Downpipe Videos

Can some of you share videos of your N26 with Catless Downpipes and Stock Exhaust and/or JB4

I have a buddy who has that setup but has BM3 instead of JB4. I'll try to get him to take a video.

n26 is special because it has 2 resonators instead of 1 for the n20
cold start will sound loud but when operating temp will sound just like stock.

What do I need to do? Remove one or the other of resonators? muffler delete? I'm not aiming for an obnoxious loud tone but definitely louder than stock. Would like some burbles and loudness at acceleration (note: i have a 435i muffler installed at the moment)

i have not done anything after the cat but my plan was to cut off one of the resonater and see if that helps open more. But ive been saving for a awe catback.

I believe Phil2theJay can speak to this.

Put it this way operating temp sounds like stock bro maybe a slight difference but hard to tell

I'll get a video tomorrow

Cold starts fucking suck, they aren't your normal loud it sounds like a lawnmower having a spazz attack it's so retarded honestly. That second cat and res vibrates so much it sounds like someone put a spoon inside a glass jar and stuck it in front of a loud bass speaker. Rattles more than anything

I'll wait on that video before i install it around 3:00-4:00 hopefully you'll have the video before than. LOL it's that bad? So besides the HP gains it doesn't sound good at all? I'm assuming nothing like a 435 with downpipes.
Will straight piping the sections where the resonators are change what you said?
