noise with gutted cat

So I have the cat gutted...anyone agree that since the cat's body material is thin metal, that it sounds really like tin with your head under the car? I would think a midpipe instead would be a better choice to get rid of that.

Taking the precat is enough deletion. Why did you take the main cat out? What a povo mod.

You get to pollute the environment, smell bad and sound like crap for an extra 5kws, not worth it in my opinion. Put a sports high flow cat in.

I have the resonated M/P from RX7store. It sounds great, girls love the smell, and I get to pollute the environment! There's NO downside!

Keep in mind that the stock piping is 2.5" where as an aftermarket midpipe is going to be 3".

Good point. I am not running the airpump, but I have seen several examples of aftermarket high flow cats being used without the airpump. I may just go that route.
