Hey guys

Pacmaker 4480s work better than the 4495s on the VCT donk. 2.5" system is all you need, but 3" would be suitable too. You want straight through mufflers to limit restrictions and I'd go for a reasonable size centre muffler (18" to 24" long) and a rear resonator (especially if it's auto).

mufflers I am running now. But that and air intake is running 146rwkw so obviously what I have done has worked. |

Yeah VCT mate. Last one I went to was 137rwkw and since then I have done the air induction setup
so is breathing a lot better.And the other cars there on the day ran the sort of figures I would have expected them to. There was a BAXR8 there that ran 199rwkw which is about spot on so I believe the dyno is there is as accurate as any roller is. Here is the dyno sheet, ignore the date as it was only about 3 weeks ago.

Definitely recommend the 4480s over the 4499s. Better suited to the VCT set up. I mated them with a high flow cat and 2.5inch redback system and was happy. Little drone as well if that worries you.
Cheers, Ian
