EF-EL 6cyl; 2.5in Cat Back Exhaust (8-10kw gain)?
I was just reading an autospeed article about Jim Mock and he claims that a madrel bent cat back exhaust generally gains 8-10rwkw on an EF-El 6cyl Falcon.
Has anyone's 6cyl EF-El got this sort of power increase after having a cat back sports exhaust fitted.
He also reckon's this is the first mod you should do and you don't need to modify your intake unless the car pulls more than 140rwkw.
He also said that the EF dual intake pipes work better than the EL and AU single bore pipe.
Another thing he said that a pod filter inside the airbox works alot better than an after market drop-in panel filter.
Anyone agree/disagree with these comments?
