Not yet mate, don't think I'll be able to put the purchase off much longer though, I'm reaching the limits of the car without one.

you can certainly say without one it is preventing you taking it further forward at present , and you are probably not getting the full benefit of the other mods u already have.
- next on the list

But you could be reaching the limits of your wife's goodwill if you buy one.

Respectfully I would disagree with you on the effect of a well designed and built d'pipe with good quality cat. We are talking in the context of earlier cars here and as I stated in my earlier post a decent cat/d'pipe combination will add 8bhp or so, a cat back 5bhp....or thereabouts.

Regards, Don.

Fair enough Don, 'much' is a relative term. After speaking to Jan Woth about his Priscilla project the opinion I came away with was that a cat back was a 'must' to go with a remap.....only about 257 bhp max without a cat back and 270 hp with.........and a downpipe/cat would not give much more.

I checked this out with TME, they thought that a software update and a full system would get my car up to 280 to 285 hp and 420 Nm plus improved response. That difference is in the region of the 13 hp you mentioned.

It depends on how much you want to spend for that 10 - 15 hp I guess.

Right, I have made my decision on who I'll be getting my exhaust/downpipe from, one question though, I can either have a 2.5" downpipe or a 3" one.....what are the pro's/con's of each please.

[M-R-P]

one's cheaper

[V70 Graham]

one's cheaper

Our survey says.....Errrr errrrr, nope smart bottom, I can have either same price.

LeeT5 used them at the beginning of the year and highly rates them, Sarkey San (Sharkey R) has also had work done there and was very pleased.

cant wait to see it. plenty pics of it on the ramps

yes graham, to remove a cat completely on a car after 1993 is a direct mot fail. one must be physically present to pass (race or otherwise)

Is this relevant for diesels also? As i'm planning to do a 2.5" stainless straight through system on mine soon

diesels dont need a cat to pass mot. diesel have a smoke test and not emision test.

Because I think you'll hate the extra noise a 3" makes I'd advise going for the 2.5". The gains you'll loose out from not getting the 3" won't be noticeable at your stage of tune.

or 2.75 (as per miltec).

That's exactly what I was wondering Andy, as you know I'm not after a mega loud system.

[t5 pete]

Tbh I didn't notice any noise increase on my 3"down pipe compared to the standard one it replaced

Powerspeed is local to me and I know plenty of people who have used them. I've never heard a bad word said and the work I've seen has been of very high quality.

3" every time. they adjust the silencer sizes to suite. i had remove one of my silencers as it was quieter than standard.
