Prospeed Exhausts - Cardiff - 2011 Update

[MikeLarwood]

Will be asking them if they can do 2xS2s at the same time on that day I think - I'm looking for the **** end to be done at the moment as it's in a bit of a sorry state!

[Rusty]

If it's a cat-back then I think you'll be OK but a turbo back is a fairly large ndertaking!

Mike, I'll have the DP and cats for sale if you still need them?

[MikeLarwood]

Nah tis just a cat-back! I've got my two de-cats coming before then hopefully - assuming the Germans pull their fingers out! But I'll have a look over your cats and if they're any good I'll have to let you know!

[MikeLarwood]

Booked in for Saturday... Will see you there chap!

[Rusty]

You'll see my car but not me I'm afraid, it's being taken there by a mate of mine called Si, I'm not too well at the mo so he's sorting it out for me Nice of him eh!

Just resurrecting an old thread.

Have been back to Prospeed (at their new shop in Cardiff) and had my DP modified, as well as a few other things added to the exhaust I was made more than welcome, despite my car probrably sending shivers down the owner's spine and we got a lot done over the day.

I've now had the DP V banded, to make things easier for future removal and also had a large flexi joint welded in. I also now have 3 lambada bosses in the DP - 1 at the turbo exit for my EGT probe and then one a little further down, followed by 1 on the downward section - this will enable me to run a wide and narrow band lambda, in addition to the EGT, if I want to!

I was also chatting about getting some more noise out of the car and it turns out that Prospeed now offer exhaust butterfly valves :mischeif: They have electronically actuated ones that can be opened by any amount and they look to be very sturdy I was quoted £250 to have the valve added to my system with a Y pipe and a 3" side exit, straight through pipe! All in all, this would be a very nice addition, so I'll get saving. Also means that I have the lovely quiet system retained for longer journeys. This carries on from this thread. The chap I was helping take the car apart, kept telling em to get a screamer pipe on there... as did the two girls in a white 206CC I think I'll pass on that one for now.

The exhaust system still looks to be in excellent order and is as solidly mounted as it was 3 years ago - I'm still happy with it.

When I was there, Charlie was telling me about a Capri Perana that they'd done - here's a video - http://vimeo.com/19795649

This is the product that is used - http://www.dmhperformance.com/index.html

Here are some long-awaited pictures of the DP and a couple of extras (excuse the quality, it was poor light and on my phone).

The top section is 2.5" and then 3" from there onwards - not ideal but there we go.

[Error404]

how come they didn't just use a cone out of the flange straight into 3 inch mate?

[Rusty]

No idea - I'd guess space and the small OE turbo outlet - I wasn't well enough to get there when they were making it

[Rusty]

So got the emissions checked today prior to the MOT and the CO just wouldn't drop below 0.47% so looks like the cat is screwed (lambda is cockon). Booked it in for a replacement cat and have opted for a 200 cpi option so I can fit and forget. Various options are available but I don't want to mess with swapping pipes or have the yearly long-idle test countdown at the MOT, as the cat warms up bit annoyed at having to shell out for a cat again so soon but the new one is being offered at a significant discount to sweeten the deal. Shame I don't have the extra cash for the cutout valve at the same time...

Andy,

How much is the average price for a sports cat when fitting a 3” inch downpipe and exhaust to an ABY ?

What is the cut out valve you are referring to ?

Thanks.

My extra half inch.

I had a full 2.5" turbo back built by prospeed before, but since i had the car off the road the tempation of the Nuvo 3" downpipe was to great!
I sold my 2.5" DP and cut out the middle section and fitted the Nuve GB DP (really nice piece)

I took it down to charlie on saturday who was pleased to see me and have a chat.
He set about continuing 3" stainless from the base of the DP back to just before the rear subframe (where the old 2.5" prospeed system continues.) Every effort was made to ensure it didn't dangle too low.
I did want a flexi section added, as per the previous pro-speed 2.5" section, but charlie assured me it wasn't required as the the engine and subframes are mounted very rigidly with solid or track density mounts. (At the end of the day, the system has a warranty, so what charlie says is good enough for me.)

Some pics
Pic1- Shows the new section from the front of the car

Pic2- Shows the end of the new middle section mated to the 2.5" rear section, unfortunately the ground clamp is hiding the small 3-2.5 conical transition into the flange.

Pic3- Close up of the front section, inc Mikalor low-pro clamp and extra mounting to GearBox.

Pic4- Extra mount on rear section to the subframe (helps stop the exhaust hitting the body or CV where it goes over the back)

Pic5- Pic of Pro-speed 2.5" Backbox

The flexi is not generally to save the exhaust it protects the turbo/exhaust manifold from undue stress when the engine moves. Im pretty sure this is why S2/RS2 manifolds are cracked as the stock setup allows very little movement. With all new/stiff engine mounts it should be fine though! Sorted your oil leak?

[re2500]

The extra mount to the gearbox should help reduce stress on the turbo/manifold. Oil leak not sorted yet, got a couple of people getting back to me about coolers.
