Just a few questions!!

[wcrispino]

good day fellow supra lovers!!! I have a question and wouldn't mind getting some feedback. I have a 93 supra with a 3 inch cannon exhaust. I think I have a cat converter and 1 muffler, a fairly small muffler and then a cannon muffler at the end. My question is how can I make the car sound quieter without affecting the performance?? It is N/A.

Also I have noticed that after I put in an air filter box ( I have a pod filter and put a box around it) , the car seems a bit slower. The air filter box is plumbed out to the front.

And lastly what do they mean by putting in a cold air induction system? what items does it involve attaching?

Thanks and hope all you supra nation people can help a fellow supranese!!!!!
