Quick Question

[liamg89]

ok so im a mechanic by trade, got my bf xr6t last week and just ordered a xforce 4 inch dump, high flow cat into a 3.5 inch single system.

then a work mate tells me it may cause issues to the engine as a first mod to it.

was just wondering if anyone here had any experience with doing this swap up and if it all good to do?

any help would be much appreciated.

Thanks

He is correct in that it will want to overboost from standard settings which will create boost cut and cause possible engine damage.The car will need a tune to go with the exhaust,you may as well add some injectors and better cooler to the mix if you don't already have them.

cheers mate. might hold off on fitting it till I get sh*t sorted aye

[liamg89]

so what is the minimum I need to do to fit the system without blowing up the engine? if its too much in one hit I might send exhaust back and do the other things first?

[liamg89]

would a flash tuner fix the overboost?

Custom tune needed as a minimum, sct xcal 3 + tune= upto 1600?? Vcm suite= 7-800
