Hey guys

Next week will be doing my first small mods to my F6

Looking at xcal 3 tune, airbox modding/piping, hi flo cat and POSSIBLY a new dump pipe

From what I have read, people have mentioned a 4inch dump? What is the best brand for this and how much should I expect to pay?

The tuner mentioned something about it possibly being difficult to run on a stock exhaust system?

I would love to go whole exhaust, but its just a money thing and plus I kind of like it being a bit of a sleeper

New dump worth it or just stick with the tune, hi flo cat and air box changes?

Thanks in advance

From the research I've done on here I think if you go dump and cat you need flapper mod on turbo(I think) as its hard to control boost.Guys have run low/mid 300's with just hi flow cat.If you wanna go dump and cat and keep rest standard then xforce,advance,SMB and maybe CES do that and I know advance dump/cat bolts straight onto std exhaust

Thanks mate

Ok I see what your saying, may have to get a quote on flapper mod too

What do they do exactly to the turbo?
