Backpressure?

Backpressure?
I drive a 94 LS 5-speed, im having a backpressure problem in my exhaust, i have a AEM SRam intake with hi-flow cat, and 3A Muffler fireball series 3 1/2"tip, Ive heard mounting the exhaust at an angle alows better flow through the exhaust, and heard bigger piping would also help, guess im asking what do i need to do to get rid of the backpressure sound so its nice and smooth sounding.
Also was wondering if the gsr upper intake manafold bolts onto an LS, if it does would this be like buying aftermarket upper intakes.

Back pressure is pretty much a myth.
Whats the problem with your exhaust?
Your piping size should not be larger than 2.25", since you're still running a stock motor, the head can support much.
Anything larger than 2.25" you'll lose power.
and no a gsr intake manifold won't bolt on.

Why would you lose power with a piping larger than 2.25"? Wouldn't that allow for better flow?

Any NA motor needs a certain amount of backpressure. The pressure causes a vacuum effect that "encourages" exhaust gases to be released quicker.
Cant imagine mounting the exhaust at an angle allows for any kind of flow improvement...the less bends the better.
