2017-2026 M8 BAGGER - BIG BORE 4.5

Took a little while but i knew what i was waiting for. Customer service is one if the best i ever contact in my life. I made a mistake and something melted in my exhaust pro flow header, so i tried to remove it and made it worse! So i called them and Grayson was very good with all my concerns, they will fix it for me for a very little price. I would pay 3x more to fix here in my city, and still wouldn be as good, but these guys are no joke, they make it happen. I will send it to them and get the job done right for a very good price. I really appreciate you all at SP Concepts. I 100% recomend this Company to anyone considering going for the best. The exhaust sounds absolute nuts when you ride agressive, and when you put it in cruise control, this thing sounds perfect for a long ride! I am grateful i chose SP Concepts this time. Peace!

Sound great, easy install and received faster than expected

Awesome product
