minimalistic Posted November 13, 2007 Share Posted November 13, 2007 Ok I got my MR CBE installed. I mated it to the stock downpipe while I wait for the Cobb AP. I'll do a full review later. I have a question though. It looks like the mesh section of the midpipe touches the heat shield. I can feel a lot more vibration in the floor board now. Did I install it incorrectly? Did anyone else have this problem? I've included some pics below. http://www.minimalistic.net/personal/mrcbe1.jpg http://www.minimalistic.net/personal/mrcbe2.jpg Link to comment Share on other sites More sharing options...
05Limited Posted November 13, 2007 Share Posted November 13, 2007 I installed it the same way - I'm not sure if it's backwards or not... interested in getting this figured out as well Link to comment Share on other sites More sharing options...
minimalistic Posted November 13, 2007 Author Share Posted November 13, 2007 It doesn't look "backwards" I flipped the pipe over and over while under the car and its identical either way. I was just curious if it was a common Megan fitment issue or if I got a bad exhaust. After a little bit longer drive I do notice additional noise coming from the front of the car which I think is from the pipe rubbing on the heat shield. If I remove the heat shield is it going to melt my carpet or anything weird? Link to comment Share on other sites More sharing options...
RaGe Posted November 13, 2007 Share Posted November 13, 2007 its not that but the drivetrain components will be exposed to that high heat. not a good thing. OTM. Sorry I didn't mean to start a war which mainly forum people is all about . Link to comment Share on other sites More sharing options...

05Limited Posted November 14, 2007 Share Posted November 14, 2007 Yeah, I know it's not backwards - I thought it might need rotating - but if you say that won't help, than yeah, I'd say we have a common issue. Link to comment Share on other sites More sharing options...
minimalistic Posted November 14, 2007 Author Share Posted November 14, 2007 What if I were to remove the heat shield and then use some heat wrap in that area instead? Would that keep the temperature the same in that area? There is definitely a bad vibration noise under WOT. Its louder than the exhaust itself. Thanks for the picture rage but the area that I'm talking about is just out of site in that photo, and it looks like they are using an aftermarket DP too. It could be my stock downpipe causing all the trouble. '05limited are you running a stock DP? EDIT: The more I look at that picture from the Megan CBE thread I notice that it doesnt have the flex section like mine. Its straight until it hits the resonator. Mine is straight, then flex, straight again, then resonator. Maybe its the angle but I dont see that section on the picture above. Link to comment Share on other sites More sharing options...
05Limited Posted November 14, 2007 Share Posted November 14, 2007 The original didn't have a flex section - doesn't sound like my rubbing is as bad as yours - I've got an Autospeed DP - I'll let you know how it goes with an Invidia DP this weekend...I'll do some more serious fiddling then too.

minimalistic Posted November 14, 2007 Author Share Posted November 14, 2007 Thanks, keep me updated. When I have some free time this weekend I'm going to mess with it some more. Anyone else have any ideas? Link to comment Share on other sites More sharing options...
zhabodav Posted November 14, 2007 Share Posted November 14, 2007 I have the MR TBE and both the flex section had to be heated and bent and the downpipe section.... the fitment is not perfect whatsoever, but with minor adjustments its a great sounding setup and its actually very very very sleeper, i have had montreal cops on my ass at a stop light and not pull me over thank god, if I had big cans like perrin or avo I think I would be more likely to get pulled over, it almost looks as if the system belongs on the car.

LGT Dave Posted November 14, 2007 Share Posted November 14, 2007 This is a problem I've seen other people have with the MR CBE and the stock downpipe due to the downpipe's upward angle just before the connection to the catback. There's a few posts about this around here. The flex section was added after the first shipment of them went out exactly because of this problem, but it doesn't seem like it fixed it in all cases. Some people have cut the part of the heatshield that's rubbing out and left the rest attached. I've had my MR exhaust sitting here for over a year without installing it because I didn't want to risk mine doing the same thing. Once the new AP comes out, then I'll be putting on my new DP and the MR exhaust all at once and hopefully (crossing fingers) I won't have any rubbing issues.

05Limited Posted November 14, 2007 Share Posted November 14, 2007 Oh yeah, I LOVE the MR - don't get me wrong, used to have the Autospeed and traded, guess I'm not the man I thought I was... Link to comment Share on other sites More sharing options...
Boostjunkie Posted November 14, 2007 Share Posted November 14, 2007 With some DP's that angle upward a bit more than stock you simply need to bend the heat shield out of the way. The material is soft and you can do it with your fingers or a screwdriver/prybar. You typically only need to move the heatshield less than 1/2", which is very easily achieved.

05Limited Posted November 14, 2007 Share Posted November 14, 2007 Thanks Paul, I'll give it a go when I put my new DP on! Link to comment Share on other sites More sharing options...
Boostjunkie Posted November 14, 2007 Share Posted November 14, 2007 Good luck with the Invidia. It tilts upward more than any other DP on the market. Much more so than stock. I managed to make it work for one of my customers by slotting the opening on the tranny hanger and grinding it a bit to allow the DP to hang lower. I also had to work the heatshield quite a bit.

05Limited Posted November 14, 2007 Share Posted November 14, 2007 Was it a catted or catless Invidia? I read several complaints about the catted being turned upwards, but I saw good feedback for the catless (fitment-wise). Doesn't matter really - it's going on this weekend when it gets here whether it fits or not! Link to comment Share on other sites More sharing options...
Boostjunkie Posted November 14, 2007 Share Posted November 14, 2007 Both the catted and uncatted are pretty much the same. Link to comment Share on other sites More sharing options...

FourMoBro Posted November 15, 2007 Share Posted November 15, 2007 i cut my heatshield in that section. Link to comment Share on other sites More sharing options...
minimalistic Posted November 15, 2007 Author Share Posted November 15, 2007 I dont really want to cut anything up. If I can't bend the heat shield off those sections I think I'm going to take it to a muffler shop and see if they can get it to fit right. Link to comment Share on other sites More sharing options...
RaGe Posted November 15, 2007 Share Posted November 15, 2007 if you live where i am at the only thing you have to do is take them a 12 pack and they will bend or break or cut anything you want. OTM.

minimalistic Posted November 15, 2007 Author Share Posted November 15, 2007 After about 30 minutes of prying I couldnt get it to come off those sections. The pipe is crushed up against the heat shield pretty good. Thats why I feel a lot of vibration and noise from the floorboard. I think I might just cut that section away and wrap it with some exhaust tape. Link to comment Share on other sites More sharing options...
Deer Killer Posted November 15, 2007 Share Posted November 15, 2007 It doesn't look "backwards" I flipped the pipe over and over while under the car and its identical either way. I was just curious if it was a common Megan fitment issue or if I got a bad exhaust. After a little bit longer drive I do notice additional noise coming from the front of the car which I think is from the pipe rubbing on the heat shield. If I remove the heat shield is it going to melt my carpet or anything weird? It is _not_ identical.... fighting with it now.. it's very unclear which way is better.

Deer Killer Posted November 15, 2007 Share Posted November 15, 2007 It doesn't fit. Removing the heatshield won't matter, I adjusted my heatshield until it was touching the driveshaft bearing. Exhaust is touching it. Gah.... Also it's about an inch too short.Mangling the "flex" section will make it shorter. I have no idea how to accomplish that, it's pretty damn unbendable even at exhaust temps. Link to comment Share on other sites More sharing options...
05Limited Posted November 15, 2007 Share Posted November 15, 2007 wait, your pipe is too short? I'm confused... and.... THAT'S what SHE said!!!! sorry:rolleyes: Link to comment Share on other sites More sharing options...
