I heve catless downpipes myself and the rattle you hear is the waste gate clappers in the turbos its perfectly fine ,If you install your cats back it will get rid of that sound
I have Pure Turbos in my car now and they use a new billet waste gate design
that basically eliminates that rattle ,with stock turbos my car sounded like a rattle can of spray paint right before every stop  |
Got it, thank you. This makes sense. Might just have to go with pure turbos then
