EXHAUST SETUP
The first thing you will probably notice…is exhaust sound. With the stock exhaust setup, the GT-R is very quiet. I started with replacing the catback exhaust with the HKS Legamax Titanium Tips. The exhaust alone did not make it any different from stock sound. Next, I got the HKS Resonated Midpipe.
The midpipe & exhaust combo did make a slight difference, but not what you’ll probably looking for. The car was louder at startup, on idle, and barely at wide-open throttle. In terms of in-cabin drone, it was mostly noticeable on highway cruising speed around 65-70mph (below 3K rpms).
Finally, I decided to jump to the next stage of going FBO. I got the AMS Alpha 90mm Downpipes (Catless). This setup was amazing! It eliminated the drone I had with the HKS midpipes, improved sound, tone, and was not too obnoxiously loud when cruising. At wide open throttle, it is LOUD! Just perfect!
*Side note: I replaced my midpipes 3 times lol. My first one was the HKS Resonated, and after installing the Alpha downpipes, I replaced the midpipes with a COBB catted midpipe, thinking that it would reduce drone & fume smells. It did. 5 years later, the Cobb midpipe snapped due to salt/rust build up, while driving in winters (DETAILS –> HERE). So I went back to my HKS Resonated midpipe. Both setups we’re amazing, no drone, and no fume smells.
