AP –
got it too fit, but the pipe sizes were larger than the OEM so the heat shields wouldn’t wrap around completely. i’m glad in a way that the pipe is larger though, since i think it will hold up longer.The OEM design is just bad though – there’s no stress relief between the two banks of the engine, meaning considerable strain on this pipe as it heats up.
