The OP was running the Corsa extreme and complained about it being too loud.
I am running the Corsa sport which is exactly the same as the extreme except that the sport keeps the oem resonator.
BTW both system replaces the muffler and the tail pipes.
I suggested to the OP to reinstall the OEM resonator and doing so will make it less noisy. Why do you think they call it an extreme system? lol!
BTW ... I like my corsa sport. It has a nice cold start and is for the most part is quiet until you get on it. And even when you get on it it is not super loud.
This is just my opinion but don't mess with the down pipes as it involves messing with the cats. And also playing around with the down pipes by getting something more free flowing makes it loud as hell. And did I tell you they are a PITA to install.
AWE systems are nice in that you can do 1 piece at a time. I would go with the 2FG to start and add more pieces if you want more volume.
When I replaced my exhaust I weighed everything.
OEM muffler >> 39.9 pounds.
OEM tail pipes >> 20.4 (driver side) & 15.2 (passenger side) pounds
OEM total weight = 75.5 pounds
Corsa muffler >> 25.25 pounds
Corsa Tail pipes are total of 6 pieces (2 pieces per side and of course 2 enormous tips) >> 6.05, 7.6, 7.85, 9.7 and 3.55 x2 (tips)
Corsa Hardware >> 3.75 pounds
Total Corsa weight = 67.3 pounds
And AWE advertises a weight savings of 23.5 pounds just by going with the 2fg (muffler replacement) and with the 0FG (replacing everything downpipe back) you are saving 41 pounds.
I hope this helps you decide.
This is what makes the decision so difficult. I have been holding off on a resonator delete and going with a straight system, no X or H pipe, but trying to figure out the sound without buying everything and selling it all.
i am looking for ZERO drone and the least amount of Raspy, I really don’t want to change the whole system
Remove the resonator and keep the rest of the system stock?
Change the Down pipes ( I have to keep the cats) and keep or Chang the resonator?
Change just the muffler? And possibly get rid of the resonator?
So many options and some are costly and would end up in the classified section
I drive mostly in a small town and jump on to the highway/Parkway and 70-80 mph is where I’m at
thanks in advance
