I am changing my cat back system as the current one has way too much drone pretty much all the way through the revs (although as always, vtec sounds incredible). I don't have a fortune to spend so I am looking at the DC sports cat back system and the Skunk2 mega power 60mm system. I know it's only the cat back so won't make much difference (if any) in power, but is there any difference between the systems? Anyone have experience of both form a power/sound perspective? Thanks.
