Lower gas mileage after K&N and exhaust upgrade
I recently added a K&N drop in filter for my 93 LS as well as a new exhaust system from the cats back. Exhaust is a couple of Magnaflows with an X pipe. Low end torque seems to be gone as well....Sounds AWESOME though. Any thoughts?

You may be burning it up in sound. When I put an intake on my car my gas milage fell off some also, then I noticed that I accelerated more often and more aggresivly (love the sound) If you have an "open" air intake you maybe taking in heat from the engine, which will rob you of power.

I think you're probably right about the sound factor....I just love the sound, so I tend to stomp on it a bit....and then psychologically because of the sound, you think you have all this power when it's still the little old 250hp engine it always has been. lol

Exhausts are a much more custom deal....depends, I just went in and told them I wanted a mellow sound....so that people know it's a V8. I also requested an X-pipe b/c I had read where that was the way to go for the LS.

PM John and get your name on the list. This will be a very worthwhile improvement.

I can vouch for the fact that K&N air filter yields a noticeable improvement.
