I have acquired a MIP stinger pipe for my RC10gt on ebay. It is slightly smaller than the stock AE tuned pipe. On MIP online- they dont have any description of what advantages can the stinger pipe bring, only instructions.

I was told that there is a slight gain on the top end , but I am loosing some on the bottom, plus an increase in the noise level.

Is this true?

Need some expert opinions.

Thanks,
