I've seen this post before, but what I want to know is: What does it sound like?

 

My hi-flo cats went bad after 1 month,it sounds like a bunch of little metals ball dancing around inside your cat!

Just get under and knock on your Cats and you'll hear them answer.
Bassani told me I was the only one with bad Cats.... Thousands of Exhausts sold, never had a problem.

My Bassani's went bad after 4months. Could not get any response from them. Wacked them out and put it some cheap ones. Truck runs fine now.

bull****..soundz like Bassani has no customer service

The only complaint that I have heard is the Cats..the headers seem fine...i'll run long tubes...if I go through with it...

 

noelvm...have you talked to Randomtech, or know anyone running their cats? The dyno #'s look pretty good if the price isn't to steep for them. Wonder if they ever tested a "L" our exhaust is acceptable from the factory. Didn't that one mag say we only had 2% blockage?

 

I don't know anyone running them. price I was quoted was $225.00 EACH. Very expensive.
We need a rich ginny pig.
