It's a piece of p1ss and should take roughly an hour if the bolts aren't seized and don't snap, the up-pipe is the tricky one. Just make sure you get some proper penetrating oil on the job the day before to give it plenty of time to work and spray it a few times with a few hours gap in between, a tickle with a wire brush before is also a good idea.

Thanks ditch mate I'm just about to buy a 3 inch decat downpipe will it fit to my centre section because I'm not sure what bore that is, the bloke selling it to me says it will fit wether my exhaust is 2.5 or 3 inch????? As it was fitted from to a 2.5 centre section on his? Is this true

I don't know mate it depends what pipe it is as some of them are tapered to 2.5 which is the type I would be wanting to fit, get him to measure it inside both ends, also some of the 3" pipes are not "true" 3" so you need to do a bit of research and find out before you get your cash out and start crawling under the car.

Just got the car it's a bug sti trouble is I don't have a clue what brand exhaust is fitted or the what brand the decat for sale is "?????? Hassle lol I'm not even sure if my centre section is2.5 or 3 inch ., is there any way to measure it without taking it off the car? Do u measure from inside to inside or the whole pipe"????

Cost me £285 for mine fitting for nearly 6 hours labour. I was at the respected tuners 10 hours waiting.
