So I recently did my catted downpipes on my 2011 335i "e90" + muffler delete and I noticed previous owner delete second cats now is way to loud especially in cold start plus bad drone any suggestions.. what's the best option? Thank you

1- putting back stock muffler
2- add some vibrant resonator and keep the muffler delete

What's about the sound? a would be louder with the downpipe or pretty much the same ?

whats your question?

if the car will be louder with the stock muffler with a catless downpipe installed?

uh yeah

So, you have catted downpipes & straight pipe all the way back to the bumper? You have the stock X-pipe in there?

You want to quiet it down?

I'll sell you a set of stock mufflers for $150.00..
