I love Top Speed CBE. I really don't care about the NAME of the exhaust company. You can custom weld cheap parts and still can gain a lot. I believe that what you pay for the CBE is like the quality of welding, materials used and the brand name. For example, I know that Meisterschaft CBE always come out with crazy top quality and it sounds amazing. But it doesn't make much of gain I heard. My friend had Amuse R1000 and always complained about it. He runs the track a lot and told me "I had R1000. It was garbage. It easily exceeds race track dB limit by 20dB. Couldn't even use them." and they nearly cost like $3000 or more. so my point is don't get caught up with the NAME of the brand. TOP Speed is really cheap and has GREAT sounding. I will get Top Speed CBE one day if I get money. Thanks for the great review Dai.
