Question for people running catless downpipes

N54bimmer · 10-13-2011, 06:38 PM

I want to get catless downpipes, however my main concern is the dealer.
I am still under warranty, and it would be a shame to loose it, the problem is that it is way too expensive to have a garage put them on and off every time I go in for service, and Im sure the dealer would notice I had them installed since I remove my procede for dealer visits and then the cel will appear if procede is taken out.
So what do you guys recommend? Should I risk the dealer visits and leave my dp and procede in on map0 to avoid cel.
Should I have a mecanic put them on and off every time I go(keep in mind Im only pwertrain cpo warranty no maintenance so its not too often)
Or should I just get a catless exhaust which wont throw any cel and call it a day?
Thank you

Usually if you are going in for maintenance or routine service leaving DPs on is not an issue. I personally would only remove them if going in for major engine related warranty work.

Pull the trigger especially if u don't get engine trouble often. Castles DP make a huge difference

Will they void your warranty if found? Yes. Will they look for them on a normal maintenance check up? Probably not.

Your call.
