3" Exhaust options?
My stock cats, H-pipe and mufflers are costing me 60hp on my new 402, compared to open headers. It seems clear the cats are clogged. I want a X-Pipe that works with my stainless works headers, and Random Technology makes two versions with high flow cats, both reasonably priced (for full stainless steel, with high flow cats) for ~$750.
One is 3" all the way, front to back, and requires 3" mufflers.
The other starts 3", goes down to 2.75" immediately after the cats, and then reduced to 2.5" right at the muffler, to go to stock size mufflers.
So I can either get the 3->2.75->2.5, and then I've got tons of options, or I get the 3" all the way, and I need 3" mufflers.
Is there any 3" muffler system for the C5 that isn't obnoxiously loud? I figure 99.9% of people who go 3" exhaust *want* it to be loud, and no one has ever asked for a 3" C5 muffler that doesn't make your ears bleed. Even if I did get one, would it (by virtue of being quiet) perform no better than an equally loud 2.5" muffler?
Thanks,
Miles

Miles both Stainless Works and Random Technology make a full three inch system with mufflers. You just need to give em a call. You are right with that much displacement you do need to exhale!
