Hey guys, I'm looking to get a de-cat for my car to free things up a bit
I was wondering if anyone knew any places that could do it for a decent price?
In or around Coventry would be best :)

Cheers folks :)

id have to dissagree with you about them being good. Ive had good service from them years ago but more recently they seem a bit shit. Think Han will agree with me on this one.


If it dont scuff the ruff, it aint low enuff

I found Crackley garage (powerflow dealer) really helpful when I had my exhaust altered, could just try giving them a ring to see what they're like price wise

As far as i know mate ul need a remap to get the best out of a decat. Thats just what ive heaed tho so guess it could be different for turbo and n/a cars

It varies from car to car, but the general notion I get from decats is more noise, alittle bit of power gain, but little bit of torque loss

After Han had a decat his car was dyno'd and didnt gain anything in BHP, no word on torque
Not helped that our ECUs cant be touched

At Crackley for a silencer to be removed and the rear tip extended I paid £86, Im guessing decat would be the same amount of work as removing the silencer... so hard to judge it!

MIJ quoted me £90 for a decat pipe but i think that is just a bit of pipe to replace the cat.

A decat will only make a small difference in bhp/torque to a turbo'd engine & allow the turbo to spool up quick & help the the engine to run freely so more for fine tuning but you would lose power on a non turbo'd as they need backpressure & would need a remap to get it working nice agian.

Im getting my cat for xmas as nexted year its uprated IC, Hybird turbo & a custom map to finish it all off.

Keep the pipe smaller from the manifold to the decat pipe to keep the back pressure :)
