bought my car about 3 or 4 months ago .. maybe more, i dont remember. ha. it has a dual exhaust , i think , i saw some posts in this section about true dual exhausts? the car has a nice rumbling sound. when i start my car at night , to let it warm up before i drive it, the exhaust pipe on the driver side smokes ALOT more then the passenger side.. the passenger side barely smokes at all. but if you put your hand over the pipe you can feel the fumes. the exhaust is pretty new , replaced within like 6 or 7 months .. still normal colored, mostly

he told me the rumbling is for sound, not performance. i never asked him what he did to it to do that either, stupid me me and my cousin looked under the car as good as we could at the muffler , didnt find any wholes, but we couldnt see the side towards the front of the car.. ground effects were making it so we couldnt move , and too lazy to jack it up.

im prolly missing some important info , if i remember what all i missed ill post it again ... sorry if im missing anything, just let me know what info , and ill try to get it answered .. and when i rev the engine up, it makes a weird sound when the RPMs are going down, and the RPMs take a little while to go down..

whats the best way to get a sound clip of the car? my dad has a digital camera that takes 12 second video clips in quicktime format... i could get a video shot of the RPMs going down slow and with the sound. just let me know if there is an easier way to do it.

the car is a 90 RS 3.1 MPI

thanks.

 

I use my laptop for sound clips. Most likely you don't have true duals, probably just dual pipes out the back. Look under the back of the car at the muffler, are there 2 pipes coming out of it? That weird sound is probably just small backfires that are normal with low backpressure.

 

the muffler has 2 pipes on one side , and one on the other...
one going in , 2 coming out , but i think there is only one muffler


i think its like this

haha like the pic?

 

One muffler= single exhaust.

The 2 on one side, one pipe is coming from the I-Pipe and the other leads out the back, plus the other that leads out the back.

 

so its just made to look like dual exhaust? is that why only a little bit of exhaust comes out the passenger side pipe?

 

That would be why yes.
