I was bored today so I took the muffler off of my '91 to see what it felt like. Wow! What a difference. It seems like I gained a little bottom end power. The car really pulled after 4k rpm. It sounded terrible, however.

What I found interesting was that shifts were a lot smoother without the muffler. Before things felt sticky and it felt like I must be damaging something every time I shifted. I figured I must be imaging this, but on se-r.net Merlin Johnson wrote about the "Good positive engagement of gears whether upshifting or downshifting" after installing a Trust exhaust. Why is this?


and I don't suppose anyone wants to sell me a used Trust exhaust?

Whe you take off the car or muffler, you usually gain high rpm horsepower and loose some torque becuase there is less back-pressure. 4,000+ is about right to when you start feeling it...

Less backpressure equals les torque, which means more power loss between shifts. Hmmm....maybe this is why Hondas shift better!!!! (less torque

)
