Why do strait through mufflers sound bad when cold, then sound awesome when they warm up. I didn’t notice this when I had my flowpaths but with the maganpacks there is a big difference when they are cold, I would assume it would be the same for SLP and Borla Stingers.
They are very poppy (raspy) on hard acceleration for the first few minutes before they warm up and sound good. Once warm they scream and sound good through all RPMs.
mine sound a lot different when cold. i have Spintech mufflers, have no idea which model they were on the car when i bought it, and a Bassani O/R X. a lot raspier when cold, i like it a lot better when its raspy like that. hopefully will be switching to Borla mufflers when i get around to calling them up and harrassing them for stingers.
