| | LS4 exhaust stock vs. aftermarket
Is it just me or does the stock exhause sound better than these SLPs and duramax cat back kits... I really want a better breathing exhaust but all these YouTube guys with their new exhaust seems like it doesn't sound good at all.. maybe its the video not doing them justice..
Anyone know of any that sound mean!! Better than stock.. possibly that they heard in person.. or video but I want the link hahaha
