I have an 05 sedan with coupe mid, hr y pipe, and kinetix hfc. I have this hfc hiss which is normal. But I also have that annoying under load low rpm metallic rattle. I want to replace my oem muffler with a vibrant stealth series..flat black.

Looks like:

Anybody used this muffler on a sedan before? I see most people use magnaflow and hks. I dont like the bling bling look

 

sounds good on this maxima

 

Unfortunately, it's a hit or miss on if that muffler will help your problem or not. I would say it probably won't. I think you'll have to go with an aftermarket exhaust to fix your problem, or go back to stock cats.

 

I like the looks but I doubt it's going to do much to help your situation. If anything, it will probably make the exhaust and metallic sound worse because it's a higher flow muffler. You might want to consider picking up an 03/04 midpipe with the 2 times larger resonator. It doesn't hurt performance, but it will reduce exhaust noise and surpress some of the metallic sound.

 

a 24" branch resonator on ur middy should help
