M4 Exhaust Full System Black GP19 with canister ZX6R ZX6 2009 - 2025 KA6982-GP19

It sounds amazing! Nice deep rumble at idle and screams at higher rpms. Instructions aren’t the best but common sense will get it done.

A bit disappointed

I recently purchased an M4 exhaust from Bills Exhaust, and while I was initially excited about the product, my experience left me with mixed feelings. The delivery time promised was up to six weeks, and unfortunately, it took the full duration to arrive, which felt a bit excessive but was manageable. However, upon receiving the exhaust, I was disappointed to find a significant scratch on the carbon fiber muffler. While I contemplated pursuing a replacement or warranty, I hesitated due to the lengthy wait I endured for the original delivery. I feared I might face the same frustrating delay again. Overall, while the product itself has potential, the delivery issues and the damage upon arrival hindered my satisfaction. I would recommend considering these factors before making a purchase, especially if timely delivery and product condition are a priority for you

Install was simple. Instructions were good. Shipping was fast. If i need another exhuast I will be buying from here.
