Thanks for the tip! It deffinately worked! Power is back and gas mileage is back to normal. I remember when I added my cone filter on a while back, I did disconnect the battery after a while screwing around with it, but I didn't do it in the same way you described and with the A/C and all. I may try it again and see if my results vary this time.

 

GREAT, I'm glad it worked for you...good feeling huh!

 

According to the laest MM&FF issue (they did a muffler comparison) No mufflers yielded less hP than stock mufflers.

 

I tried the "cone" air filter this weekend and reset my computer the same way I did for my exhaust. It seems to be a bit slower, lagging in horspower. I think I'll wait this week before I take it back off. This is the same way the car acted tha first time I installed my cone filter setup, so I'm thinking it would actually need a "tune" with an SCT or something. Just a basic computer reset isn't enough for this mod.

 

I have the V6, and I have removed my stock muffler and added a tailpipe out to the back. Sounds awesome, even on the 6 cyl.

 

I have the SLP and I'm very happy. Where I live (Bosnia) noise from a car is not a problem. I have about 2000 miles on them. The only thing I don't like is the drone at about 1900 to 2300 RPM. I took a road trip recently, now I don't know if the SLP's have anything to do with this or not or maybe the computer is just jacked up so don't beat up on me. Driving at 130 KPH (80 MPH) the onboard computer said I was using 11.2 liters used per hundred kilometers. On the way back from my trip I punched it up to 200 KPH (125 MPH) for about 300 kilometers and the computer reported 12.1 liters used per hundred kilometers. How in the world can I get better gas mileage and a higher rate of speed? Perhaps I had a tailwind.

 

I get good gas mileage going about 80 on the highway.... about 27mpg. I have to gently touch the pedal and not be aggressive, but I average about 27 or 28 on trips. My cousin drives my car sometimes on long trips and she can only get about 24mpg... I don't understand, unless, I just know how to gently accellerate and when not to accellerate (coast).
don't forget to reset your computer if you havn't.... it will get your good gas mileage back as well.

 

The way I read that, it says you used MORE gas (12.1 liters) to go the same distance (100 kilometers) so that would be worse gas mileage whe going 200 KPH. Here in the states we're used to saying "miles per gallon" (or km per liter) which is just the opposite of the way you stated it. Make sense?
