Gr33k123 Posted April 16, 2017 Share Posted April 16, 2017 HKS Silent Hi Power Catback for 32 GTR Hi all, I'm considering replacing my catback exhaust on my 32 gtr. Hearing a bit about the hks silent hi power exhaust, anyone have any details on this catback i.e. any restrictions, noise at idle and high rpm (given I'm running 19psi). Don't want anything too loud and needs to meet noise restrictions at wakefield park. Also if anyone has one for sale in the sydney area what price are you chasing?

niZmO_Man Posted April 16, 2017 Share Posted April 16, 2017 It's not exactly silent, but should be quiet enough for Wakefield. I had no trouble at Eastern Creek south.

djvoodoo Posted April 16, 2017 Share Posted April 16, 2017 Does the HKS Silent run a 2.5 inch neck down in the main Cannon? I thought that was the main difference between the silent and Hi Power exhausts?

niZmO_Man Posted April 17, 2017 Share Posted April 17, 2017 I thought it was a bigger mid muffler. I didn't notice step downs but it probably has it.
