Anyone fitted a de-cat pipe ???

Hi sorry as i'm sure loads of people have asked this, but i wanted peoples view on a de-cat pipe and if they lost any torque at all and if it does make the car any faster ???

Thanks

I have one fitted to mine - cant say I noticed an amazing difference but it felt a bit more responsive and sounded better & on the rollers I got 214bhp from a de-cat, exhaust, filter & more than likely a chip of some sort but I havent fitted one or looked at the ECU yet. You'll need to put your cat back on for MOT time unless you have a friendly MOT tester

Thanks for that its nice to get ideas from others of what works and whats doesn't, otherwise it gets expensive.

Thanks mate

If you have a charger its well worth it... getting rid of the cat and centre boxes unleashed about 15bhp and 20lb/ft torque on mine and made it a lot smoother to drive

One of the reasons i've asked this is because on my last vr6 i had a supersprint cat back exhaust but without the centre box and it seemed to lose torque on the bottom end but freed up the revs at the top end. And thats what i dont want to lose the torque it was only slight but i did notice it.

You will lose torque if you reduce back pressure in normally aspirated applications. I have a supersprint cat bypass on mine and it made a profound difference in N/A and with the charger. Much keener and smoother. I have retained the factory Lientz Corrado system because it's f'in brilliant basically. Lasts 10 years easily and flows very well....and more importantly, it's quiet.

With chargers you can get away with a relatively restrictive system as unlike turbos, excessive back pressure doesn't stall the turbine.

I was just reading your thread 13 mpg, The charger sounds spot on i would like to go down that route within the next year, Whats the average cost of a fairly cheap but decent charger kit ??

MikeG3 - see the group buy section, theres a group but at the mo for charger kits but if you want to wait til next year get the details of Ultimatetune from the thread ;0)
