2.25" from cat back. When will this become restrictive?
Really need some advice on this lads and got **** all in my other thread so here's hoping.
Current inherited set-up.
Standard up and down pipe and centre section with all the cats in place.
Non-standard manifold (I think it's equal length due to the exhaust note, but a local mechanic said it wasn't)
http://bbs.scoobynet.co.uk/showthread.php?t=452490
and a Fujitsubo TI cat-back 2.25.
I'm going to replace the up-pipe, decat the down pipe and fit a high flow centre cat. I don't want to do this and find that the bore is restrictive when I look at the TDO5 a bit later.

It's not clear what you want to know!
Your headers are unequal and a 2.5in exhaust will handle anything a TD05 can blow at it.

I'm going to have to get it up on the ramps and get the vernier out because I had a look at it today and the pipe entering the rear box is definately bigger then 2.25. It was checked by a mate at Longlife a few days back - he put a 2.5" tube in the box (past the tail pipe) and no fit - 2.25 nice and snug. I wonder if it tapers in at the end (it's a very quiet system). Fujitsubo Super TI

Hello,
When I was running a fujitsubo legalis R cat back on my 98 car the pipework was 2.25" at the downpipe to centre joint, this opened up to 3" bore further towards the back with a silencer in the middle. Nice quiet system but huge tailpipe. Car was making 350 power and 325 torque

So you had a (centre) catback sytem? In what way was the Legalis connected to the down pipe??
Was it not turbo back?

Have had various combinations of exhaust system.
Had the fujitsubo fitted with h+s open neck dp 3" to 2.5" then it went to 2.25 where it joined the fujitsubo cat back system and after the downpipe joint out to 3" bore pipework there was another smaller section inside the backbox but it didn't seem to affect it
