So I plan on putting dual electric cutouts on the c63 (gonna get them from QTP since I need them to be wireless)....

I also plan on deleting the resonators and secondary cats.

First Question:

I know GT Pro used to make a nice kit, but I see they are no longer in business (at least their website doesn't work anymore). Who else besides MHP makes a good kit that deletes both the resonator and 2ndary cats? Should I just have my exhaust shop (which does good work) fab it themselves as this will be cheaper?

I'd love to know which companies produce a kit for our car.

Second Question:

For those of you that have cutouts on the C63, where did you place them. Any pics/videos would be great. From the pics I've seen of the way the exhaust is routed, I think the best place will be to put the cutouts right underneath the rear seat area where the pipes separate, but I'm not sure if there will be enough room.

Thanks in advance for your help/advice!

I lied...have a third question haha...does deleting the 2ndary cats require 02 sims to be used to prevent codes?

Nobody???

I deleted my secondary cat. No issues. But man cutout on this car would be crazy loud.

Thanks....so no O2 sims needed...good news....I had dual cutouts on my SLK 55 and it sounded AMAZING...had magnaflow resonators installed to get rid of the raspiness...

I can't wait to get the work done

The resonators are a flow through design with not restriction. It's just a sound thing. Some say it looses it low baritone rumble while other say it increases the higher tone bark and wraspy sound.

I was gonna install this on my car, but decided not to. If you decided to go for it, I think you should install it before the second cats. It's gonna be ridiculously loud though, but i guess not as much as LTHs.
