Nice, refined sound
This is a nice exhaust system, and definitely an improvement over stock. It's well made and the quad tips are a great aesthetic improvement. For those looking at a difference between this and a mid-muffler delete; what I can say is the mid-muffler delete is louder, at least INSIDE the car. You feel more growl and rasp with that, probably because the sound is just going up into the car instead of out. This system sounds BETTER than the mid-delete, though not necessarily any louder...from the inside. From outside rear, I think the Corsa system might actually be louder than the mid-delete. It definitely sounds better...more refined and healthy sounding. There definitely is no drone, and even with MDS, it sounds even and controlled. MDS always sounded lame and droned a lot, with the Corsa system you can barely tell it's activated. I used a 1/2" spacer (a notebook, lol) to maintain distance between the mids and the bracket, and ensured clearance between all the parts was maintained by fell/finger distance between heat shields and the rear suspension. The install went well overall - the biggest issue is the removal of the stock system. I recommend removing the 3 bolts holding the metal trim piece onto the valance and sliding the metal piece onto the tailpipe end to help get the stock pieces freed up. Otherwise, I never found a way to remove the stock system without a Sawzall. I also recommend leaving the plastic brackets intact that support the metal trim pieces, they provide support to the valance, and leave it less "floppy" as others have commented here and other sites. You just need to make sure the tips are centered and aligned. On that, the system is pretty dependent on fine-tuning. You can adjust quite a bit by sliding parts on the hangers, and will need to. The instructions are out of date - they show "tunnel mufflers" that are a lot longer in appearance than the current ones, and also show drain holes at the rear. The current ones are much shorter than those shown, and don't have drain holes. When I eventually got a hold of Corsa support, they told me there was a design change and I could drill into the mids if I wanted to. NAH. I recommend fitting the X pipe assembly as far forward as possible, and the mids as well. I mounted them serial number down and called it good. Then, the pipes and rear units can be adjusted. The way I did this was to center the tips and then tighten the mids-back according to that. I prefer the tips sticking out from the valance a bit, so I adjusted the pipes and rears accordingly. All that said - the install is pretty easy, just know your final adjustments will be based on how you fit it all together. All in all, it's a nice system that looks and sounds way better than stock, and I'm happy with the results over the mid-delete.
