Yeah they are nice ,

Um any ideas on the exhaust cheers

GARETH T

and you cant get in the mens room as i posted all my faith links

havent a clue,, i dont know what type of ECU they have,, is it map based or air flow meter?

motherhupit

don't know its a citroen vtr probelly a air flow meter, but not sure

Knowing the piss poor nature of PowerFlow exhausts it probably has less power than with the standard one

motherhupit

thats what i thought the exhaust cost him £250, i know that puma racing done an independant test on after market exhaust and only one out of ten showed a improvent over a new standard items, for my car i just bought a brand new standard center section and then just removed the back box seems to work pretty well sounds nice aswell, sounds like a full system.

Very little difference i would expect, unless its a particuarly badly made one (powerflow vary a lot) in which case it may have lost quite a lot, but it certainly wont have gained anything significant.

motherhupit

so where talking what 3hp at the most

motherhupit

i don't know the actual make i'll have to ask him

Only way to put a figure on it is a dyno comparison against a standard one.

But i bet he would have got more power by lapping his valves in if its done many miles!
(ie i still doubt it makes standard power now even if its a good exhaust)

motherhupit

nah its a pretty newish car say 30k max

Well if he really wants to know an exact figure, tell him to take it out and strap it to an accurate dyno, anything else is guesswork really, in terms of to the nearest bhp or two anyway.

Im sure its louder now though, which is no doubt what really interests him!

motherhupit

Cheers guys for ur help, i'll just tell him 2Hp to be sure, don't think he'll be getting it dyno'ed for a while.

Yeah 2Hp loss through most of the rev range sounds like a respectable guess mate.

Cat-back is PANTS. The filthy horrible old "Cat" is probably the most restrictive bit anyway.

Anyway, maybe www.passioncitroen.com would be a better place to ask?

motherhupit

Yeah i agree if ur gonna spend 250 on a exhaust why don't u do it propelly, cat can take away as much as 10%, he recons he's getting 5HP more, i'll tell him other wise, didn't know there was a place called passion citroen anyway i ain't that bothered just wanted to know cheers guys.
