I was just checking up under my car to see where the muffler was located. It's right up under the passenger side seat. And after that there's no cat on it and the pipe is cut halfway under the car. Now I'm going to replace the whatever under with a magnaflow 12265 muffler. My question is should I go with a regular cat or get a high flow. I'm not sure how much it'll effect my performance if I do put one on.

 

It should be behind the rear axle.

 

That's what I figure. I didn't put the exhaust like that. It was there when I bought the car.

 

I have crinklepipe for an exhaust

If I were to have to replace it, I would run a single 3" system with the muffler in the factory location.

 

Well I just ordered a magnaflow 12265 muffler. Just my question now is should I go with a high flow cat or just a regular cat.
