[ZR1] ZR1 muffler mod
#1
ZR1 muffler mod
Has anyone done the muffler mod on their zr1 here? I know a couple guys that have done it on zo6s but I havent seen any videos or heard of anyone doing it on zr1s. I'm not sure if htey are the same mufflers or not.
I am looking to do a M2W with the muffler mod if possible. I'd like to hear a video of what they sound like though first.
Thanks,
Greg

The internal pipe inside the muffler that routes to the exhaust tip with the valve and the flap that opens and closes is perforated on the z06 and it is not on the zr1 or later model 2011 and up z06;s. The muffler mod is wrapping that perforated pipe with sheet metal and clamping it or welding it to the peforated pipe.
This is all speculation as no-one on the forum has reported cutting into zr1 or post 2011 z06 mufflers to see what they look like on the inside

I think the Zr1 already had the muffler Mod on it done from the factory.

That's what I have, and the owner Ben is the best person I've ever dealt with bar none. Very kind, cool and helpful...I would make it a point to buy from Sunset Orange Creations.

My stock ZR1 in open mode is definitely louder than my stock Z06 was, and considering the LS9 is a much lower compression engine than the LS7, something is different to give the ZR1 the volume that it has.
Since many know what the inside of the Z06 cans look like, maybe someone can chime in that has had them both apart...

Hi friends !
❤
I Installed yesterday the x Pipe corsa on my zr1 of 2012 and GM did a good job with the 4 cat because almost no change in noise, the central console heats less so in the end I'm still happy! I'm still looking for a better sound ... I still do not know if the stock muffler are already mod or are there holes in the central part where there are valves. My garage asks me $ 600 to dismantle open solder and go up ... I think strongly to take directly a Borola ATAK or other if it exists even better thank you for your answers
