340i - JB4+Decat vs MPPSK
Hi all,
Been doing a bit of a search and can't find the specific question I am interested in. Basically....I'm looking at adding either (not both) JB4 + Decat or MPPSK The JB4 route offers more power, for less money The MPPSK route offers warranty, for more money In terms of sound alone... has anyone done a comparison vs Stock Exhaust + Decat vs MPPSK? Thanks! |

Are you planning to lease or purchase? MPPSK or Dinan bits will add value when traded in or sold outright, JB4, Active Autowerke ect will most likely reduce value. I see all kinds of ads for used BMW's highlighting Dinan parts or MPPK but have seen VERY few ads claiming the cars have a JB4. The JB4 is certainly a much cheaper route to more power but MPPSK and Dinan parts don't potentially put your warranty in jeopardy and you'll never have to ask yourself if you should remove them before before a service visit or sale.

You can take off the jb4 when you turn in lease and just sell it. If you just leasing, no point in buying an mppsk and then turning it in. Unless you like throwing out your money. that's why I suggest the Dinan midpipe and leave everything else alone. I go into service plenty of times with jb4. They haven't said anything. Why would they look to piss you off, if nothing is broken or wrong. They want your business as a dealer.

Just adding a mid-pipe to a JB4 setup will I get you some sound with the resonator delete, although I haven't heard that combo. Won't get you any more power though while a catless downpipe will get you a fair amount of both. If you don't have emissions worries and are looking for the best bang for the buck power-wise I'd do JB4 + downpipe before JB4 + midpipe. As for going into service with a JB4, sure they won't mess with you if there are no problem. But if you have a serious powertrain-related warranty issue down the road and they are aware that you have been running a piggyback it could be an issue. In most cases you'll be fine, but it is a risk, especially with a new engine like the B58. |

Op is talking about adding it to his vehicle after vehicle t is built. Can't factor it back into the residual. Mppsk only adds value to people who know what it is. Which isn't much except a tune that is over priced and an exhaust which sounds terrible.
I was suggesting the jb4 because as just a stage 1.. it's the best bang. Plug it in and set map 1 and enjoy. You need EWG connectors for competition dp. And it's not smog legal. Midpipe will satisfy anyone looking for more sound and zero drone. Plus you keep the BMW valve. BMW can also not warranty you for Dinan. And Dinan can also void they own warranty. It's happened to a friend of mine. I think Dinan puts out nice hardware except their tunes suck. Last edited by PeterA90; 03-23-2017 at 11:35 AM.. |

How do you know his vehicle is already built? It's not at all clear from his post, and if he's leasing then it's important to know that the MPPSK can be residualized.
And the MPPSK sounds terrible? Pffft, ok dude. Vast majority think it sounds amazing. Exhaust sound is subjective but seriously, have you heard one in person? I've gotten so many compliments on the exhaust tone. |

This is honestly a stupid debate. It's 500-1000 dollars for 60+whp/60+wtq... VS 3+grand for barely 25whp/wtq and cf tips. He's obviously asking because he's budget minded. Mppsk regardless if it's residualized, your still paying for it. Over a course of 36 months... |

The OP is asking if the stock exhaust system need's to be cut for a mid pipe install? No offense intended but I wonder if he/she would be prepared to send Terry logs if they had an issue with the JB4? Does the OP know what a log is, how to get one and send it? Also I'm not sure of the OP's location but it may have a big impact on how smart it would be to install a catless DP when emissions issues are taken into account? There's nothing wrong with the stock exhaust and a JB+ or Dinan Sport might be worth consideration.

Yes one cut needs be done if you install a midpipe from either AWE or Dinan. It's very simple. Also I also recommend not touching the dp for emissions and smell. Jb4 on map1 needs no reason to send logs. Jb+ might be another good option. Dinan sport has mixed reviews, I've read. Jb+ is a set it and forget. Go have fun kind of ordeal.

However - the reason the JB4 did interest was due to the work being done on the fuelling - if they were to release a new map which somehow got around the fuelling issue - then the JB+ wouldn't be "upgradeable" whereas the JB4 would be (I think?). As an aside, has anyone done a sound comparison between just midpipe + stock exhaust vs de-cat + stock exhaust? I ran decat on my stock exhaust 235i (N55) for over 15,000 miles and it sounded brilliant - the perfect combo IMO |

https://m.youtube.com/watch?v=wOw2jjsyVgg. ☝🏻Here's the mppsk exhaust. That sounds terrible. Sorry. The only exhaust that make this sound good is AWE, REMUS, CG full valved exhaust or DINAN. If budget is a concern then competition dp to stock exhaust. If you don't care about my subjective view, then why are you fighting me? Because I was trying to help some not spend 3k on an exhaust and tune that only gives 26whp 👍🏻 And then you came along and I have to deal with you. Anyways I've already answered his question in pm so it's his money and choice. |

I'm not fighting you, and there's no need to apologize. I just disagree. Strongly. Since you posted a youtube clip with a car mostly still in a cold start and not under load I guess you've never heard the MPPSK in person. . . . . not a very credible opinion.

I'm not looking to argue either but where did you get the 26whp number?
This dyno says it's 37 HP and 45 TRQ. I did appreciate the link to the video but I have MPPSK so I know what it sounds like. http://f30.bimmerpost.com/forums/sho...304356&page=17. see post #374

My mistake. 3k for 37whp. I have heard it. I told you it's sounds good at WOT. I just don't think it's worth the pricetag...When there's better sounding exhausts for much cheaper. On top of tune which still retains the factory fuel cap...

Some people really dislike the sound of the MPPSK I'm very surprised, I personally love it and receive nothing but compliments. As far as power goes it produces less then jb4 would but with jb+ you should be up to par power wise.

I like the point of MPPSK and Dinan adding resale value as factory and pseudo factory mods backed by a warranty. Definitely a selling point for MPPSK. Dinan maybe a little less so if it's giving you problems and error codes.

Anyone who says they don't like it it's because they are judging from YouTube videos.... you can not compare at all between real world and YouTube...
I absolutely shock how good the mppsk sounds.. I listened for months and thought the mppsk was ok sound but real world ... wow |
