Deep sound 2000 LS1
Stock 2000 Z28 LS1 Auto. Muffler swap only. Factory tips and kept the cats. I was very happy with the deep throaty sound when I heard it. Definitely better than stock muffler. I would recommend if just doing light mods to your Gen 4 Camaro or TA.... 5 stars...

Great muffler for a Third Gen Camaro
This muffler sounds great on my 1992 Camaro. It has a deep tone that’s not too loud and definitely not too quiet.

Not the sound I want
Totally wish I bought some other kind for my trans am. The exhaust just rattles around and does not have that growl you want with a TA.

Good muffler
Disappointed it’s not as loud as advertised… I wasn’t liking for obnoxious or droning but hard to tell the difference from stock

Love the sound that comes out of my 1992 RS ...
Love the sound that comes out of my 1992 RS 25th anniversary edition Camaro when I installed this bad boy on it. I thought it was gonna be too loud but it is just right. Glad I went with flowmaster.

My 26 year old car still had the stock muffler on and developed a hole that made sort of a rumble. As the car is a stock collector I did not want a roar but a solid V8 sound. After researching production mufflers I was leaning towards the Flowmaster 40 remembering from the old days. Realizing I am 40+ years older thought better. I went with the 80 series because of 2 reasons, 1. slightly quieter, 2 the only configuration that goes onto a camaro with 3 inch pipe in and 2 -2 1/2 pipes out on 1 muffler same as the stock. This required no mods to my exhaust system. As performance goes it has a nice start up sound and a decent roar at 3000 rmp. When at cruising altitude 1500-2000 rpm its sound is quite enough to hear the sterio and conversation in the cockpit but still sounding good. If you are an owner of a Camaro and do not want to reconfigure your exhaust to a Bolara system I highly recomend the Flowmaster super 80 muffler. I had my friend and ownrer of Jerry's Muffler in Kelown BC install it and with the muffler under $350. Better than $2000 for other systems.
