hey i just put a single in with dual out on my 4.2 97 has 3 1/2 inch echo tips sounds ok hope i did put on a good systym ..... IS the true duals with two muffelrs better ?

 

I had the same for a while, and I loved it. I changed because I had a converter break up and blow pieces downstream into the muffler. Those baffles work great on exhaust gasses, they also act as a dam for any objects coming through. I know objects are not supposed to be coming through, but mine did. The pieces were trapped in the muffler, and they rattled like crazy. I installed a magnaflow dual in single out, and it's quieter, but I like it okay.

 

tight yeah i like mine i just had to cruise it down the block to hear it agian it agian ..
Has anyone dyno the exhaust with a flowmaster on it how much increase in ho does it put out it does seem to flow alot better and it seems the acceleration has increased . my next step is probly the mac air intake cant wait to see what that does.
