exhaust options for twinscroll engines
 

Are there any other options out there for a full 3" system with sports cat other than the scoobysport and Milltek?

My criteria are: Full stainless, proper 3" set up with 100cell cat(either in DP or centre) and no more than 4" tailpipe(straight or slash cut, not rolled)

prices and suppliers would be good to know. I've searched the net but it's full of confusing info on the twinscrolls.

thanks

oh..and nothing noisy!

Powerstation with their Miltek

RCM with their Janspeed (I think), I have this as a decat but I am sure they would be able to do a high flow cat version.

I think API Engines do one as well.

HTH.

I run a system from Mocom Racing pretty much as you described. Passes all noise regs of UK circuits, is MOT friendly and needs no cel fix.

Downpipe has a divorced wastegate pipe to ensure minimal disruption to the exhaust gas and is coated with a high temperature coating, as used by WRC teams, to retain the heat within the system keeping up gas speed and preventing unwanted heat radiation.
Mid section contains 100CEL cat ensuring MOT compliance and contains a resonator to prevent the boominess at cruise associated with many aftermarket systems.
Backbox is pretty much the largest that can fit within the space to keep noise levels at a minimum with a slash cut tailpipe following the rear bumpers natural profile to look unobtrusive.

Might be worth a call tomorrow :thumb:

I like the sound of that MR400. Not sure about the divorced wastgate though. I thought the general belief was that a full open neck provided better results. I'll do some more research on it.

Who has actually tested it on the twinscroll ;)

good point. I've mailed Mocom for more info. Sounds exactly what i'm after though. Site says it's 'under development' though

what sort of price did you pay for yours? PM me if you'd prefer
