I'm thinkin about getting the RD Logics one piece turbo pipe for my HPI nitro rs4 3 ss. Is this a legal race pipe and also what should i expect to gain by instaling it to my car.
Yes, I believe it is a race legal pipe. I just purchased one myself and I keep hearing good things about it. Actually I also have the regular non-turbo as well, the only difference is that the header is a little larger. Good choice in pipe.
