secondary

Hi All, I am sure this is probably a Repost but I couldn't find anything as I am a bit of a Noob at Forums! Couple Questions! I am thinking of buying the Miltek Secondary Cat Bypass off Ebay, Does anyone have this on there car? Does it make much of a difference in how loud it is...

In addition to the pair of back boxes I have I also have a pair of exhausts from secondary cats back. Let me know if you are interested.

Hi, If any ones has the Miltek Secondary cat Bypass Exhaust let me know, or just a Decat for the C63 Cheers

Hi all, I have had the secondary cats gutted by a fabricating company local to me in West Yorkshire. I don't know if it will work or not but I have saved the photos in photo bucket and attached the link below. It was a sod to get all of the stuff out of the cats and it took a couple of hours to...

The electrical connector to the little electrical coolant pump on the inner wing has corroded and broken off. I'm going to get a new connector made but is it ok to drive with the pump disconnected in the meantime? Thanks

I have the centre section of the exhaust system for the w202 c43 amg I will upload pics tomorrow when i get to my workshop Price-£150

I've noticed the electric pump in the tank runs continuously when the ignition is turned, is this normal or should it cut out when its up to pressure? Cheers!

Hola - Has any one had any experience of using EMP performance in St. Albans for a secondary cat delete? Quality of workmanship, steel used, etc? Also is anybody local to the Ascot area with this modification carried out so that I could have a listen to on a C63 before I commit to this...

Hi, I'm fitting some manifolds and having a straight through mandrel system made with x pipe etc to join where the resonator goes, so the whole front end of the system is up for grabs. Can split apart for cats or resonator etc. I'd even consider selling the whole exhaust system if there...

Has anyone done this on an E63 6.2 W212? I am looking for a little more sound but nothing in your face. EMP Performance say it increases the sound by around 10-20% can anyone confirm the difference pls or direct to a youtube vid Thanks

Hi All, I've been doing a lot of research on gutting the secondary cat this morning and it seems like a good mod to go for. I'd prefer cutting out the standard cats, gutting them, welding back together and putting them in over an X Pipe or other options. Would anyone know a good place in...

Ok I've read many posts and watched a fair few videos which have answered pretty much all my questions bar two. How much does this mod cost ? Is there anywhere in the Oxfordshire area any members can recommend to carry this out. Many thanks in advance.

Hi All, I am looking to remove the secondary cats on my c63 and replacing them with milltek bypass pipes. Wondering if something like that needs to be declared to the insurance at all? the second cats as far i know dont do much? thanks

Howdy, Anybody got (or had) any experience with these Chinese SIP's? I need one for my CLS as it's failed (swapped the relay, no joy) They're cheap - but question is whether they'll fail again in another year or so? :crazy...

After reading loads of threads on the subject it seems clear that a secondary cat delete should mean a fail, but is that the experience of those who have had it done?

Hi All Check engine light appeared last week, quick test on STAR pointed to Secondary Air injection system. When I first bought the car within 3 months I had the same error and a replacement relay sorted that out. This was over 4 years back. MB carry the Relay in stock which I will pick...

Hey guys, Since there's a recent trend in the number of Cat deletes, thought I would chuck in my tuppence worth. After some PM ping-pong with Robin (H20 MRV), I decided to follow suit and go down the Cat delete route - its actually more Cat gutting as Felstmiester has also done.... So on...

Slippery slope started in regard to modifications so, for the £400 I've been quoted to supply and fit the Milltek pipes, are there any better options to consider? I'm after a no-cut solution so that the car can always be returned to factory standard which I'm lead to believe that Milltek...

Hi all, I've watched loads of videos of people who have removed secondary cats and or resonators. To me, personally, a lot sound really raspy and un-refined, more like a shouting car rather than a deep rumbling puuurrrrr like the original C63 sound. I just watched this video, I think, going...

Thought that I should share my experiences getting the secondary cat delete done on my 507. Basically I wanted a bit more noise and agree that for some the C63 may be loud enough but I loved the sound so much I wanted to free up a bit more. After researching for a while, consensus from people...
