Hey,
Ive got a cat back exhaust only with cannon on my r34 Auto. IM considering upgrading the whole system to a turbo back, but im worried on doing this.
The reason why, is with this current exhasut the car sounds great, but while cruising at liek 80 plus and highway speeds etc, the car has a really loud droneing exhaust tone..
im not sure if this is because the autos are only 4 speeds, making the car rev higher causing the drone, or its the exhaust..
Basically, any guys with r34 autos or just mechanical minded people who know anything abot this, please offer their experiences or how to fix it?
any help would be fantastic
thanks in advance
Bryn
