Suburban Flowmaster Exhaust

Hey all, I think I am going to buy a flowmaster cat back system for my 1996 Suburban. The one im looking at is part #17122 on eBay for about $300. It's pretty basic, but I don't have to weld anything it just bolts right up to the stock hangers and cats. It exits like the stock does, behind the wheel well. It is fairly affordable and seems to suit my need as I don't want anything flashy really. I just hope it gives a nice low grumble. That's all I'm really looking for. The stock exhaust that is on there right now sounds kind of.......I dunno....weird? It's not bad, it sounds good, but I dunno it just seems a little different to me. Is it just me? Does anyone else think that? I think I am just used to my 93 TBI, which gave a nice grumble at idle and even on accel. My question is this. Will I see any sort of improvments in gas mileage/power? I am getting about 10-11 MPG in town right now. Don't worry, I'm not trying to make my 5,000 pound suburban do 27 MPG, I'm just curious if I will end up with any gains vs. the stock exhaust system. Also does anyone else have this type of setup on their burb/truck? Just curious as to what people think of it. Thanks!

You probably won't notice a difference in gas mileage, unless your foot gets heavier when you hear that rumble. Mine did after cutting off the mufflers that were on there when I bought it. I have never heard a quieter truck than mine with those mufflers. I swear they must have been for a caddy... Going full throttle up a hill, the guy behind me on the trail couldn't hear anything.

Well I've had alot of thoughts about this since I can't get a chance to work on this in the bitter cold. I decided on just welding in a Flowmaster 50 Series SUV/Truck muffler in the stock position. I will be using a stock tailpipe for a 95 suburban (I like the way it curves back, and it was cheap). I was able to score the muffler for cheap, which saved about $250, which I spent on a K&N air intake (but thats a different story). I don't have the muffler yet but it looks like the dual inlets should match up to what I have now. I am just a little skeptical about how the outlet will match up with the tailpipe resting in the stock hanger. It has a center positioned outlet. It seems to me that the tailpipe might be at a different height, and too far to the side, to perfectly match up with the muffler. Have any of you used that flexible tailpipe they have available? This would solve the problem and make the job alot easier, I would position it on the outlet of the muffler to fill the gap, and curve over to the tailpipe. It would be perfect.....if it works well that is. I dunno if it will crack or rust real easy or what. It's cheap and it will work perfect to install the thing so it is really tempting. Any ideas?
