Eh, I gotten used to it...but I think at the start of next year I am going to resonate it. Flowmaster actually makes a resonator that should match with the 80 series perfectly. Agreed that it sounds nice at idle-3k, anything after that starts sounding...ricey.

Also Curt, remember exhaust velocity...my 3500 puts out less velocity now than it did with the factory exhaust (I did the full exhaust swap and not just a muffler swap), and puts out less than a 3800 for obvious reasons. The tone will sound deeper than what you heard from mine. *Scratches head for a second or two*...didn't you say you were gonna keep this a sleeper? Maybe go with a stock F-body muffler...you will get your flow w/o the noise that way.

Yup...had one on my SLE

Hmmm.. thats a thought. My '87 Camaro V6 started life with a single inlet, dual outlet on the same side. I think I'll start with just a single in/single out and see what it sounds like.

The constant drone doesn't bother me much...My hearing is pretty much shot, so things sound different to me to start with (I can't hear high frequency stuff) It'* kinda like having the bass turned way up and the treble turned way down on everything.

As to sleeper...It has to *look* like a stocker. Doesn't have to sound like a stocker (most of the victims have the stereo turned way up anyways

Well, did it yesterday. went with a Flowmaster knock-off made by IMCO (no packing, just chevron shaped baffles in the muffler body). single inlet, single outlet, no resonator.

Sounds pretty good, not much louder than the stock muffler, with a little bit of burble to it.

I haven't dropped the center pipe to look up inside the exhaust manifold. Picked up the exhaust gaskets this weekend and figure on dropping the manifold over the Christmas holliday long-weekend.
