Decat question
I've just got myself a standard STI spec d and was wondering if I can remove the 2nd cat pipe (after the downpipe), centre resonator and change the back box without it causing any running issues or engine lights coming up?
All advice welcome Matt |
I think the hawkeyes can be a bit funny with you if you remove any of the Cats and not map it afterwards.
What backbox you sticking on? |

:facepalm: you do know that the D in Spec-D stands for discrete don't you? so its meant to look like a WRX but it's an STI underneath, great if you want a sleeper car. Stick on either of those exhausts and you might as well have just bought a normal STI.
If you want more noise change to a De-resonated center pipe but go for a RaceBox exhaust so it maintains the standard look. Remove any of the Cats and you'll need a re-map. |

The lack of burble is due to equal length headers, not the exhaust or the cats.

Yea stay away from those equal lenght exhaust manifolds, they take away your burble.

Look at Scoobyworld's catback offerings ... I had the Racebox catback system to my bugeye and it gave off the lovely burble without being overly loud or enough to annoy my neighbours. Suffice to say I will be having this fitted to my Hawkeye when they have the racebox back in stock.

You will not get the burble as you will have equal length headers, am I speaking a foreign language? |

They will never be a sleeper as such, still always get people wanting to take you on.:lol1: |

I bought mine because I wasn't a great fan of the ghastly interior in the STi.
