Thread: Quiet as stock aftermarket muffler.

Which one exactly? Link?

LOL how big is your tailpiece? Maybe bolt in one of those adjustable tip ends that sell with the Jap Style rear muflers - just to pass the test. Then unbolt it afterwards...

Here is the muffler that I currently have. I have the 2.5" JGY exhaust on my car but the 2.25" flowmaster was the same exact size as the JGY 2.5" piping.....go figure.

I have a couple of tricks up my sleeve that I am going to try first. Right now I currently do not have a tailpipe on the car.....just the flowmaster at the end of the line. I think I am going to try to rig up a temporary 1" diameter tailpipe and see how that goes. I also called a local muffler shop and they said that they would help my out. Basically what I hope to do is find a stock muffler from another vehicle that will fit under my car with a 2.5ish" inlet and mount it up.

Yeah it reduces the noise and you are right it does causes a droning noise at certain speeds on the NA car.

Part # WLK-17733

Sorry Ben for some reason I can't post up the link but with that part number you can see which one it is.

As an update I finally passed. I rigged up a 1" tailpipe to the back of the magnaflow. I got about 4" sticking into the flowmaster and about 4" sticking out of it. It made a world of a difference, the car sounds pretty much stock. I think many of our exhausts are so loud is becasue we really don't have any room for a tailpipe if we mount the muffler in its stock location. As an excersise I might try to run a 90 degree bend out the back of the flowmaster then run a tailpipe under the car parallel to the rear bumper and dump the tail pipe under the driver's side rear, opposite the stock location. A good 4 foot of 2.5" tailpipe should quiet down the exhaust significantly over no tailpipe at all.
