This may be a dumb question, but bear with me, ok? There was no exhaust on my '70 GT when I got it, so I quickly fabbed up an exhaust all the way out the back just to keep the fumes from coming in through the rust holes in the floors (which are now being repaired). I had a nearly new complete exhaust from a '73 Datsun 240Z that had been in my garage for about 8 years, so I used and reshaped pieces of it to make the exhaust and even used the small stock barrel muffler. Now, I just recently purchased a very good GT rear resonator with dual tips and I had a question regarding what muffler to use with this. The short little barrel muffler on it now was really fairly quiet when I ran it on the Datsun with a straight six, but either due to it's age or other factors, it seems excessively loud on the GT. I was wondering how much difference the resonators really make and if this would just amplify the already too loud exhaust? I'm wanting a fairly throaty exhaust note, but I don't want to get too overly loud and offend the "noise police". I am considering replacing the old Datsun muffler with a turbo muffler of some kind from either thrush or dynamax, and I was wondering what some of you might have tried and what you would recommend. I am wanting to keep the exhaust fairly cheap right now, especially since everything on the motor is stock. I've used the dynamax turbos and turbo II's ($14-$26 and widely available) many times over the years on V8's, but I have no idea what these would sound like on the GT with the 4 cylinder and resonator/dual tips. Has anyone ever used one of these on a GT? Also, would this type of muffler have any affect on the performance of the stock engine, either good or bad? How does this compare to a stock GT muffler? As I said at the beginning, this may be a dumb question, but I don't want this thing to sound like a swarm of bees going down the highway so I thought I'd see what some of you have used on your GT's and go from there. Thanks for any replies on this topic and sorry for such a long post.
