As the title implies, I'm trying to learn/find out about downpipes. I currently have an MBRP catback on my '16, but find that while nice when normal driving, when going wide open it's just too boomy. Now having realized this about 6 months ago, I purchased a Mountune catback which sits in it's box in the garage. Now I'm preparing to throw it on the FoST real soon, but then got to thinking. I should have ponied up the dough and purchased the catback with downpipe combo for a big discount. So I'm thinking about ordering the downpipe from Mountune. I like that that setup in that it doesn't get to crazy loud. Here is where I'm looking for advice.
I noticed there are options for catted and non-catted downpipes. What are the differences, and what is needed in order to put these in? I would tend to believe that O2 sensors are involved amongst possible other things. What I'd be interested in would be the least amount of hassle to install from the standpoint of not having to start bypassing sensors, or anything of the like. Now I know that I'll have to get a tune revision, but am I OK to go the turboback route without a FMIC upgrade? That mod will be coming next BTW.
