Downpipes from Longlife

[S2 Ant]

Im also in need of a system as well, it will tie me to changing to the RS2 EM only but i dnt think i'll ever go beyond its max HP anyway.

Keep us up to date please.
Thanks

There is a Longlife in Leeds 0113 279 8944

And if you mention s246parts we have a discount set up with them

[madS2]

no probs mate when you planning on yours?

These downpipes - are they designed for the two pipe split or do they just stay as a single 3" pipe? I'm sort of looking for a downpipe that splits into two 2.5" pipes where the cats used to be.

I'm sure if you went for a fitting Longlife would do whatever you wanted to make the downpipe fit...

Don't you have a 3B Keeper? Personally I'd get them to take out the whole 2-piece section and put in a single pipe; between the 'cat-back' and downpipe. They did that with mine as aparrently that big heavy de-cat section woulda been a huge restriction, and also makes the job easier for them too to just replace that section - so they won't charge you an arm and a leg for it either.

Yes I do Ross, Kitty is 3B and proud of it!

Hmmm...

Well the way I saw it was that 2 x 2.5" pipes are a bigger cross section than 1 x 3" - and that matters more than tuning the pipes in a turbo motor, yes?

I also want (or perhaps wanted, past tense!) to run pipes under the diff to the tail, so even an extra 0.5" might be handy clearance. Maybe, maybe not!

Or perhaps I should bite the bullet and have a side exit system?

There is a very competent fabricator of exhaust systems and other stuff in Attleborough, Norfolk, who makes bits for bikes and cars and most other things too I guess, I have heard only good things about him (and his prices are very good). Will be enquiring with him soon to see what he can offer.

I am beginning to like the sound of these Longlife people though!

Martin , Cr500dom told me about a place in Attleborough , he said the guy is a pro when it comes to fabication work i was going to contact him about a 3'' downpipe :mischeif:

[Ross]

I think (but am no expert!) that it would be favourable to keep the gases flowing straight and consistently down a single pipe, rather than splitting the flow and running it through bends, which is gonna slow it down. The extra bore might negate this effect, but it'll still weigh more. Plus, the old piece was flattened on the top partially - probably making it more like an effective 1.5" bore...

This is assuming you still have a stock system of course. Or are you talking about using twin pipes all the way back from the base of the downpip?

No updates today by the way, I left my mobie at work and spent the afternoon in traffic queues in Reading. 16mpg - I think most of the energy was expended to keep me warm for the hour and a half it took to travel a total of 15 miles...

but with all the bends, y pipes, ect you will get slower gas speeds then with a straght 3" pipe

[Jon441cc]

I dont think ss 3'' downpipe would be that much noiser then stock.

@ jon
I'll try to take some pics for you tomorow.

[robo]

I got from work 6 o clock it was to dark, I'll try tomorow.

@Jon441cc - that's the chap! It's ok I knew about him anyway, many folk at work have made use of his services before. BTW the place is Bunns Bank!

@Ross and Pete - my intention is a dual system all the way to the tail, with two silencers, one on each pipe, close to the end (the most efficient way, better than silencing further up the system).

As there are already bends at the area where the downpipe goes under the car, I saw very little advantage in using one bigger bend in the system than two smaller bends (but it would be feasible to use slightly larger tube for smoother transition on both tubes).

However I was seeking a cleaner exit path by not routing the pipes over the rear suspension, and not having a transverse silencer at the tail - everything behind the split into two pipes would be virtually straight, maybe rising a little in the middle area for clearance and dipping below the diff, but essentially a straight shot from the moment the pipes turn to face rearwards on each side of the gearbox.

Well, that was my theory anyway!

BTW Kurrent Kitty system isn't stock, it's the ubiquitous Scorpion (I think it's Ø2.75")

Paravanni is the guy I was thinking of using for downpipe and system.

In terms of extra bends and Y pipes - well, there is only one Y piece and one extra bend (two at a push), which I am sure would be negated by the extra total cross section, easily. The weight is the other issue which concerns me, would be willing to "risk" a reduced wall thickness to help negate that (and the dual silencers would feasibly be lighter than the mighty transverse piece!)

Damn, sounds awesome

A genuine twin exhaust would be pretty wicked... a straight pipe too? I'm sure if it's all custom then it'll be designed by someone who knows what's up (or at least you'd hope )

Plus, wouldn't that make it a little quieter having 2 smaller bore pipes?

Anyone gonna take the plunge and see what paravanni could do in the way of downpipes? If Longlife don't deliver, I'd make a trip up to Norwich if the price was right!

Nothing wrong with having a couple of different options eh?
