HELP!! CLS55 Resonator Delete/Secondary Cat removal
Cold start after resonator delete and secondary cats removal...
I paid 325$ for this set up, its cheaper if you don't get x pipe though..
Next time I am driving past a tunnel I will record the sound it makes.. What I love most about this mod though is that its not some ghetto Honda loud exhaust when even when your at a red light you can here it idling or droning, its nice and quiet like before when stopped or at cruising speeds its not to loud but has a nice aggressive tone to it, but once that pedal touches closer and closer to the floor, the more you'll hear "OMG what is that?!?!?" from the other cars around you, and at highway driving I love when you accelerate because you can now actually hear the exhaust from inside the car , sort of like my old Jeep SRT
Headers, NO cats or resos and stock muffler

How loud does it get inside the cabin at cruising speed compared to before? Are there any drooning sounds (low vibrating sounds) that will hurt your ears if you have to drive for a long time (1-2 hrs). Thanks.
Did the shop custom make your x-pipe or you purchased online through a shop?

Cruising speed you will not hear a thing just like before(15-50mph)inside the cabin, but if you are on the highway going about 60-100mph you will hear just a bit but when you accelerate you will hear a very nice and smooth groan of the car which is not loud at all but a more relaxing and comforting sound lol , it does not drone at all at any speeds, nor does hurt your ear, and yes the shop made it themselves , google around for some good muffler exhaust shops most of them will carry there own pipes and can do the work for you the same day you schedule without ordering anything special, unless thats what you want
There are no sensors on the secondary cats, only the main ones.. if you get them all taken off then yes you will need to get it tuned so CEL will not show anymore
I have had my resonator deleted and was looking to get the secondary cats deleted? (Where are the 1st placed?).
Does this allow for any pops and bangs on over-run to come through? I miss that from my TVR and wondering if I can replicate.
Thanks all
The primary cats are in front of the secondary cats (going in the direction of the engine). I would only remove those if you are installing headers.
