H3 Corsa cat back, Corsa gave incorrect info to Autoanything,
have high flow stainless header and high flow cat forward system with Magnaflow cat back which was rusting, ran very strong and decided to try the Corsa 3 in. cat back system for more flow and lower tones, It arrived an the whole system is only 2.5 in. and not 3 in. as advertised, I phoned Corsa and was told to run it that the smaller tubing flows better, after a week the power is noticeably down on the grade i drive daily, have to drop a gear now, I dont fault Autoanything ,hope for sum help
Couldn't be happier !
I purchased the single side swept system about a month ago, I purchased this with the Black Metal Mulisha tip put the system on my h3 as soon as it arrived, installation was pretty easy but I recommended having an extra set of hands I installed it on my own took me about 3 hrs, removing the oem system was the hardest part, as for sound its not too loud but it gives it a nice aggressive exhaust note and dont worry it sounds nice, I was a bit worried that it would sound like a Honda Civic ......
