[EDFHOBBIES]

1 car with headers and stock suitcase the other with headers and Borla ATAK.. neither have cats..

The borla is quieter in 6 gear just cruising it doesn't matter 1800 2200 or 3000 rpm if your not on the pedal more than 1/4 the borla is very nice and quiet in the cabin.. but, once you lay in to it, its extremely loud, cold starts are very loud.. but all can be changed with the valves if its not your cup of tea. But that doesn't mean the car behind you doesn't hear ya cuz when I follow my wife its loud! but inside you would never notice it really..

Stock w headers....I notice going up to Cfest at 2100 rpms about 81 mphs in 6th I had a vibration noise.. I thought it might be the tires so I kept up the speed and put in the clutch and it went away.. I also kicked the cruise up to 85 in the same gear and went to 5th at 81 the noise went away.. so not sure if its the headers orthe stock setup from the off road pipes back. I know it was very bothersome..

I know on the borla setup No weird stuff ever.. I'm holding out for the Carbon tips Borla Atak for the ZL1 vs making a SS fit..

I helped a friend install the Corsa we ran it with no muffles at all that sounded pretty good actually very similar to the Corsa he has just not as deep.. He later put on the Borla Xpipe and did a video of it with phastek the Blue Zl1 1LE..

I like the Corsa to just seemed like a lot for Axle back and no valves..

I have had 2 good friends complain of drone maybe something similar to what I'm experiencing with headers and stock muffler on their Complete Stainless Works setup.. but that was when the Zl1 1st came out maybe its fixed now.. I know its not as loud as the Corsa and Borla they complained about that to..

Flow master at idle sounds like boat exhaust bobbing up and down out of water to me just my opinion they seem ok wide open though..

I can't see how Borla sounds to exotic.. nothing will sound exotic with such long rods and big stroke in our motors that rev to 6500.


your right it seemed like the SS w blower amplified my ATAK system lol..
