Peace be upon you. I am offering for sale a "rockets" cutback and Y-pipe for a GMC Sierra 2018. The cut and Y are custom-made, not from a company. It comes with an electronic cut and its device. It needs some wiring adjustment, but the device itself is excellent and clean. If you want a sound clip, send me a WhatsApp message. I won't disappoint serious buyers. Location: Riyadh, Al-Sahafa district. (The sound is good, considered normal, not annoying, and it quiets down when the car warms up). It has a pleasant tone with light driving. (Reason for removal: I installed a different cutback and Y-pipe).
