The best = one that matches your planned power requirements, low back pressure, fits without hitting the body and does not DRONE. Manta, Nizpro, Xforce are but a few examples of what is on offer.

Chaos310 Donating Members 228 Member For: 11y 7m 18d Gender: Male Posted 18/09/13 12:47 PM Share Posted 18/09/13 12:47 PM I run manta 4" to twin 3"s... in top gear at 120 its a little droney, but pull it back into 5th and cruise and the drone goes away.I only make 519hp at 17psi and I'm happy with the system. It bolted in well and is top quality.NB: if you install it yourself, buy new mount rubbers and make sure the car is level, like it would be on the road, otherwise you tighten the exh and it will not sit 100% nicely at the tips. the old rubbers stretch really easy and mine knocked a little, new rubbers and she's all good Link to comment Share on other sites More sharing options...

unclewal Donating Members 583 Member For: 13y 6m 30d Posted 19/09/13 02:46 AM Share Posted 19/09/13 02:46 AM I run 4" to twin 2.5 xforce and its perfect, quiet as with a nice note and still makes a lazy 600hp. Zero drone and good price point for me. Guess its down to what you can afford and what you want to get out of your ute Link to comment Share on other sites More sharing options...

Ran about 550rwhp. Link to comment Share on other sites More sharing options...
AdamIan69 Bronze Donating Members 401 Member For: 10y 11m 29d Gender: Male Location: WA Posted 22/09/13 03:03 AM Share Posted 22/09/13 03:03 AM I'm running a 4" dump twin 3.5" body cats, 3in twin to the mid muffler, then 2.5" out to the resonators. Sounds good in my opinion as its quietish and it allows me to retain the 200mm cross member that normally gets removed with big diameter single exhausts. I also have more ground clearance then I would if I had a 3.5 or 4" single exhaust. Link to comment Share on other sites More sharing options...
