I went to a local shop yesterday and had my resonators removed and replaced with straight pipes. The car's voice is now very- deep and MUCH louder, to the point doesn't really sound like the old AMG roar. I also notice it's using more gas than before.

Another very helpful member advice I remove the 2ndary cats also and replace them with an X-pipe to tone down the deepness to get back the original AMG roar.

So if I do that, will my car be ALOT louder than it is now? because i think the current resonator delete is already loud enough but way too deep and not smooth. Will removing the cats also worsen my gas mileage than it already has?

Thanks guys

i think ur getting lower gas mileage because your staying at a lower gear stepping on the throttle more to hear your exhaust. thats what happened to me after i got resonator delete and secondary cat delete. i wanted to hear the exhaust more

hahah you're probably right about the gas mileage part, it is very tempting to step on it more often now. I try to drive in Comfort Auto to save gas, but the car sounds too deep and weird. Starting to sound like american muscle when I rip it in comfort auto.

Sweet sound!! is yours straight pipe in place of resonator and straight pipe in place of 2ndary cats?

The resonator has three clamps but I think the left rear is one peice all the way to the muffler. Did they cut it and you a slip clamp or weld it in.

Sound bad a$$! congrats
Does a resonators delete have any added gains in performance?

c63addix

The guy just weld it in

Nope just sound

theturkster

Cool thanks

I did exactly the same as you and I don't like the sound. I am waiting for my X pipe to arrive and I hope it smooths out the sound! I'll let you know when it's installed.

I think it sounds great.

Removing the cats and replacing with an X pipe will add power and smooth out the tone.

thanks dude, I ll be adding xpipe this coming weekend i'll post another vid once its done !

Yea people been telling me that; but will I gain much more sound from my start up and low speeds than just the resonator delete.

jsc1234

yes whole thing is straight piped

Yup, that's pretty much why I set off my neighbor's car alarm off everyday I LOVE blasting through tunnels with that sound. I'm always torn between fuel economy and juvenile fun.
