Good Muffler. Well made. Doesn't break the bank. My Z28 sound is now similar to stock until I punch it to get the aggressive note. No annoying highway speed drone to interfere with my music. I expect this stainless steel muffler to last a long time. No weld install with the correct clamps and tail pipes.

I have used universal Magnaflow mufflers for years on over 10 different cars. This in was on a Volvo C30 5cyl turbo. Very mild upgrade. Noticeable over stock but will not turn any heads. I also deleted the mid pipe resonator. I hope it gets a little louder once I replace it with a catless downpipe. It has gotten about maybe 3-5 louder after a few days of driving after install. I don't really like super loud straight pipe cars.. but this application could have been a touch louder and more aggressive for sure. Some OEM sports cars come with a louder exhaust.
