Hi Chris, as far as I'm aware we can remove the centre cat completely and remain MOT legal as the 86 has another cat nearer the manifold. Which cat are you talking about?

The Berk pipe is a catted front pipe, like the stock one but better.

 

Sounds good. Price is pretty good too. Is this in replace of the second cat?

^ exactly that, stock one is a lot more restrictive so if your planning on a remap you really want to be looking at changing out the stock exhaust parts in order to get the most gains.

I will be honest I wasn't aware you would still pass emissions tests with one cat but that's why I joined here, Berk also do a decatted front pipe, I would have thought the two options were there for a reason but if you can get away with deleting the 2nd cat then brill.

 

The front cat in the manifold is the one that does most of the work, the 2nd is there to meet US & Euro5 emissions regs.

The 2nd cat is a necessary if you were to replace the manifold without a cat - I'll know soon whether this is UK road legal. If so, then this the cat'd hi-flow front pipe is a great option. If you're not going to replace the manifold, you may as well go for the de-cat option

 

Thanks Kodename, decat it is!!

 

Chris,

Do Berk make a 3" high flow cat? I am currently running a 2.5" overpipe and front pipe, but will be changing to a 3" replacement, to mate with the 3" Ultimate Racing rear system that is waiting for me at Fensport to be fitted, and the ECU then re-mapped. The front system & overpipe will most probable be custom made for me by Fensport (they have already done it on their race car), but I will need to procure a hi flow cat for the system.

No unfortunately not.


AVO do a 3" Catted down pipe, i'm not 100% sure on the configuration of GT86 as i'm still researching it myselfbut the exhaustAVO make specifically for their turbo application is only 2.5" piping.

Thank you for the reply. Whilst the most common 'large' bore exhaust for our cars is 2.5" dia., I want to go 3" for future proofing my mods, just to ensure I can stay ahead of the supercharger fans

. My logic is also, if the best solution for a turbo exhaust is the shortest possible outlet post turbo, then the larger the exhaust system, the better.

 

Cannot wait to get this on my car

 

Take it there was no update on this? I know others have managed to get Berk HFCs recently

 

I managed to supply some that have been purchased but my big stock order keeps getting delayed.

If you want one I can get one pushed through

 

Shipments arrived today!!

Unfortunately most is pre-sold but I have a HFC & Decat spare




BE QUICK !!!!!
