C63 no Secondary Cats

akreidie1 · 09-25-2009, 05:23 PM

I felt a difference with the throttle response, sounds alot meaner! I think there is more performance gain aswell, I'm gonna do a b4 and after on the dyno. I made a b4 and after sound rec and I'll post these too

did you have a x-pipe placed or just straight pipe? and did you remove the resonator as well?
thank you!

akreidie1 · 09-25-2009, 06:00 PM

No just sec cats and straight pipes

mzporto · 09-25-2009, 06:04 PM

Hummm... Euro-Spec C63 has no secondary cats... does it?

Jeffield · 09-25-2009, 06:16 PM

I m thinking if i should remove my cats too... i think it will be good but i wonder will it sound good

W204 C63 · 09-25-2009, 07:40 PM

i want to too. how much did it cost

akreidie1 · 09-25-2009, 09:30 PM

It's worth it guys, I payed around 400 but the sound is soo much sicker!

Sincity · 09-26-2009, 01:50 AM

I have been hearing from one member here and another in the BS forum that says no real gains. I sure like to see some before and after dynos to confirm one way or the other.

Unbreakable1 · 09-26-2009, 02:24 AM

we'll have answers this Monday

Jeffield · 09-26-2009, 03:06 AM

but wait, taking out the cats meaning you need an ECU tune so you dont have Error code am i right?

if you take out 2nd cats you dont need a tune. no cel's

patboyy · 09-26-2009, 05:31 AM

sorry guys...i dnt really know where is the second cat and where is the first car, and abt the x-pipe....i m new...so if there is a pic or any one can explain a little bit more on the exhaust configuration on the C63 will be very very helpful...thnx

Sincity · 09-26-2009, 12:28 PM

The first CAT is where it meets the exhaust manifold at the engine. The secondary ones are located downstream about half-way.

Sincity · 09-26-2009, 12:31 PM

If there is a gain, I am going to swap out the secondary CATs with T304 SS resonators from Vibrant. They make one with a 9" body and overall length of 12" that should fit.

Jeffield · 09-26-2009, 03:26 PM

but dont you only gain if you get first and secondary cats?

patboyy · 09-27-2009, 01:19 AM

Now i know, So is it only AMG has the first CAT? how abt Bimmers?

btw, does Kleemann K2 package will deleted the first CAT? and do they supply secondary CAT as well?

10104074 · 09-27-2009, 09:43 AM

I'm going with custom long tubes and deleting both cats. I already have the Kleeman ECU tune. I live in a rural area whwre emissions are not part of vehicle inspection. I'll post dyno results when complete. I'm also going with the Quaiffe LSD. Couldn't see spending the extra for the OS Giken and it is a clutch type anyway.

exdes · 09-27-2009, 01:20 PM

Where did you get it done?
Possibly looking at deleting the 2nd cats and resonators..

10104074 · 09-27-2009, 01:32 PM

It will be done at MVR Motorsports. They also have an arm called" Racing Solutions." They are in Bridgeport, TX. They have not completed the work yet, so we'll have to wait and see.

I had Scott @ http://hi-flocustom.com/home.html put in some resonators and change the tips on my Ultimate racing exhaust on the 335. He is more than capable of cutting out the secondary cats and replacing it w/ a straight pipe. His prices are very reasonable...did I mention he drives an AMG?

Sincity · 09-28-2009, 10:51 PM

Before and After dynos ready yet?

Brian GT PRO · 09-28-2009, 11:55 PM
