First off, the fabrication quality of these mufflers are, dare is say it, quite REMARKable. All the bends and welds are clean and professional. The tips are sized so well that they look very clean with my 370Z. The mufflers are very light and a dramatic weight reduction over the stock mufflers. I’m will to bet that there is a horsepower increase for bolting these things on Especially knowing how much restriction is in the OEM muffler. No matter if your Z34 is all about performance or if it’s a show car, these are not a bad choice at all. Install took me 30 mins tops. The toughest part was taking the exhaust hangers off the stock exhaust. Lastly, The sound... 100% VQ Roar. Depending on your setup, these mufflers can be loud, but controlled at the same time. I’ve had mine for about 6 months and I would have to say that throttle level determines the volume of these mufflers. At wide open throttle, they are loud!!! However, speeds below 75mph, they are very well mannered and low. Most catbacks create a sound for the 370Z, these mufflers elaborate its original sound which sounds much more unique in my opinion. Overall, these mufflers are the exact answer for someone looking for a great, yet cheap exhaust upgrade. These are best in business, hands down. If you own a NISMO 370Z, don’t waste your money buying a crazy expensive exhaust unless your going with forced induction. NISMO H-Pipe with the Remark Mufflers is all you need to match quality with performance and sound.
