3. Removed 95% of packing left only a handful in each muffler. Just enough to coat the bottom of the muffler

4. Didn't touch any piping

5. Zero drone (6at so I'm very happy)

6. Brought some more growl in the bottom end but really haven't got enough seat time to give an honest review.

7. Tomorrow/Saturday expect a new thread that will include videos and pictures

8. I am very happy with it so far no regrets

Want to hear video!!!

Can't wait! Hopefully you won't disappear like the last guy that said he was going to post videos and a thread for everything.

Im assuming thats me you talking about lol

I been busy but im here at the muffler shop right now getting the moddified mufflers installed.

*They replaced all perforated pipes with ss pipes.
*replaced the mini muffler inside with ss pipe.
*left all packing inside the mufflers intact and everything else as it was for that matter.

Videos will be up next.

Hey ya'll sorry about the delay but i been busy with work. Im now dealing with what i think is a boost leak after installing a CPE charge pipe AFTER installing the modded exhaust so i havent wanted to take out a video until all is running great again.

for those that want to expedite the exhaust videos and want to help i get the half engine light momentarily when going full throttle however power does not seem to be affected. i cant locate a leak in the throttle body? Maybe boost sensor got fucked up in the install...

So to recap the exhaust shop.

*Replaced all perforated pipes with stainless steel one (4 total)
*Took out the mini muffler/resonator inside the mufflers
*Put all packing material back inside
*left everything else as it was.

My initial reaction was.... Wow this is not loud AT ALL and i was a bit disapointed at that, however im coming from Magnaflow mufflers (very deep and loud sound!) so i think my ears are now fucked up from the Magnas

The exhaust gurgles back again now (didnt after Magnaflow muffler install) and its got an aggressive tone however imo it needs to be louder. I like the fact that there is 100% no drone now, which i did have with the Magnaflows. For those on the App that cant see my mods im basically FBO on JB4 map5 running 50/50 e85/93.

Yesterday night on my drive back home right before the CPE CP failed install i did get to take the car for a drive and thats when i started to really appreciate the sound, basically the sound i had when i had my OEM mufflers untoched with DPs and fully FBO but better, more aggressive and gurgley.

So i really like the exhaust mod sound but i want it louder! Im thinking on replacing the resonator on my e90 with a X-pipe to see if i can bring out the sound even more.

For those of you thinking that replacing the perforated pipes with solid pipe is basically a muffler delete, well its not, nothing like a muffler delete. Not nearly as loud and NO DRONE.

I will try to get my charge pipe/ boost issues resolved this weekend so i can post some videos and i will post some pics of the modded cans as well.

Is anyone with a BMW PE willing to meet in the South Florida area so that i can compare the sound? also anyone thats FBO, golf tee mod and untoched OEM cans so that we can compare and take vids.

late.

StevenY. · 12-21-2012, 09:51 AM

^ Sorry about your issue! Hope you get that fixed. From your description the modded muffler seems to have a good sound, do you think it would be loud if you removed some packing? I'd imagine it would make it a bit louder. Also, good idea on trying to get comparisons it would really be nice if you can get that together. Anyway, good luck on fixing your problem!

I dont know but i suppose that it would be louder without the packing however the muffler tech recommended i keep the packing for rattling, heat, drone issues and so far i have none of those.

I think that replacing my resonator with an X-pipe will finally bring the sound im looking for.

Thanks

Airdanny · 12-21-2012, 08:22 PM

^ Sorry to hear about your problem, hope you get it fixed soon! On the other hand, aside from the muffler mod, what else have you done to your exhaust(catless dp, 2nd cat delete)? Currently I have 3" catless downpipes, X pipe insetad of resonator, secondary cats and OEM muffler... I know it might be difficult for you to compare, but how does my exhaust sound compare to yours? I deffinately want mine louder, so am debating whether to remove secondary cats and remove the mini resonator inside the muffler...
Thanks!!

^^This. I did take out the packing though. And changed the lag fix on my JB4 to 80, which makes it sound SWEET! I get compliments all day when I go to meets!

Heard it yesterday, it just gurgles everywhere. Sounds awesome

Also, don't know if you guys have seen/heard this one before:

335ixdrive2009 · 12-22-2012, 04:58 AM

I Just purchased the BMW Performance exhaust yesterday and installed it today! It is INCREDIBLE! Really happy with it! catless downpipes are my next venture but i need to get on my Techs goodside so i dont have to take them out everytime because it is a $300 uninstall+ putting them back in afterward. Any advice?

Thanks for doing the vid, though I would have also loved to get sound clips from INSIDE the car, since that's where I am normally when I hear the exhaust sounds, and not sitting on the trunk lid!
