The only ones I'm aware of for the N55 are the Wagner w/ the EUR6 and Fabspeed. I don't even know if they make N20 versions.

Safest in the means of no risks of creating problems to the car. sorry not really specific.

I think everyone will have a different opinion here but I think the N55 sounds best with a catless downpipe.

I bought a used M2 muffler for $200 and paid $75 to have it installed. Sounds and looks great.

Can you post a sound clip please?

Love my autowerk axle back and resonator delete. Sounds great and I haven’t even added my CG precision catted dp.

Yes can you please post sound clips

I unplugged the flap in the open position and am happy with the result. A catted downpipe is next, but the sound as is, is great.

Are you able to take your stock downpipe and increase the flow? as in change the cat or make the cells bigger?

Yes I've been running MPE + Res delete for a while now. It's nice and definitely don't regret it, burbles and is a bit louder. But still not loud enough after 6+ months I want more sound, so I decided to order the CG catted downpipe, coming in a few weeks.

let us know if you hear any drone once you add the upgraded DP.

I've read a few post mentioning some drone with the res delete.

Congrats on the CG precision! Are you the dude that also bought through Ecs tuning who is charging 300 less than CG?

Will do. I was thinking it wouldn't be as bad since it's catted instead of catless. I've seen confirmation of drone with catless but catted is slightly quieter.

Yep, ordered from ECS and CG is custom making it since there aren't any in stock. I will be having that and KW Street Comfort coilovers installed at the same time
