W208 resonator removed
After much delay I've finally had my resonator removed. I must say it is an improvement. It's not a huge difference but I can tell. At idle & start-up the exhaust has a deeper rumble. Under acceleration it sounds even better. I'd recommend it.

You should also have your 2 rear cats removed as well. It'll sound a lot more throatier.

Damn bro' are you looking for trouble? it is an immediate fine if you even ask a muffler shop to remove your cats completely.

i've had the 2 rear cats and the resonator removed out of my car for almost a year now..... passed smog without any problems.
yes, it is illegal, however, i believe it is illegal in California to modify ANY part of your exhaust, including the resonator.... so if you are going to do something illegal, you might as well go all the way and get the sound you are looking for =)

i could never live in CA. too much red tape. everytime i think CA is pretty cool i read something like that. so they will technically not let you alter the factory exhaust at all? even if you are replacing factory cats with hi-flow cats.

that is not too bad. i just changed the muffler on my w209 and the car sounds great. the w209 has a 3" mandrel bent exhaust.

Any sound clips? My car is at the shop right now getting the resonator delete, might do the secondary cats at the same time. How much did you guys pay for the resonator delete?

Removing your reso will only lighten your car and give it a nice throaty exh sound. No hp increase there,but a nice weight saving mod to say the least!

Ahmad if you delete the secondary cats ,replace them with high flow metalic cats. Only get rid of your primary cats,this is where the hp bottleneck is. You'll hear what my car sounds like when I bring it down to Maryland.

Did you have any problems with the ecu reading a different back pressure by any chance? I'm thinking of doing this but don't want to receive any errors or codes. So just take it to a muffler shop and ask them to take out the resonator? Do you recommend the supersprint resonator or just delete the resonator and save the money and still get a nice sound? Any info helps
Thanks
