HI.
Just looking for a quick answer on this please, I have a full bcs exhaust system including a sports cat on my mk1 rs, ive been thinking about fitting a decat for a bit more noise and a few more cracks out of the back. Would it be worth the change or will there be little diffrence? Thanks paul.
I have a sports cat on my mk1 FRS and am happy with that. It is a blue flame one so exactly the same as BCS as Nige from blue flame went to BCS a few years ago now. If you are a number cruncher then you won't get as high gains as a decat will give you, from a sports cat and the sport cat is noisy but again not as loud as a decat. It's swings and roundabouts to be honest. I opted for the sport cat route as the area where I live do a lot of VOSA spot checks so didn't really want the hassle every time I drive to the gym. Now the mk1 is in storage though.
When speaking to demon pete when there the other week he suggested I go for a BCS sports cat as opposed to decat.
No MOT's over here to worry about but he said if you've got the car on trickle charge it'll run like **** for a while everytime you take it out for a drive with a decat as it'll have to relearn everything.
Remember Nige saying that the sports cat is so unrestrictive that there is no noticeable difference between it and their decat
I couldnt tell you mate, I haven't been under the car since I bought it, all I can say its bearable when driving it steady without any drone but once you give it some beef it barks out a lovley tone without been to chavvy. its a perfect balance really, a quality exhaust.
I had some unknown brand decat pipe on with my BCS single box on the last car and it did sound good. Just worried the sports cat might make it too quiet lol
i would say yes about the sports cat making your exhaust more quiet its like adding another box
to your system so to speak
