my car used to be so loud it wasnt even funny. now i can barely hear the damn exhaust. i have a Mindtrain header, Bonez cat, and Apexi Dunk single with 2.5" piping from the cat back. i noticed this only recently when i started having cooling probs cause of a bad coolant filler cap, the car over heated a couple times, i got everything cooling wise fixed and now i am having vacuum line probs with it now, which is getting fixed this weekend with hose techniques SVH. does anyone know why my car is not loud any more?? please help.

 

Did you lose a lot of power? Your car or muffler or both are probably clogged.

 

i agree with gene there. i think that your muffler or somwhere along the exhaust pipes got cloged.

 

also your cat could be cloged get a test pipe and check it out

 

maybe your cat sucked up something nasty and it's stuck?

 

Maybe you've gone deaf from all that loud azz rotary exhaust. Have you noticed that your gf doesn't annoy you as much as before? It could be related...

 

Funny ScrapFC, you beat me to that line...

 

you might've gotten used to it and it just doesn't seem as loud, it happened to me

 

Hows your air filter? If that is gunked up its not going to suck in the same amount of air as before. But ya you might be getting used to it.

 

all of the header and high flow cat and exhaust are relatively new about 1 year 6 months old. has anyone ever heard of a rotary going quiet before?

 

sometimes my car seems to have a different tone and volume to it. its kind of weird.

you still have your airpump hooked up for that cat, right?

 

yeah the split air pipe is still conected, and i do still have air pump on there. i dont get it it used to be so damn loud, and now its not.

 

lol scrapfc....I know I'm deaf cuz of my open exhaust, and i can name several people who are deaf because of me( heh..that's what they get for messing with me) I had a carful of guys hold their ears cuz it was so damn loud.

 

Could this happen due to over heating the engine cause i had that happen to my car cause i had a faulty radiator cap and the temp gauge was all the at the top. but my car still idles fine and starts up good too.

 

come on help me out!!!

 

I wouldn't complain or question It...I'd be very greatful. Especially If you heard my setup. Loud!!!

 

Hmm...My car got quiet for a while and then I heard a "POP!" and it suddenly got louder. I took the exhaust of and found that the first pre-cat had clogged, melted and then sucked through, making a mess on the seond pre-cat.
I'd pull that cat and see if it's clean.
