decat

I know this has probably been asked a million times before, and I did a quick search but only found out bits from the bigger engines. Any how, I am thinking of decatting the Derv, can has anyone done this on these? I am lead to believe it has two cats on these. I rang up about having it...

Hi all. What are your thoughts on getting rid of the cats & getting it remapped? I've been told it'll sound & go a lot better

Hi All the car I got has full decat system and is brutal... does the E55 have 4 cats? does this mean all the cats have been removed off my car.... as I was led to believe the modification resulted in 2 CATS still being present. Anyway the reason I ask is because its got an almighty roar.... and...

Will a de-DPF'd (cat to petrol types) pass a 1998 type MOT emissions test, assuming its still basically running ok?

Well had the heavy, lardy resonator removed today ( Cats already removed ) - & straight stainless steel pipes added - difference is much deeper burble and actually sounds like a v8. Not much drone coming through in fact at gentle speeds you'd not even notice it had been done. Certainly deeper...

Just collected a 2011 C63 Estate with PPP. Thinking of decat options and have seen that Longlife Basingstoke are recommended on here. Anyone actually had their C63 in with them and if so what are thoughts on best option - x pipe or y pipe? And any known power gains or is this more for...

Hi All, Well after much debate... today i finally chose to have my E55K exhaust secondary de-cat and resonator removed (replaced with straight pipes). Luckily was able to use existing balancing pipe (close to cat) cut and re-welded (see pics) I was concerned the car would sound too loud after...

HI all, im new to the board and Mercedes so please bear with me. i have a 54 plate C200 cdi, i struggled this evening to get the CAT's off and the second one seems blocked. can olly or someone supply decats, or indeed cat i decat it for the MOT? or just cut em open and empty them? cheers all...

Since owning my CDI I've been itching to remove those two big cat's under the car to unleash a bit more power/sound out of that beast like 3.2 engine. At first, I was planning cutting them out with a grinder and welding in two straight bits of pipe in their place, but, I found a company on...

worth doing? I know it a quick and cheap mod, better sound and a small performance gain but will the cars ecu need mapping? and how does it affect a MOT? I await your collective wisdom!

Just heard Olly is out of stock :doh:

Looks like I have a primary catalyst start to collapse so a primary de-cat looks on the cards. Anything I should be aware of ?

Hey - in south england, UK - need to release the sound of my V8 asap! Any ideas who can perform this task? cheers!

Watch with a decent PC speaker system!! ‪MERCEDES C55 AMG 5.4 V8 X-PIPE + DECAT EXHAUST UK‬‏ - YouTube After seeing the recent Y-Pipe decat being added to a C55 on here that finally spurred me on to get my X-Pipe made & fitted, I went for the X-Pipe crossover with 2 x 2.25" (rather than...

I have made a de-cat pipe for the 210 E55 saloon. The sound is wonderful and quality is perfect as usual.

Said I would be back to give some impressions after a (2 x 4h) weekend drive. The sound of Olly's secondary decat and resonator bypass pipe is fantastic and the missus loves it too :bannana: The slight drone in 5th between 2500 and 2800 rpm is not intrusive and doesn't bother me. I guess my ear...

I thought I'd let my fellow C32 owners know how I'm getting on with my exhaust conversion. I know earlier AMGs are supposed to be a bit Q-car and a bit of a gentleman's express but, having heard a C63 at full chat, I decided my car needed a bit of a voice. So back in February I took it to Olly...

We have just made a de-cat pipe for C55's It sounds truly amazing.

hi where is the cat on a 97 c250 td, thinking about gutting it, or replacing it with a replacment pipe, anybody got one of those diagrams to find it expected it to be on the downpipe, nothing there.. theres two boxes a small one and a large one in the middle of the exhaust system, is one of...
