Outer Limits 4x4 Board

hey ppl,

just wondering what extractors ppl have fitted to their ferozas and how much it cost.. i dont want to spend a fortune but would like to get somthing that will give me more mid-range power (rather then top-end) as i think my standard exhaust manifold is leaky (has that hiss sound) which theoertically means the computer is out, which theoretically means extractors = better economy and power due to more accurate EGO sensor reading.. and is the standard exhaust pipe good enough? keep in mind i want low to mid range power not really top-end..

Without digging to deep in exhaust technology, for low/midrange torque 2 stage extractors (or 3y/4-2-1)are the way to go, pipe diameter shouldn't be too large on atmospheric engines because of the decrease in gas velocity max 2" I would say. Think the feroza guys here can tell you a lot more than me about the actual results from installing one .

cheers, Ron

Get a set of Hurricane 4-2-1 extractors and leave the back section standard.

I agree...as above

4-1 lukey headers and 2 1/4 inch exhaust right through

My down low torque has improved with this setup

I have Lukey 4-1, 2" system I have found that it is a bit noiser than other but better performance in torque.

I think any extractors and pipe would improve torque... Im sure some produce slight more than others depends on how technical you want to get
