I have ported Manifolds on the car but had my Standard up pipe on with them but after my last map I got 440 bhp and 405 lbft and the up pipe has Finally Split so got a Harvey smith up pipe can I pull the down pipe off to get to the up pipe or do I have to remove the turbo
Thanks

 

Can be removed from the bottom. No need to remove turbo. you will need to loosen off the o/s engine mount and jack the engine up a little to get it out

 

Cheers bud
