i jacked up my car the other day and was looking at my exhaust. i noticed that the two headers come down and go into 1 pipe and then it comes through the cat and then splits intwo. one pipe goes through a muffler and the other does not. in other words if i gutted my cat, one of my pipe would be just straight pipe coming from the bloack. is that normal?

 

It's normal for a Borla exhaust system. 5SIZ has the same thing on his car.

 

If memory serves, you can regulate the flow through the strait pipe. I think it is normally closed off, but you can uncork it or partially restrict it as you see fit. Check out the borla site

 

i think that cat back kit was supposed to come with 4 metal plates for the passenger side pipe. one made it completely sealed off, another opened it up a little, then there is one that is fully opened...

look in this pic, and you will see the metal plates...

 

is there anyway i can get rid off those metal plates?, i predict that they are decresing airflow and loudness.

 

that is the idea behind the plates. In some states it is illegal to have anything to flow without a muffler, thus the "off road" plates. It should be bolted on there, you just unbolt it and take out the plate that is in there.

we have like no emissiions here, we don't need muffs or cats, don't matter...
