Re: so i put a turndown/side pipe on my jeep.
if they can link the missing muffler to any warranty repair it is in for they will charge you for it. if they can't link it to the problem...they may void your engine's warranty anyhow. i'd put it back on for now.
btw how did it sound? maybe try doing the turn down after the muffler if it was to loud/"poppy"
