Put a flowmaster on my silverado today (5.3 liter), with a turn down on it. Its not enough sound, would putting a tip make a difference? Not looking to put a big oversized one, not somrthing that will stand out. I liked the idea of just a turn down since it isnt visible, but its barely noticeable when idoling. I also believe a little power was lost, tires barely screech now lol. Any advice?
Flowmaster?

Ditch the conventionally chambered muffler and get something else. Flowmasters were always power-robbing junk in my opinion/experience. The exhaust will get louder when they rust off, though.
On LS1 F-bodies the addition of a flowmaster muffler exchanges 10 rwhp for 10 redneck points.
Dynomax is a good idea, so is Borla. I always liked the tone of Magnaflow on a GM vehicle with an LS-based engine. It's mellow cruising, but has a good tone to it when you open it up. Loud all the time gets old REAL fast.
Clue #1 that it would suck.
Corsca is a higher pitched sound and pretty loud, but is very clean. My experience is with a friend's LS2 GTO with LT's/cam. It sounded perfect before the LT's and cam. After that, too loud by far! On your truck though, it might be just the ticket.
With the larger engines it's a cork. On a V6, maybe it wasn't bad, or the power-loss was not noticeable. LS1 F-bodies lose about 10rwhp as a rule, compared to stock.
+1, but some are better designed than others. Flowmaster is 100% about sound, they all sound the same, and they are cheap because they use cheap materials. If you want the sound of a chambered muffler, there are way WAY better options. I personally do not like a chambered muffler, either. The BEST exhaust system I ever heard was on my OEM Z06. It was basically a straight-through design with a perforated tube once the flaps opened at 3200rpm.
I almost got the $29 thrush instead...
I stand corrected!
I have a magnaflow, I just climbed under it to check it out. Anyway, very happy with it.

Magnaflow makes a great product. I have SLP on my mustang, it basically has two "resonators" which are just slight bumps in the pipe. those with the 2 high flow cats and headers means it is crazy loud, in a good way

I guess they have changed over the years. When I put the Flow Masters on my Mustang that was about the only High performance muffler you could buy. Mine are original two chambers and they get progressively louder with shorter tail pipes. But then the engine in my car is not at all "normal" either.
