dragonf6 Member 17 Member For: 13y 7m 29d Posted 16/07/11 04:11 AM Share Posted 16/07/11 04:11 AM Hi all,I've been told that if I put a cat back single 3.5 exhaust on my f6 I'll need to upgrade the injectors. Is this right? The car currently has a 4" dump, high flow cat and tune.Any help would be great. Link to comment Share on other sites More sharing options...

But being you already have a dump highflow cat with tune it may be fine. As for injectors that's only if you want more power than what the current ones will supply.

Im stumped on what to buy.. Link to comment Share on other sites More sharing options...

I'd heard that the f6 injectors were 44lb and were ok up to around 320ish rwkw. Link to comment Share on other sites More sharing options...

No need to buy the premium stuff if you only want basic upgrades.The xforce would be by far the cheapest, the nizpro is good value too. Link to comment Share on other sites More sharing options...
dragonf6 Member 17 Member For: 13y 7m 29d Posted 17/07/11 03:47 AM Author Share Posted 17/07/11 03:47 AM That $1200 is for cat back. Dam, must be paying a premium!!! $759 for twin 2.5 sounds even better. Link to comment Share on other sites More sharing options...

There are better brands out there for that money. Link to comment Share on other sites More sharing options...

Is this right? The car currently has a 4" dump, high flow cat and tune.Any help would be great.NO, injectors are ok for exhaust change a tune to take advantage of 3.5inch pipe, apart from that how dose your car perform with the currant mods?
