install a corsa exhaust

Finally, I bought the Corsa at http://4wheelonline.com. I like the sound of the Magnaflow on trucks but people here said that it will just sound like stock when installed on a GTO. Just looking for some feedback regarding the Corsa. What gain should I expect using this exhaust? Also, is upgrading my intake a good idea after doing the exhaust? Thanks for any inputs.

I honestly dont think a cat back will give you much power, but trust me you made a great decision by going with corsa. It sounds so goooooooodd. I also think anyone would recommend the Svede OTRCAI

count on it to sound different...don't count on any performance gain that you can feel...good luck with your choice.

Yeah, until you get long tube headers and a tune you'll only hear a difference. With just the headers and tune I went from around 325 rwhp to 375 and could feel it. Have listened to Corsas on YouTube and they do sound good.

This is my car with long tubes and Magnaflows for reference. It sounds the same (to me) as before I had all the work done, which I liked in the first place except for some drone below 2000 rpm.

I'm sure you're gonna love that Corsa exhaust.
