I was planning on runnin at the track. But only runnin a factory gsr rite now. Everything from intake to exhaust to head unit. I was wondering what simple slight non-cost mods can I do?

What I had in mind was to unhook the intake from the intake box and just leave it faced forward for the mean time. Also for the exhaust part I was thinking about unhookin the axle back factory muffler and just runnin it like that. How loud will it be and will vtec be heard loud?

^^^ Would this be safe to do or will it harm the car???? ^^^

Does neone know the stock diameter of the factory exhaust system including the inside of the cat?

 

Do not unhook the intake, if you want to do anything take the top of the box off and leave the filter hooked up. this will help top end a little, but you will loos a little off the bottom end.

Do not unhook the exhaust either. this will hurt the performance of the car, not help it. And it will be stuipd loud. Most tracks have some sort of noise restrictions.

 

so jsut leave the exhaust alone? What is the diameter in inches for the factory exhaust?
