Anybody got a 3" downpipe from Longlife?

[Rusty]

For comparisson the Milltek system is about £1000 - £1200 for 2.75" turbo back with sports cat. The cat is about £200 from memory but don't quote me on that.

I've heard varying reports about Longlife in South Gloucestershire and seen different levels of success when they've done friends' exhausts. They messed up a friend's Cosworth and did the same trick you described at the beginning of the thread. For that reason I did not go to them when I got my exhaust in November. Cardiff are supposed to be much better but that's hearsay and not experience I'm afraid.

cardiff is where they started out with Longlife and the guy who did my original system was a craftsman. I then had it reworked (for free) at Carlshalton and again no issues. It was their 2nd site and I think half of the Cardiff people were there setting up the franchise. Personally i think that is the issue, they are franchises and the quality seems to vary be it prices, workmanship and even customer service.

Spoke to Leeds and don't feel that much further forward.

The boss said they didn't do the downpipe cos they couldn't get it out without taking the turbo off and they would not do that. He also said that the turbo end of the downpipe is a casting and they wouldn't replace that with tube anyway.

I told him that at least two of you have had 3" turbo back done at Berkeley and he says he hasn't been able to get through to them to confirm but if I can get registration numbers of the cars he would be able to check up what had been done on his computer system. So CHEN and Ross (and anyone else who has a Longlife 3" turbo back system), would you mind PMing me your registration numbers so that I can do this.

As a last comment, the boss said that if I could get my downpipe to him when my turbo is off he would try and make a 3" downpipe for me to take back and fit to the car as it is reassembled. Although I have reservations about doing this in case the bigger tube fouls on part of the engine/body etc I think it'd be best to try with another downpipe so that I've got the new one ready to hand to the guy that's fitting my new turbo. So, does anybody have a secondhand ABY (or RS2) downpipe kicking around that I could either buy or borrow? Even better would be if someone has a 3" downpipe that I could borrow for them to use as a pattern.

Just phoned Quattronics and asked what size the outlet on my new hybrid 2871 turbo is. It's 57mm (approx 2.25 inches) diameter so the question is, do I really need 3" exhaust tube at the turbo flange?

As I understand it the S2 downpipe is 2.5 inches (and the RS2 one is 2.75 inches) so am I correct in saying that there is already room for the exhaust gasses to expand into even with the standard downpipe?

Would a transistion from the 2.25" turbo outlet through the 2.5" cast part of the S2 downpipe then into a 3" pipe give a better flow for the exhaust gases than just dumping them straight from the 2.25" turbo into a 3" pipe?

Here are a few photos of the new exhaust

I have an RS2 downpipe that you can borrow.
If they damage it they pay for a new one.

Thanks for the offer BRY

Having thought about it a bit more I think the best route is to buy a cheap S2 or RS2 downpipe and let them modify it by grafting on the 3" stainless pipe to the cast section. If I borrowed your downpipe I'd worry that they'd want to modify it rather than fabricate a new turbo flange.

I'll put a wanted ad in the classified section.

What happened with this in the end? which branch was the downpipe sent to?

[K7ERG]

I got one made. But it was a mate who done it. I kept the original cast bit and where the original pipe is. Cut it there and 3" from there back. Mandrel 3" bends.

Want a true 3 inch downpipe from tip to tale. Most I've seen have a 2.5 to 3" taper at the start but with a Garrett turbo the outlet is 3"

[K7ERG]

Yep 3" all the way back from the cast part with lambda sensor. They never had dies for 3" at the time so had it made from 3" pipe and bends.

The cast part is a 2.5 taper on the oem manifold as the KKK turbo outlet is 2.5 inch not 3 inch like a GT-R turbo
