Wats better a 2.5 inch system or a 3 inch
Cheers

 

i suppose it depends on what level you tuning your car too?

 

Well atm im jus fittin an apexi pfc 440 injectors , front mount , hks induction kit
Its currently got a straight through de cat'd 2.5 system
Jus wondered if its worth goin 3 inch yet
Cheers

 

what model,power gains expected?

 

Hoping for ova 300bhp wen its mapped

 

Its a uk awd turbo

 

Well that answered my question
2.5 will suit your car to that level though your going to have to update the turbo and fuel pump for 300bhp, model year would help, im taking a guess that its an MY99/00 car?

Its a 1994 bud , its runnin a td05 turbo , and will be fitting a walbro fuel pump and also a different map sensor b4 the remap , jus wondered if id get a better out *** with a 3 inch system ??
Cheers

 

td05's i believe can reach 350bhp, although yor 440's i think will need upgrading.
i would go for a 3" system at 350bhp.
although speedbumps will be more of an issue. they keep clipping my centre resonator.

 

If its a 94 it wont have 440's, its going to be running 380's.

Tony

 

Will be puttin 440's in to replace the 380's mate

 

2.5 inch fine for that power level.

It will need either an after market ecu or a chip (mapped of course) otherwise it may cost you a new engine
