Did my latest MOD, Next ear plugs or loud stereo!

[ElDiablo Viper]

I did it! I took the CAT’s off and have Corsa. The car sounds like a true race car. At about 2k-2.7K is very loud so I have to step on it to pass 3K. I was going to install Roe’s free flow but decided at the last second to rip it out. My ears are still ringing from the Corsa music. I will dyno the car next week to see if I got more power.

I ran the Corsa for 3 months w/o cats and it's really not that loud. In fact it was quieter than Belanger cat back WITH hi-flow cats. I also ran a 4" round Dynomax muffler where the cats normally go, it knocks down the sound a tad but still leaves that great popping sound upon deceleration.
