And Im quite disapointed.... When I hollowed my cat, it gave me a very raspy exhaust sound and improved performance. With emmisions coming up very soon, I decided to buy the hi flo, and hopefully benefit from better flo and still pass emmisions. Welp, not only is the raspy annoying sound still there!, but My performance is noticibly reduced. Im quite frustrated with the so-called quality of high flow catalitics that Im gonna buy a test pipe right after my emmisions. I dont think I would have minded so much IF it actually improved my sound... but it didnt...
Comments??

hmm

I cant even rememeber what the brand is, but they told me that it should be 33% higher flo then stock. but I mean compared to a hollow cat.. the difference is huge!!! I want a test pipe now, after tasting the powre of a hollow cat, I dont wanna go back to a hiflo or a stock cat

once you get your test pipe you can probably sell that thing real quick at probetalk, as someone always wants a hi-flow cat.
