Sound difference between UR 3" cat delete and HF cat?
I've heard the power difference between the 2 are small, but what about the sound levels? I have a 3" RMR catback & downpipe on my car, and dont want things to get too much louder...
Thanks, Ben

I have both UR hf cat and Helix test pipe. The test pipe make the exhaust louder than the hf cat but it's a very good performance sound. The level of the sound is also depend on the exhaust that you're using (I have AVO turbo-back). I'm only use the test pipe when I go to drag or track. It let me use 110 gas which is leaded gas.

i have the full UR turboback w/ testpipe and it sounds like a bat out of hell,not nice or pretty either its rough and muscle,when running cat it was much quieter and it creates a sputter at idle(the TP)any officer whos been trained will recognize that sputter sound

. So the sound with the UR hf cat is significantly quieter than with the tp? I have the rmr cat back which is pretty loud, and i don't want things to get out of control 
. Thanks again for all the input.
