Will I benefit?? Are there any issues??

Round

Hello all,

I fancy removing the pre-cat (free mod) but I can't afford to buy a replacement air filter or vectra c pipes at the mo.
So, will I still see a benefit?
Has anybody had any probs after they have removed theirs? Funny idling/running?
Will I encounter any probs if I don't upgrade the air filter etc?
Should I just wait until i can afford the others.

The thing is cats are expensive and I don't want to have to buy a new one because I have ruined the running of my car.

Cheers ppl

I am sure some one will confirm but from my understanding there should be no issues if you dont ugrade the air intake or filter. You will not see much increase but you will hopefully get some of the flat spots removed by doing this mod.

I have only heard poeple having issues with EML light coming on if they have moved the sensor. I myself havenot got a pre-cat in mine or done this but hope my info has helped.
