2001 blown ZO6 modified Torch Red
I've been working on sound improvement for my blown 2001 ZO6 which now includes long tube headers, Random Tech cats and Corsa Sport mufflers. All is great except the Corsa's are too loud. No drone but loud on acceleration. I'do care about back pressure considering the engine mods and I'm currently thinking on modifying the stock Titanium mufflers and reinstalling them. I can't just keep purchasing replacements aftermarket cat back systems given the $$$ involved.
Any experience out there in computer land on something related?
