The HP loss is significant but you're probably right, on this application he wouldn't notice. He asked for a recommendation on mufflers and I gave him my opinion. I have been doing exhaust work since 1982 and have some experience in this area.

It's a very good muffler, low restriction and much quieter than a flowmaster.

In my old 76 Silverado I just ran turbos that I got from the local muffler shop, they sounded good, not to loud and not to quiet.
I've also heard that "flowdisasters" are the worst performance muffler out there, who knew they were such pieces of $hit??
But dam it man, they were all the rage back in the day - everybody I knew either had them or wanted them. Cp
Sounds like you had is what I refer to as an installer turbo. They are usually a generic type of muffler that is less restrictive than a stock muffler and they have a decent sound. It's a good economical choice for the average stock to mild performance street car.
I was never impressed with a flowdisaster muffler. The muffler they offer now has a better physical appearance than the original ones that were shaped like a box and I never cared for the way they sound. That's just my opinion and apparently the guys with the 5.0 Mustangs thought otherwise. To me the kids with those Mustangs are what created the whole flowdisaster craze. When I have a customer ask me for my opinion on what "sounds good" I'll tell them that's subjective. What sounds good to me might not be what they like. Personally I like a little sound and I have customers that like the no muffler straight pipe sound. When a customer asks for something that sounds like a flowmaster I will warn them about the performance disadvantage but if that's the sound they want I'll get sell them a "flow".
I have a group of guys about 100 miles from here that won't let anyone touch the exhaust on they cars they build but me. A few years ago the one put a dyno in his shop and one of the guys at another dyno shop that he shares info with actually set up a sbc on a dyno just to test mufflers. Out of all the mufflers that he tested the "flows" were by far the worst. These are the guys that got me started using the term flowdisaster.
