completely down, installed the JB4, then started it back up and to my surprise the car sounded different. I have know idea why. The drone was not nearly as bad and most of the ting went away... I took it for a drive again drone was almost gone as well as the fart sound. Started with Map 0 to assure I had the same results with no JB4 and all is well, switched to Map 1 and hit my target PSI, moved to MAP 2 and hit my target PSI. The car is definitely faster than the day I bought it a year ago... The thing that has be confused is why would it sound different from just installing the JB4?

I still plan on putting the OEM style valve in place. This should eliminate drone and rasp all together.

So now I need to post pics and videos... before and after RBs.

Should be in the air tomorrow or Monday... I'll get better pics of the V-BAND connection at the DPs

I don't get it... This whole mod is about replacing the perforated pipes in the two exhausts with solid pipes. What have you done exactly?

Looks like you just put in a shorter section of perforated pipe?

Yep
We've put a lot of work into trying to make the information easy to follow for those who are reading this thread. Now many are going to think the mod is raspy when it's not the case at all. This is a completely new 3" custom exhaust that just uses the oem muffler.

While cool, it's probably deserves it's own thread. It will probably recieve a lot more attention there as well.

Anyone in the Orlando area that can do this mod?

This whole thread is about modifying the stock muffler... I modified the stock muffler with 3" pipes while retaining the OEM design... My exhaust setup is dual 3" pipes turbo back and through the OEM muffler.

Anyone in the ny area that can do this mod I have a xpipe and some nice black tips ready to be installed along with the muffler mod

Where in ny? I have a guy that's done it before and is doing it for me next week in albany

[oogabooga]

I think everyone is starting to wonder where they can get this done. Big thank you to everyone involved on getting this information together and figuring out the recipe.

Anyone in Northern California have this done by an excellent muffler shop? Looking for a place and definitely want to go somewhere that has done this before and will do top notch work on the welds. Thanks.

Just got it done to my n55. Just pe mod. Since I'm n55 e90 I already have factory xpipe. I'll get a better clip later. Here's a cold start clip

Edit: here's a link to it since I'm using the app

sounds good!

thats interesting, i thought even the n55 e90's came with the res instead of an xpipe. also, what exhaust tips are those?

[nyfg56]

Thanks man. They are stock tips. I bought some 4 inch tips but my guy didn't have time to do them today. I'll post pics next week when I get them

[Conti.]

guess its the angle, they looked bigger to me. what tips did you end up getting anyways? and be sure to post some driving vids to!
