Il come down you can do it to mineFred@BTM said:
Ive had it done, not by mark fish though. TBH he charges and extortionate amount for what he does.
I did have a small blow on the part of the cat that is cut off but it is a great little mod. The revs pick up quicker and climb more freely, this may be because i previously had a crack though. Fred told me it wouldnt make that much of a difference but anything less restrictive must help when tied together with other mods.
I cant really say anything about MPG because of the blow i had but i wouldnt say much has changed.

The area increases by 60% so it is a big restriction. From what I’ve heard it is there to generate higher pressure in the cat = you get working temperature up faster in the cat = better emissions from cold start. Just drive the car some before MOT so the cat is hot and it will be no problem at all.
Also mind that stock air pipes to the inlet also have a 60% restriction. Just change the tubing and remove the acoustic valve and you will have a different car I can assure you.

Generally what happens when you go to motorsport professionals mate, especially ones with championship winning history behind them!

Only in this country is skill so undervalued.
shame you aint near but a 6-7hour round trip is a bit much lol
so how much are people paying to get this done then? becuase surely if its more than £130 your better off getting a decat and just swopping the cat out come each mot?
Wasnt meant to offend anyone or their work but you don't a need championship winning history to cut a bit of metal and weld a bit of stainless steel.
You need a good welder lol
I think i read he charges £200 to do it. Fred, you must agree that is alot for what he does?
Oh, mine passed an MOT a week later

what mark charges is upto him, but fair play to him he's a chamipionship winner!
I would be around 2 hours labour (£80) plus around £20-£30 in bits (would use flanges so you could unbolt the cat still) plus the vat
no offense taken at all, but welding/fabrication isn't as simple as people think, look at miltek even they f**k it up!

Lets not make sweeping statements.
Location/Service/Quality of work are all factors at work here. You haven't spoken to him. Yet you go on the attack. Very unfair indeed.

So very true

I really want to do this, the joint is absolutely crap on the 182s never seems to seal 100% properly.
I've got a mig welder and stainless wire, but what do you use to cut the cat? My hacksaws never seem to cut a straight line although it's probably user error

any one done this on the scorpion rs192 system? problem is the entry pipe into the silencer on the centre pipe is only 2 inch, will need to cut that out first but it's a bugger as I think the internal diameter of the silencer box is only 2 inch!
Black Gold Trophy
hmm I would have thought if it enlarges to anything it would be 2.5 inch? I'll have to get on the phone to scorpion and find out!

Have got a decat fitted and passed MOT yesterday with it.

Yeah I know the exit from the centre silencer is 2.5 inch, BUT unless the internal diameter of the perforated tube inside the silencer is 2.5 inch, there would be no benefit in welding a 2.5 inch entry pipe to it

lol, on a standard system I take it?

Hence my earlier comment about needing a new centre resonator.
IMHO you'd totally change the character of the RS192 system by enlarging that section. You will most likely get a lot more exhaust noise (it might even make it drone inside?) and might lose some lower rev range performance.

Had mine before and after tested with btb system, modded cat and inlets on the same rollers. 10bhp and 15lbft increase. And it WILL pass mot
Have a look at the mod BTB did on the cat. Nice bit of work to be honest. Holds the CAT higher too. £80 it cost to get done.

Does anyone have a pic of the standard cat that i could use to show them what i want cut and fabricated ?
Cheers guys !

To the guys that have had this done:
How much damage should i be looking at to get this done ? And will i need to provide the peice of pipe or will a decent garage be able to sort it out ?
Does the cut need to be just at the second sensor.... is that the part which is 2.5" and then get the straight 2.5" pipe welded onto there ? Also how long is the piece of pipe you guys used from the cat outlet to the catback section or will this differ per exhaust ?
Will this connection being solid prevent the exhaust from moving/flexing ?
Cheers guys, sorry for the 20 questions.. just want as much info before getting this done... As i daresay the garage will have never done this before...
