Can you give me a close estimate on the gains I could expect from the following mods, with and without a tune.
catless downpipes midpipes axel back fmic How much total horsepower would one have with these mods. |

how much horsepower is kind of a relative question. dyno type, weather conditions, altitude, etc etc etc can all have an effect on horsepower figures. here's my best attempt at an estimate: with a tune, 350-420 wheel horsepower without a tune, 300-340 wheel horsepower as you can see, a tune is really required to get the most from your mods. catless exhaust, intercooler, etc will net you some power at stock boost levels, but the increased capacity for higher boost really should be taken advantage of. |

midpipes, not as high. i still have stock catted midpipes, i think they'd only be worth 10-15 whp at most |

I thought catless downpipes would be around 30whp. Maddad promises 10whp for their resonated midpipes on a stock car. Do you think for a full turbo back exhaust 40whp gains could be expected? I know there is next to nothing for the axel back section except for weight savings.

I think it really varies on how efficient your DP's run etc. The dyno test are varying out there, but maddad did get 10-15hp gains with addition to the midpipe, i have seen the dyno runs and think they are posted on the site too. Go catless, you will feel the difference. I just switch AR catted DP's to Macht Schnell catless and it was a world of difference...no dyno yet.

you'll see and feel a difference when going catless. unfortunatly, you'll hear it too.
the other benefit to catless and doing an axle back, huge weight loss, which you can feel too, even if there were no gains. But i wouldn't be surprised if you did 40whp difference with a tune and catless. running an aftermarket FMIC on stock boost is a waste of money the stock system is optimised nearly perfectly for the stock system and tune. If you swap it out, you'll maybe get 1 or 2 hp, but you'll gain 10lbs at the front of the car. and lets not forget, you're paying between 400 and $1000 to gain 1-2 hp when you aren't tuned. |

On the 2010 135i there is no removable elbow on the charge pipe to install for meth bung application. any idea how people are handling this situation? are people removing the charge pipe and drilling if for meth bung? any remedies?

so their claim could be pretty accurate about no power loss. or at least minumal. no matter what, a resonated will still produce more power output then a catted aftermarket downpipe. only difference is, you're going catless, but don't get the volume of catless. |

Not sure about the resonated versions.

I have heard of a few people struggling to fit the catted downpipes before, but i guess you just have to wiggle around a bit and eventually they will sit properly. MS has a slightly lower price point the AR as well. I have the AR sitting on my living room floor, they are beautifully put together, so i don't regret my choice, but I'm certain the MS people will say the exact same thing. I went with the AR because they seem a little easier to get your hands on. there's lots more venders carrying them. Including a local Canadian vender, which solves a few problems when avoiding the border. |

This is the only information I can find on the net about the AR resonated downpipes. I can't find any reviews on them or pics of them installed.
What are your thoughts on them - http://n54tech.com/forums/showthread.php?t=9805 Do you think it's possible that there may be some power loss instead of getting standard catless? |

instead of 30whp, you might get 28 or 29, no dyno is going to pick out the difference. A catted aftermarket downpipe might be good for about 20whp, so the resonators are definitely going to be much much better then the catted version. |

one more thing to point out, catless without resonators can have a bit of a "rhasp" sound. The resonators will or should get rid of that.
another solution to consider is the resonated midpipes that i think mad dad makes... just something to think about as an alternative. |

but exhaust and tune on a turbo are the most effective power makers in my opinion, followed closely by intercooler. I don't have much experience with meth injection, but from what i've seen/heard, you're looking at another 20-30whp there. add everything all together and you'll be looking consistently over 400whp, especially with meth, you'll be surpassing 400 with ease. your ultimate best results would be catless, resonatorless, and mufflerless, like the AA exhaust which just has basically a sound baffle off to the side or the mad dad mufflerless axle back... which basically has resonated tips i believe. |

ohhh, missed that.... Bryce might have a better idea then I. I haven't really researched any Meth stuff really.
However, you could drill it, but I always fear shavings going into the intake and becoming debris stuck in the cylindars. good way to get precognition. I would definitely recommend trying to find a way to take it off, might not be easy, but worth it in the end.... I'll try a quick search and see if anything comes up, but you should know, i suck at the internet, and am very poor at searching I can find porn easily when i need to though!!! |
