I plan on making a driving video just for the sound ! I installed these 75mm stacks from TTT. Their ad seemed humorous about scaring the guy in front of you at the track -BUT-these things sound glorious! Never driven a Datsun race car , but the only thing missing is an open header -lol. OMG they sound good. I hope a video will capture the sound correctly. About everyone I've taken a ride have been blown away.

Would have loved to go for a ride when we were at Zcon.

If I had been feeling better we could have changed a radiator and then gone for a rip!
