powerflow tomorow

[Mikey]

my cars going for its powerflow tomoz, just cant decided on tip design. i was thinking a nice oval or boxer tailpipe. help please people

[Barry123]

nothing too phat.

inwardly rolled, single suits the paxo. go knows on diameter, but dont go for a dustbin diameter.

ye i dont want a drain pipe, just sommet subtle and sounds good

[Curran]

i think this looks best, either single or dual

3653

what size is that pal??

[Curran]

not sure, either 3" or 4". someone on here will be able to tell you

its a guy's car who's a member on here caller "carln" if you pm him he'll be able to tell you. i think he's sold the car now though and i dont think he's on here very often.

[Baz]

looks about 4"

IMO 3 or 3 1/2" inward or outward rolled does the trick

[saxyVTRsaxo]

Thats mine with i think about a 3" tip

I recall DampCavid saying that 2.5" was the best for performance.

[DevilDamo]

Ads... Are you talking about actual pipe diameter? If not, I can't see how the size of the tailpipe has any effect on a cars performance :-S

[Curran]

surely the size of the tailpipe cant effect performance greatly. i think its more to do with the size full exhaust system, such as the size of the centre section. maybe thats what campdavid meant by the best size being 2.5"? if you know what i mean.

damn it, damo you beat me to it. i need to type faster!

[lwalker]

2 3inch pipes to the left.keep it simple but more exciting then single

[lwalker]

jus like the pic up above but another 1 next to it

might have been the full system diameter :oops:

Actually the exit nozzle does have an effect due to exit pressures and subsonic/supersnoic flows and all that sheeeeiite.

I recall DampCavid saying that 2.5" was the best for performance.

he would have been on about bore of system, and i think it would have been 2.25 not 2.5, thats too big for NA. tailpipe doesnt afffect power. also, powerflow exhaust will do nothing for power, it will probably be worse than standard.

[rushy_23]

Idea bore for highly tuned 16v engines is 2.25" yes. (tailpipe size is irrelevent) SP
No point on a next to standard car from what Ive read.

If I was you mate just go for a single 3.5" inward rolled (like the magnex)
It may not look anything special (or stupid imo) but its definatly the best
looking tailpipe for the Saxo.
Its nice but not over the top if you know what I mean.

[Dan]

Yeah I wouldnt go to powerflow for a performance exhaust. But if you have decided on it I would go for something similar to the shape of a btb personally.

there's no way thats a 3 inch diameter tip, no wonder kids these days think they have big dicks! half of them don't know what an inch looks like! :panic:

[rushy_23]

Nah I think that is 3" Oli!

You better get your ruler out again cus I think your telling your missus porkies!

LMBO!!

Does look like a 3", if not its 2.5".

[williamsvts]

pwoerflowsystems have a smaller bore than the standard system!!!! when yu couple that with non-mandrel bends its even worse. it will be about 1.75" on teh bends!!!!!

[rushy_23]

I heard its still 2" ?
Must be wrong.

There is a custom place by me (MIJ Performance) and I think all bores are
set to a default of 2" unless stated otherwise.

mines a 2" bore and its powerflow and i didn't ask for it! thats just what they fitted for me!

[williamsvts]

i measured mine and the OD was 2", so say its 1mm thick piping its gunna be 2mm under 2", then there is the bends where it reduces.

[williamsvts]

have you measured it with a vernier or micrometer?

[S34MER]

I remember asking the guy who fitted it, a lad called Paul who i know there and he told me the piping he's using is a 2" diameter bore! now surely by bore he means the inside of the pipe not the actaul pipe thickness aswell!

[williamsvts]

bore is the inside. measure it though, it wont be a 2" bore.

[Barry123]

tailpipe doesnt afffect power

naaa as long as there is a device connected to the exhaust system then it'll affect it. Until the gases are out into the atmosphere then whatever is in the way of the exhaust gases will affect how the engine behaves.

too big - very little back pressure, results in bot all torque at the bottom end.

[S34MER]

bore is the inside. measure it though, it wont be a 2" bore.

yeah! so im gonna cut a chunk outta my system to see if its actually 2" bore!! not likely ;)

[williamsvts]

you could measure it where it connects to cat. or measure OD, that will be 2".

ad - its the 1st silencer that affects power, tailpipe does not. check the size tailpipe on WRC cars.

[Ryan]

powerflow ive only ever seen shite from.
wouldnt touch em with a 40ft barge pole myself

[williamsvts]

from my experiance the build quaity is good. just not designed for power. had 2 in the past.

ive seen a couple of stainless steel ones, where they have not lasted atall, wleds have been shoddy...

and deffo what you said, no good for power.

[williamsvts]

i got my 1st 1 nearly 5 years ago. the car has donje 90k since thenand its still on with no probs.

[Ryan]

it must depend on the dealer then...

the ones ive seen have been far from great though

i think you'll find that it is a 3" tip, ta very much.

[Ryan]

lol take a pic with a tape measure just to prove so :P

[lavo-vts]

my powerflow system is 50mm bore its excellent been on the car 4yrs now and is still like new. also got a magnex de cat pipe which is 50mm bore

[williamsvts]

have you measured the bore with a vernier? they are 50mm OD.

[lavo-vts]

have you measured the bore with a vernier? they are 50mm OD.

50mm is the bore as the od is 53mm by the way 2" is 50.8mm
