I just in the past few weeks ordered a new front exhaust pipe ($334) because the whole thing was rotted out near the flex pipe so I decided to just buy a new one instead of messing around with the crapy one i had. This is the part I bought, a nice new magnaflow high-flow cat.
This is the real life picture of the crapy piece I took out (after cheap repair)
Then this is both the old one and the new one
After I installed the new pipe my car now has so much more power (from no more big hole) and its now real quiet. Im very happy wit the results
