decat

So I'm having a chat with my mate about cats. He insists that you can just bash out a metallic core cat and to check any TFSI forums. However, when I look down my *ina special sports cat, it's clearly metallic, it feels solid that any poking at it will only bend the rolled up sheet of metal...

I've not been on the forum for a while but just happened to read through yesterday and felt I needed to post this really. I've had my car tweaked at Infinit, facelift RS3 (18) and the service has been absolutely second to none. I actually went to see him after the original Boycott page was...

Hi all, just purchased a Audi S4 B9 Avant, its my first audi and moved over from Bmw (M4, 330D, M3 E46 etc) im looking to mod the car and ideally after decat - miltek preferably Intake Exhaust system - cat back or full inc decat Bigger exhaust tips - looking for slightly bigger tips if no...

Hi all, As the title, I have the above part up for sale. Seeing as they retail for £670+s&h, I’m wanting £350+s&h (£20 due to size and weight with paisley freight). there is an ever so slight mark in the metal weave that goes over the flexipipe to make it pretty, but it’s cosmetic only, not...

Iv a prefacelift tuned stage one by Rick at unicorn, just secondary decat and intake pipe, running 420 and 450ft/lb Is it worth the money to buy Down pipe and intercooler for the noticeable gains you get back? I will most likely never track the car. I know these suffer with out an intercooler...

I recently got a new custom catback exhaust which sounds amazing, but I want even more noise now, Im addicted! I am already stage 1 with pops and bangs from unicorn and am more than happy with the power output, but to get more noise my thoughts are turning to a decat downpipe. My question is can...

hi, has anyone got a cheap unbranded downpipe and are they any good? Found one for £140 which is stainless steel and has mandrel bends so surely it can’t be that bad as it is just a pipe at the end of the day? cheers

Hi all. Hoping for some advice please. I am in a dilemma as I have taken my S3 for a stage 3 tune and they have now contacted me after fitting the turbo and intercooler pipes to say I need a different exhaust. I thought having the standard one decatted was enough so don’t know why they didn’t...

I'm currently stage 1 with a res delete and pops and bangs mapped in, but I want something louder and more aggressive. Do I go milltek non res non valved catback? (Although would this drone be too much on motorway?) Or do I go decat and therefore stage 2 (with more pops and bangs) , plus a dsg...

Hi does anyone know if the car will pass it’s first mot with secondary decats in? Thanks

Okay so I'm currently running the stock exhaust with res delete and pops and bangs added in on a stage 1 map... but I want more. More noise, more pops and bangs, yup I want to be anti social when I put my foot down. Question is do I go full catback exhaust system or decat downpipe and...

Probably my second post here :) relativley new to the forum and being an Audi owner! I am considering a decat option for my 2010 S3 8P. The car already has a Miltek Cat back system and is stage 1 re-mapped. Looking to get the forums opinion on decatting. Pros / Cons and even better some...

Hello All, My garage have told me the downpipe is badly corroded and is in need of replacement, I have already spoken to Pipe Werx and have a complete system price, however my concern is having to drive from the west coast of Scotland to Ormskirk for the 500 mile journey. I was looking for...

Hi gents, 2 weeks ago I did a Stage 1 APR map which has really brought the best out of the car performance wise. 1 week ago I did Decat Downpipe and Secondary Cat Bypass (Secondary Decat) on my Sport Exhaust from Rogue Performance here in South Africa. I have scoured the forums for opinions on...

Hello new to this section Iv got a 2017 S3 just wanting to know if anyone has moved from a facelift or pre S3 to an RS3? Any pros and cons or doing so ? Also I’ve noticed the secondary cat removal is popular if this is done will it still pass MOT?

Hello, the other day I removed the two back boxes of my 2.5tdi in hope to get that v6 growl, but it hardly made any difference in the sound. Would removing the pre-cat and 2 main cats make the car louder? (I dont really wanna remove the center box)
