I have a set of side pipes with 3" Classic Chambered, and a set with 3.5" Howes. I had both sets dynoed on my car without any other changes. The Howes made alot more noise, but not more power. The only reason the Howes are still on my car now is because my set with the Classic Chambered mufflers are at a buddies house in another state.
Also, be careful what you ask for when it comes to noise. I absolutely have to wear ear plugs now, and on a big block car, the noise can be very fatiguing after a while. I can't take my car to work in the morning because my neighbors would quickly become enemies. I went to dinner with my wife with the car recently, and instead of the usual smiles and questions, I got dirty looks and wincing faces. My wife will no longer ride in the car because of the noise, but to some, this may be a good thing. There aren't many race cars louder than this.
Either muffler will be a lot better than factory and you will immediately notice the difference in power. Ease of conversion definately favors the Howe as you don't have to weld on a transition to smoothly funnel the exhaust into the 3" bore of a Classic Chambered. The Howe is two cuts, and two welds. Power and noise favor the Classic Chambered. I fit my transition to fit snug inside the 3.5" factory collector such that you can't tell the difference between my new side pipes and factory ones.
Spread your heat around and take your time welding. Otherwise, everything will move and when you mount them up, you'll notice the pipes not parrallel with the body.
Heres the Howe with a venturi style merge collector from Cone Engineering.
My next set I make will be a venturi merge collector with 3" bore. Good luck.
