when im in park and i revv my car slowly when it gets to about 4K its starts to rasp like a ****, and when im driving it does the same thing starts to rasp at around 4 to 5 K (rpm) is there anyway to fix it? what is the problem?

 

what kind of exhaust do you have, stock or aftermarket?

 

You most likely have a leak.

 

I used to get a raspy noise too when I put in my custom 2.25 exhaust. It sounded like a civic. I ended up buying two resonators from ebay to imitate they set up that Greddy has on their Catback and it did reduce the raspy noise a little bit. But what really helped was the Headers.

 

Damn 915Max, your car is hott!

 

wrd....ebays the ****t

 

its an aftermarket exhaust, i think its a megan exhaust i got it off e-bay i dont know if they still sell it or not, im thinking its a leak too but i need to jack up the car to find out. HMMMM

 

thanks

Sy0p-- I heard those exhaust naturally are raspy. I've never heard them but I was looking into getting one until I heard that. Ask around to see how else has your set up.

 

This is a common issue with most custom exhaust tail pipes. Go to the Exhaust samples and listen to them, most of them sound like this beside Ceasar's and one other guy's.
