Title: How do I tell what exhaust I have?
Post by: Karl_mac_ on March 10, 2014, 01:24:28 pm

When I bought my car it had an exhaust already fitted, i've been told its a blueflame cat back, which to be honest I thought sounded pretty loud for just a cat back.

At the weekend I went out with a mate in his Focus ST fitted with 3" decat and a Mongoose 'Section 59' exhaust, so called because its effing loud. When we parked up a few people commented that at full chat mine was much louder than his and were convinced mine must be de-catted.

I've got the MOT in april, is there anyway I can quickly check for a decat pipe/downpipe.

I've looked down the back of the engine (from the top) and it all looks pretty much brand new down there, but haven't got a standard car to compare it against.

If it's standard it will have 2 cats,one where the downpipe joins the manifold and another at the end of downpipe near the middle of car. Aftermarket downpipe will have one cat
