Title: Can anyone advise regarding a BCS catback exhaust.
Post by: Ramsay on August 11, 2013, 12:55:59 pm
Hi I bought a BCS Powervalve catback exhaust from a member on here however I dont think its going to be a straight forward fit and was looking for a little advice.

The origional exhaust has no seperation after the cat, it goes from the cat straight to the turbo so I'm guessing that if I wanted to fit the BCS I would either have to buy the Downpipe or chop my exhaust is this correct?  The diameter of the standard exaust also looks alot smaller than the diameter of the BCS.

If so how easy would it be to get someone to chop and fit the catback ?

Here are some pics

I'm thinking I could use a grinder to cut the standard exhaust before the sensor then pop on a step up pipe then for the bcs?  Is that the best way to do this ?

Thanks :D

I had contacted BCS who were more than helpful.

For people who come across this, the powerflow exhaust is not recommended for fitting as a catback system (BCS only supply it as part of a turboback system)  as the sound reduction from the standard downpipe restricts the sound produced from the powervalve therefore rendering it almost pointless.

I have been told that installing this exhaust as a cat back system will not damage the exhaust or car and requires a reducer pipe which BCS are going to supply for me.

I will thereafter have to cut my standard system after the cat and install from there should be straight forward (hopefully) lol.

Lol  just can't be bothered swapping the exhaust out for MOT time or I would lol

Been quoted around £40 plus vat fitted as well or I can spend a few hours fitting it myself lol don't know if I can be bothered though
