I hear ya. The corsa was loud.

I may be running late on tuesday, but will show. I have been thinking of doing the same thing with the exhaust as I have a cutout when I want loud.

Where did you get the muffler? I've had my eye out for one of these for a while but they seem to be pretty hard to find now.

that looks and sound like either a lm1 or 2 not a dual/dual. It might have dual dual tips on it but that is pretty much where it ends.

Is it just me or could you basically just build a dual dual system from their clearance parts?

They have
-Muffler
-Passenger and Drivers side tail pipes
-The hangers required

The only thing I'm not sure of is intermediate pipe they have listed, is it 3 pieces or just the longer piece that connects to the y-pipe..

I was thinking the same thing but I noticed it only has a 2 1/2" inlet. I think the LS1 version had a 3" inlet but not positive. My mid pipe is 3" and I wouldn't want to step it down to 2 1/2".

Can you please provide a link for this muffler? The only one I can find has the2 1/2" inlet. I would give this a try if I could get the muffler. My car is way to loud.

I have that catback and with LT's/ORY I could barely notice a change in sound. Will it get much louder with a cam? I am in the process of ordering a custom Patrick G cam from Thunder. I have a cutout at as well for added sounds when I need it though. It is nice right now to go from insanely loud to extremely quiet.

I've got the same setup. I did remove the ring of silence however and they did make a difference in volume. im in the process of buying a cutout now however for the real loud sound. the dual/dual is all 3'' piping, someone above was wondering

wow i was on slp's site last week and they had it, guess they sold out of all of them. i did find a powerflo muffler on ebay. it says it's the original d/d muffler but it's not. if you look in the pic you can see through the muffler(d/d had an extra baffle there).
