Hi,

 

Need some advice on the removing a cat from my car. A firm in walsall has quoted £80 for a replacement with a high quality S-steel replacement.

Can anyone advise on the following questions i have

 

1. Would my car stilll pass with a single cat? My car is a UK TT

2. Which cat is it best to remove (1st or 2nd??)

3. Any drawbacks of removing the cat?

4. What kind of power gains can i expect?

 

Any comments would be much appreciated

what about removing the 1st cat instead of the 2nd cat as the first is closer the manifold? Would this make a differerence?

 

Whats a EGT??

 

1) It should do. Replace Decat #2 with cat #2

2) Both.

3) Higher EGTs - I think.

4) A fully decatted UK car - expect to see 0.9 to 1 bar boost. You'll need a boost controller to raise it to 1.2Bar

 

Search for BPU.
