when i first turn on my car in the morning...you can barely even hear my exhaust when im driving...but when the engine warms up, my exhaust gets louder and louder.....is that normal?

 

You need some speed holes in your hood.

 

what the hell are speed holes?

 

Don't you watch the Simpsons???

 

yea....but that still doesnt help me out

 

Do you have a stock exhaust system or modified? Check for any loose joints that get seperated when the car is warmed up? I have never heard symptoms like this one before.

all perf. mufflers do that!! on my friends GST hes got a dual tipped 5" muffler, its extremely loud but only after the car warms up!! my dynomax only gets loud after the car warms up too, it natural, nothing wrong!!

 

I have a ractive muffler too and mine always has a grunt to it. I took of my cat though so that could be the difference between the two. I like how the mufflers sound though. It's the best one I've had on it and they are quite cheap.

 

Would you rather have your car sounding like a civic with an Apexi dunk??

 

Speed holes...simpsons are great (homer hitting his car w/pike)

 

i would probably say it has something to do with the cat being cold causing it to be quite.
ive noticed on my other car that has a apexi N1 exhaust in the morning it kind has a higher pitch to it but as soon as it warms up it gets nice and deep.
on the other hand the N1 is a loud exhaust system no matter what car you put it on.
unless turbo or supercharged.
