This Spintech side exit exhaust is the ultimate way to make your GTO look hot and sound great! Start by increasing the tubing diameter from the factory 2” to a mandrel bent 3” tubing, then add Spintech's famous mufflers, and you have one awesome system. This design sounds incredible when mashing the accelerator but provides a mellow tone while cruising with almost no interior resonance. This system is features DSV tips, which are a dual split oval tip, set-up that has two tips on each side. (2.5" system pictured). We recommend this system for cars pushing over 475 RWHP, on cars with lesser power, the loss of back pressure may hurt performance.

While we carry inventory, some Spintech systems are built to order, so please allow 7-14 days for shipment.
