cup de-cat

[yeecup]

is there a de cat available yet for the cup? not interested in ktechs racing cat, £200+ when a straight pipe would be better and a lot cheaper. any ideas of gains, (if any) also will it make the magnex cat back system a bit louder?

Dunno, but I aint seen one yet...

Well, depends.......

if youve got a k-tec exhaust with the telescopic section, then you can use their mk1 172 decat and disconnect the second Lambda sensor - it works well

but you cant do this if you havent got an exhaust with the telescopic section as the mk1 decat is about 2 inches shorter than the mk2 cat you are replacing.

Yeah its called a Supersprint 63mm Race system.

Straight Pipe from the downpipe 2 a small box at the back. No Cat, No silencer. No Problem

Devil do a de-cat pipe for the mk1 which will work with a mk2. A decat alone will (in my experience) improve your bhp and torque mid-range, but with the stnadard exhaust, wont do much to improve your peak power. Install a mk1 decat pipe and then do as Roamer says and disconnect the second sensor.

Or, if you can bear the noise, the Supersprint!

Chris n nic, removed the cat and cut the business bit out the middle and welded in a section of tube.

One of the welders at work says he could do it no problem.....Just abit worried about any warranty issues.

what does a lambda actually do? and why do we have two?

Really...

And this will fit into a standard exhaust system with no alteration?!

I want a direct replacement, no @rsing about!

Measures the exhuast gasses, then the ECU decides what to do with the engine setup. Most modern cars now have 2 of them...
