Oh god I feel like such a newbie lol, thanks for tolerating my idiocy, I thought I read about the 71r being good up to 400hp guess it was crank? Idk. And I knew it was 2.xx but I couldn't remember. What are the 71r's capabilities

 

I mic'd my SSACC exhaust and the most narrow sections were 2.3" ID. Some of it was much larger due to the slip joints, but that isn't indicitive of the entire system. The tips are 3" double walled

 

I don't think I can hold out much longer...must buy exhaust...
