Peace be upon you. I am offering a "rockets" cutback and Y pipe for a GMC Sierra 2018. The cutback and Y pipe are custom-made, not from a specific company. The electronic cutback comes without its device, and I don't know if there's a leak or anything else. I have no experience with it because I bought it with this cutback. Whoever wants a sound clip, send me a WhatsApp message. Please refrain from calling, thank you. I will not disappoint the serious buyer. Location: North Riyadh, Al-Sahafa. (The sound is good, considered normal, not annoying, and it quiets down when the car warms up). The sale is negotiable, God willing. (The price is 800).
