For some reason after driving hhigh speed for about an hour, I notice the car become extremely lazy... as if theres extra weight in the car...

it just doesnt have the same pick up as I did when started the trip

anybody have any solutions?

 

it's because your body is used to the speed of the car...so it doesn't feel as fast the longer you drive. There is nothing wrong with your car...and definitely nothing wrong with your A'PEXi cat-back....

 

Its your engine being tired...try running 10 miles straight...then jogging another 2...Its normal

 

What made you think it had to do with the cat back?

that makes no sense at all....a car isn't like the human body..it doesn't experience fatigue after a period of time. All the car needs is fuel and air...the amount of time you drive has nothing to do with how much fuel or air your engine gets when you go WOT.

In your theory..when someone goes to the track to run their car...every successive run should be slower and slower...that doesn't happen.

 

my car sweats.. its a minute man

 

In theory it may be different...but when you actually think about it, driving to california then getting off the highway and nailing on the backroads...it will act different I may be wrong but watever

 

Sprint is that why you have nitrous to cool off the sweat?

 

Have you done a tune up on it before or recently? How many miles you have on the car?

i noticed the problem after i installed the cat back-- the car only has 16k on it

 

And what drug might you be taking?
