Hi guys

I am looking at getting a Safari snorkel for my ute. Its a Td42 n/a blacktop. There are two options though and I am a little confused as to what to do. One is to discard the precleaner and the other is to retain the precleaner. What d you guys reckon would be the best one to get for me? I'm not fitting a turbo or anything and am just going to put a 2.5" 'zorst and tune it up.

The exhaust matter: I've found an almost brand new 2.5" exhaust and extractors on Gumtree off a 4.2 petrol leaf sprung ute. Upon looking at exhausts I have found that the petrol and diesel 4.2's are the same systems. My question is, do the exhausts on leaf sprung and coil sprung utes take a different route underneath the car? Would it fit my coil cab?

Cheers
