As the title states, I need a hand... I've recently purchased a ba mk2 xr6t. finally acquired the cash for some go fast bits... looking at: 14psi actuator, set of deka's, valve springs. And this is where I run into trouble, do I go a xforce stainless system and a wog/ f6 cooler OR rapid v3 and just change the cat around.

Any help will be appreciated.

cheers, mat.

I think your better off getting the better cooler so get the V3, the exhausts on these cars are not too bad, changing the cat will free up alot of restriction.

Good luck with it

Agreed... Stock Cooler sux... Stock zorst good for 350rwkw...

Another vote for the V3 and cat, maybe centre muffler out too while your at it.

That should see low 300s (With some injectors) which is the limit of the ba motor and if its auto your 4 speed as well.

get a 5 inch 100 cell cat n remove centre muffler might want to put hot dogs in but its a personnel preference thing theres a few articles around about it
