Remember captin !

Must see a dyno to make sure it is still all ok after even if it is only cat back, due to yours already being tuned :)

Can anyone confirm that a 3.5" cat back is a direct replacement for a stock system and matches up with the stock cat.

Dont know the answer, but is this for noise?

I thought there was more restriction in the dump and cat than the rest of the exhaust.

Just spoke to Xforce.

FG Turbo cat back systems (that connect to a standard cat) only come in twin 2.5" and single 3"

A 3.5 and 4" can be fitted BUT must be altered to fit correctly to the std cat.

No longer getting exhaust fitted.

@ AdamIan69 wanted a 3.5 to match mods later on, the 3.5 sounded better than twin 2.5 IMO

Damn I got the twin 2.5. Lol. But twin 3.5inch cats and 4" inch dump. I also went the v8 exhaust so the turbo will be super quiet hopefully.
