The first thing I noticed is that I can hear the turbos spool and whistle now. Which I think is very very cool. The 2nd thing I noticed is that my gutted muffler now sounds very very different. My CEL hasn't tripped yet. How many miles will it take to trip the CEL? I commute 80 miles a day round trip in rush hour traffic so I will report out later if their is a drone or any gas fumes in the cabin. So far...im digging it! Can't wait to dyno it. |

This is so tempting to get a set of DP's, but 1-3 g's for some piping and flex is ridiculous! That's without labor, I wouldn't even attempt this install with my giant sausage fingers lol. But in all seriousness, I got to hear and feel the difference between stock on JeSTs' beast and all I can say is wow! I guess I'll just wait for 1 of you to get sick of them and buy them for half price lol

Their price is very reasonable compared to some of the other distributers. http://store.ultimate-racing.com/col...m-x6m-downpipe

lol, cause theyre worth it. I didn't want to see you spend more $$ on another brand when they produce the same end result.

Hopefully a used set pops up on the forums. Pricing for exhaust parts on the X5M is outrageous. I purchased Macht Schnell pipes for my 335i back in 2009 for $400 new. The D Pipes were the same size as the X5M/// aftermarket pipes and the quality was top notch. Somehow exhaust parts receive an insane M/// tax and its deemed acceptable. 5-7k exhaust systems and 1-2k for scrap metal it absolutely outrageous.

I already have a tune and I'm just itching to get a set of DPs to take it to the next performance level. I also want a carbon front spoiler and rear diffuser too! Gixxer - has to wait on one or the other, so is wondering what element to focus on first - Performance or appearance? |

Its very very loud for 45 seconds on the idle cycle but then it tames down to a acceptable decibel level. The truck feels incredibly responsive and savage. I more than recommend catless pipes for the performance alone. That being said the sound is incredible... rev matching sounds great and the car just rumbles when under load. When im cruising at normal speeds the sound isnt too loud, very comfortable. Dont hesitate to install these, you will not regret it. Also the smell is unnoticeable for me. Some times is get a whiff of odor but nothing obnoxious, i think the other guys are a little sensitive to the smell ha. |

I agree 100% and can confirm everything that StatenEye just said.
Simply incredible.

So neither of you two (StatenEye or the Dr.) would go back, now that you have experienced catless downpipes? Am I also correct to say that you can actually feel a significant performance difference?
Gixxers new AA downpipes awaiting install for about a month now.... |

I would also say that there is no way I would consider going back...
You just can't beat such a significant boost in performance while at the same time reducing stress (back pressure, ...) on the turbos and reducing engine room temps, improving MPG, .. etc. Besides, sometimes you really enjoy that ROAR when you get on the gas to totally blow away some ricer who pulls up next to you! In contrast to infamousdiz, I do not find the exhaust note obnoxiously loud... maybe diz has a complete catback exhaust system too? My exhaust is stock and I strongly advise against any modification of the stock system. Finally, believe it or not, if I were to choose between just a tune and DP's, I would go DPs, but then you would have to deal with the CEL. Therefore, tune + DPs is the way to go, no doubt about it.

I agree with a few posts on there that the ///M tax is stupid, so I've been spending more time on F10 M5 boards to see what they're doing to mod cars, prices they're paying (assuming they mod more, therefore prices may be cheaper) and came across pipes that are actually priced they way something so simply should be. While the buyer said they had minor fitment issues, they installed the resonator style pipes, but I'm going with the non-resonator style - http://www.ebay.com/itm/131535510483...%3AMEBIDX%3AIT I'm sure it's nothing that couldn't be solved by an exhaust shop can't adjust as needed when they're doing the mandrel bent piping for my muffler delete. At $225, 5 +/- hours of my own time, I think they're worth a try vs their $1600+ counterparts. Damn that ///M tax!! Now to find an intake system much like what MSR makes for the F10 M5 with that ///M tax...

Fitment is very very important. Even with the catless downpipes that were made for the S63, it still took me a very long time to line everything up. Its a very tight area to work in so be prepared for bruised knuckles along with tons of swearing. Some of the bolts holding the OEM downpipes are not visible so you will need to go by feel and a swivel socket joint. I hope this doesn't discourage anyone from attempting to DIY but be warned to set aside at least 4 hours to do the job. Maybe faster if you have a 4 post lift and can completely walk underneath the car.

4 jackstands at the stock locations will also get the height needed to do just about anything. I did a coilover install as well as a full suspension and cooling system rebuild this way just before Bimmerfest.
