Hey guys!

So recently I got some bolt ons installed alongside a JB4..

- CTS Downpipe
- VRSF Intercooler
- VRSF Charpipe

I also have the stock M performance exhaust system.

The catless downpipe definitely boosted the sound and the cold start sounds absolutely amazing.

I have the resonator and muffler as well.

I am wondering what can I do to improve the backfires and sound? Not looking for some riced out sound, but I definitely want more aggressive sound.

I've heard that the catless downpipe alongside a muffler delete sounds too raspy and drones a lot.

Any advice is appreciated.

PS: browsed pretty much all N55 exhaust videos on YouTube, really hard to hear from a phone speaker, was thinking if anyone actually had experience and advise to share.

Try flash tune? There is burble option to make it sounds a little more aggressive?

I'm on extended warranty for 6 more years. That's actually the main reason I went towards the JB4. Less likely to be spotted if ever a warranty claim.

I've heard the Remus exhaust is a bit more aggressive then the mperformance one. Going to go with that myself as I currently have catless/muffler delete and there is too much drone, although the cracks and backfires are crazy. Not sure the switch would be worth it though just for sound.

do you have stock m exhaust with black tips or the m performance one with chrome or carbon tips that is port installed by bmw.
