down pipe size

[neil]

Hi , at the moment i have a 2.5" down pipe on my leon cupra with a 200 cel cat and there is a group buy on another forum for a 3" down pipe and cat . Thing is , would i notice any difference between the 2 ? Is there going to be enough of a difference to warrant changing it ?
cheers , neil

Negligible difference. Who's brand is the cat?

As above, spending your money on a decent exhaust manifold will get you more power for the money, if spending on the exhaust side is what you're after doing.

If you're running a K03 or K03s, then the JBS manifold is a worthwhile investment - it's listed on their website.

If you're running a K04, then you'll have to wait like the rest of us for them to release it
