Has any one put an electronic exhaust dump valve in their G35 coupe 03-05?
Planning on installing one. Want to know your thought.

 

Yep.

You lose lotsa low end torque when open.

Makes your car sound like American muscle.

 

Do you regret putting in on? Why would you lose low-end power. No back pressure?

 

^ What does that really do? Doesn't it just allow you to bypass the muffler and create more HP and Torque I thought by not being so constricted???

 

Surprise, surprise our cars need a certain amount of back pressure or they'll lose torque. One of the worst things you could do to any car would be to put on an exhaust system that was too large with any restriction. Welcome to the 21st Century....Dump Valve? (no thanks)
