Pro speed stainless steel exhaust

[anthonys2]

Hi guys as the title suggests am curious about the above company and wondering if anyone has had any dealings with them? At the moment i have a miltek back box down to the middle and i now feel its the right time to make it all stainless steel.

What I have been told is available is a 3" downpipe and a 100 cpsi high flow sports cat(double dutch to me!!) and its made out of T304 stainless steel.

I know the question has been probably asked a million times but some help and advice would be great please and very much appreciated also what about MIJ performance

Thanks guys

One of our local aftermarket exhaust makers has stopped selling the 100 cell 'sports' catalyst in favour of a 200 cell as they were having problems with people not getting through the mot easily.
Admittedly they were very cheap so the problem could have been down to the quality of the item they were selling but make sure you research the track record of the item you're fitting.

edit: Which I now see thats what you're doing. D'oh.

See Rusty's project thread, he had a full 3" system on a Coupe.

it's between Prospeed and Pipewerx and OJZ for me

I have prospeed 100cpi cat, not cheap and it did work, needs to get to temp.

My system drops to 2.5" over the back axle for extra clearance, stops the system being boomy too. You need to bend the pipe away from the diff flange if you go 3".

They did a down pipe for my car too.

Had a quote from them for the Avant @ 650 all in not bad at all..... (with 100cpi cat)

Avant being easier to work on of course
(knew there was a reason to get one )

Was the 650 including a custom downpipe?

I have a Single Box 2.5" decat turbo back prospeed system, im really happy with it, very little restriction!

[GazzaG60]

2.5 is way too small for any real hp.

plus side is its way cheaper and most can bend 2.5

RE2500 is your car now turbo?

RE2500 has a 10v CQ converted to ABY. Stock exhaust is 2.5", Milltek is only 2.75" and splits for the post-cat joint, that's is fine for a RS2 spec (bacofoil express ), agreed that for anything over RS2 it's going to be an issue, get an exhaust cutout on there and 3" up to it

Thanks guys you all have plenty of knowledge on this topic!! It sounds from opinion that its not a bad idea but whats the difference on the cat from a cat 100 to a cat 200 (probably sounding thick here so apologies!) and am guessing its also illegal for me not to have a cat on!!?

[Jamo]

Not all cats are the same, some 100 cells will pass, others really need to get up to temp.

I have a 034 cat to go in mine which will pass any day of the week
