ABY de-cat pipes

[JamesHarrold]

Dont really know what everyones opinion is, but was going to get rid of the cats on my aby coupe....Question is....is it worth doing and has anybody got a couple they want to part with?
On the same subject, I am really hoping it doesn't increase exhaust noise too much....I f***ing HATE chavvy sounding cars!

Any help would be greatly appreciated as always gents

Cheers

James,

I tried it using a set of decat pipes I bought. Didn't notice any increase in noise but also didn't notice any increase in anything else and put the cats back on for good before the next MOT.

So, yes I have a set of ABY decat pipes available but being honest can't see that it's worth it on a normal car.

Thanks for the info John...

I am sure I read on here that someone found a little increase in BHP and torque and that spool up was slightly earlier...Not that I am expecting miracles by getting rid of the cats...just nice to know!

Still not decided, but If I do go for it I will let you know...How much are you asking for them?

Cheers

totally opposite experience with mine, definately increased the noise and also made the car feel much crisper on the throttle and liberated a few ponies too I think. Seat of the pants suggests so, r/road will verify soon enough i hope...

As my cats are now bolted up with stainless steel bolts, it wouldn't be too difficult to do a before and after at Dest's rolling road session in September using my car as the guinea pig if people are interested?

The same as David, I hate my CATS they make the car slower, quieter and less fun to drive.

Remember: You will need them every year at MOT time. (Only putting them on once a year is a good way to save them too.. )

Cheers,

Sports cat is the best option on an ABY, saves messing about @ MOT time. My car ran well with the cats on and is a tad better with the single box and sports cat, guess it's a matter of suck it and see. Any custom exhasut place should be able to sort you out with decats for £100 or so.

Mine got a LOT louder when i took the cats off, but that was with a straight through system, no centre box and just a Milltek rear box.
Definitly made it pull better though

[JamesHarrold]

Thanks for all the comments guys...
Will be running a standard exhaust. The cats are non Audi, so I am guessing not quite as free flowing anyway. The car is homefried which again hopefully suggests that removing the cats will aid breathing slighly.

Have decided I am going to give it a try anyway. As you say Steve, they are fairly easy to replace and can put them back on when MOT time comes round.

Just need to find a pair of bypass pipes now...Do you want to sell yours John? (johne)

Seriously, you will love it! (It doesn't sound chavvy at all, just more meaty and powerful sounding! )

[JamesHarrold]

Thanks Steve....

Just need to find a pair now...

PM me your e-mail address, I know a bloke who has a set available


and yes, i support the positive effects of having decat pipes instead of cats, much improved spoolup under real road conditions, and a bit better noise.
