OMG new Janspeed Ultra Performance exhaust system

[Berty]

There's a video of it on youtube but I don't think the video really does it justice.

i have one fitted its the supersports ,when i get back from holiday il try and upload a video ...theres a nice tunnel near where i live sounds amazing

the Trophy has a sports cast as standard btw. #-o

So is the cat on the Trophy different from the standard 182??

 

[Cue]

not sure - i know the trophy's is a 200 cell though, not a standard 400 cell..

Since the Trophy has a 200 cell cat as standard, but constricts the diameter down to 2.25" at the exit, would it be possible to modify the standard cat to get a 2.5" system from the manifold back or would this damage the standard cat? I want a 2.5" system but I don't want to pay for a replacement sports cat just to get an extra 0.25" as that's a lot off money for a bigger pipe. I'm very tempted by the KTR Ultra Performance exhaust, but does it make that much difference to the performance of the car if you don't have a 2.5" system all the way from the manifold?

Cheers

I think this is the mod done by Mark Fish think its around £150- £200 though.

Have a search as there are some threads about this

i have had Mark Fish Cat mod done. Alot cheaper than a whole new cat especially as the CAT is already 200cell. Cost me approx £125 all in

Does this modification affect the performance of the cat? My only worry with something like this is that in cutting into the cat up to a point where it's diameter is 2.5" you end up removing some of the cells

just CAT housing......CAT remains uneffected

 

[murcod]

Yes, the outlet housing on the stock cat is a conical shape. All you'd have to do is cut the end off until the outlet is 2.5" and then weld a new piece of pipe on.

BTW I've measured my 2005 182 Cup and the cat outlet is more like 50mm outside diameter. So it would be well under 2" diameter internally.

I've just come across Vortex Exhausts by Torque Exhausts. I'm a bit sceptical about their claims, but I'm not sure either way. Has anyone done this themselves or know anyone who has. It's pretty incredible if true, hence my feeling it's smoke and mirrors.
