Any members with the aFe Twisted Steel Header/Down Pipe (48-36310)?
Hello people, I'm still under manufacturer warranty (just 700kms on the odometer) and in my country, the BMW dealer is very very strict when it comes to voiding warranties due to modifications.
So I'm thinking on this Down Pipe WITH cats: http://afepower.com/shop/details_new...0L&&brandID=99 What do you think guys? I know that gains won't be "too much" but since I'm not doing any ECU modifications (piggy back, JB4), I'm currently just thinking on giving my ride a better exhaust sound (I have the Performance Exhaust installed) and a little more performance. Thank you as always for your comments. Last edited by AlexGT; 10-14-2014 at 10:28 AM.. |

Well, it will give you more sound and more HP/TQ over stock. If that is all you are looking for this will bolt right in. Shop around for price as I have seen them on sale from time to time.
As an example of good price, http://www.gotexhaust.com/i-17346477...down-pipe.html |

I have MPE with 200 CPI sports cat. With jb4 maps 2, 5 and 6 goes hard and sounds great! Dealer not bothered as it still has a cat installed in the exhaust, in fact service guys like having my car in as it's got other tasty add-ons....... Pave

Now, a question, is the down pipe hard to install? I'm not thinking on doing it myself, but I could use some pointers regarding how hard/delicate is the installation in terms of how tough is to get to the OEM down pipe, remove it (the sensors, etc). Is it difficult enough so it might be dangerous for the sensors or other components? Sorry if my question sounds silly but knowing this is crucial for making the purchase decision. Thanks Pave |

The install was pretty easy, its pulling the OEM off that was a PITA for me. It took me 1hr to install using a lift and compressor tools, It was a learning curve figuring out what needed to be loosed up and pulled off to get at everything, 45 minutes next go around. The lift was crucial in this happening in 1hr vs 2hrs or more on jack stands.
Getting sensors off is no big deal, particularly if you have a 02 sensor wrench

I'd be very curious to learn what the CPI of the stock CAT is. I think 200 cpi might be the sweet spot to see gains and have some cost justification for a catted downpipe. Of course then we have to worry about setting off a light because the O2 sensor is seeing something is doesn't expect too (yes, even catted DP's have the risk of setting off the light).

I have BCS 200 CPI cat DP. Jb4 in stock or bypass modes no cel. Wagner tuning website confirms their 200cpi DP doesn't trigger CEL. Whereas Bastuck 100 CPI DP do confirm it will trigger CEL. |

All of your examples, are they catted downpipes for the M235i/N55 platform specifically? I do not see a catted DP for the M235i on Wagner's website.

I'm going to be purchasing the 200cpi catted downpipe from Wagner tuning, less restriction and they guarantee against cel's. $650 too.

http://www.wagner-tuning.com/Downpip...cat_p_112.html That is the 200cpi catted downpipe that fits the M235i. I spoke to them and they claimed to have '55 on backorder' and they expect to ship mid-November.
