i need help with the exhaust im getting this includes the headers, on a 91 chevy k1500 5.7
1991 k1500 z71, 3-inch body lift with 315x75 mickey thompson atz. all new xplod speakers to replace old speakers. brand new 5.7 liter 350 with flowtech midlength headers and true duals into one x pipe muffler
Flowmaster is number one exhaust in my book..Gibson makes good and affordable headers
I went a slightly cheaper way on my 1996 K1500. I just went with cat back exhaust with an x-pipe after the two cats. I absolutely love it and wouldn't want a different sound. I originally had it without the x-pipe and with cherry bombs, but went with the x-pipe. Really smooths out the sound. Much better!!
I haven't really been able to find anything but Gibson headers for my suburban...unless someone else knows where I can find them for the 8.1L


I'd say if you can find some fair priced long tube headers like pacesetter pick them up. The long tubes will offer you a much great HP/TQ increase. If your looking for some of the best I'd recommend dynatech. There pricey about 1100 bucks but there good. Also exhaust wise I'd probly go with 2 Magnaflow high flow cats and Magnaflow muffler. You'll save alot of money if you don't buy the whole package but get the 3 parts then take it to an exhaust shop and have them weld in the pipes. I'm not sure exactly what fits your truck but websites like truckaddons.com and others can help you get started.![]()

When I put the new cat in a couple of weeks ago, I went with a catback system with a magnaflow muffler 3" tubing and the mandatory chrome tip. $340 and it sounds good. Sometimes a little noisy for me, but overall I'm happy. I did bump the sound system this weekend to compliment the tone outside with tunes inside.![]()
There is no way to happiness....happiness is the way.

If you want something loud then I would have to recommend the flowmaster 40 series, with 3" pipes and 3 1/2" Tips. If your worried about emissions I'd get two high flow cats instead of taking them off. Top it off with a nice manual cutout before the muffler and it will not only sound loud but nice a deep as well. Thats what I had on my last truck and I got compliments everywhere I went. Best part is, under 400 bucks. Minus the high flow cats which aren't important if your not worried about max performance.![]()
You could also just straight pipe it all the way back. The setup I have on mine is actually a dual exhaust setup.
For one, I have the factory exhaust system which is still fully functional.
The other, I have electric cutouts before the cats that allow me to open to the unbaffled sidepipes.
I'm loud when I wanna be...and stealthy when I need to be...hehehe
