Did you just go to a exhaust shop and buy a couple pieces of pipe and have them pre flare it, and what type of clamp to I need to pick up? How large do I need to tell them to flare it to?
Thanks
Yes, that's exactly what I did. Cut the cat leaving yourself as much of the curved flex pipe as possible (the straight part of it), and measure the distance from there to the exhaust (leaving yourself a couple of inches to slide the flared part over the flexpipe). Autozone sells a precut 18" piece, but that was too short for stock applications.
Definitely use a u-clamp, and not flat band clamp. Mine leaked as well with the flat band clamp. I also bought one of the muffler mending kits (the kind that you dip "bandages" in water, which hardens into a cast) and wrapped the joints. No leaks.
I have the Corsa, and I like the sound. I thought the sills were still too hot after using hi-flows.
