Stainless Steel Centre Spool Monster Stack - 48"

The Exhaust Stack That Actually Handles Real Work

This 48-inch (1220mm) stainless steel centre spool isn’t your average exhaust stack. Built with an 8-inch outer diameter, it’s sized exactly right for heavy-duty diesel applications where exhaust flow matters. The 8-inch diameter is optimal for semi truck applications, helping to reduce back pressure and enhance engine performance —which means your engine breathes easier and runs better.

The Taperloc outlet design gives you a secure, leak-free connection that stays tight even when your truck’s doing the hard yards. No rattles, no gaps, just a solid fit that works. The plain inlet at 48 inches makes installation straightforward on standard semi configurations, whether you’re replacing a worn-out stack or upgrading from something that’s seen better days.
