Ok this weekend i am going to start fabing up exhaust for my iroc. I am running hooker shorty headers into a custom 3 inch y pipe that will y into 4 inch cat back. Now my problem. I dont want that loud of a car. I will be running a spintec muffler due to the fact that its the only company that makes a 4 inch in and dual out muffler. Now what I was thinking was running a muffeler where the cat would be then running the spintec out back. Any ideas coments etc?

 

I've heard of people running something like a Dynomax Bullet in the exhaust somewhere to tone something like this down.

 

Ok I decided on two mufflers. I will be running the spintech one out back and I will be running a 4 inch dynomax round muffler where the cat would go. The 4 inch muffler is a five inch muffler with 4 inch in/out. I got it for like 35 bucks from jegs. I am going to make it removable with v band clamps. I will post picks when its done.
