Product Description
The Spec-D N1 catback is a full exhaust upgrade for 2005-2010 Scion tC owners who want to replace the restrictive factory system with a more aggressive single-exit setup. It uses 2.5-inch T304 stainless piping, a straight-through N1-style muffler, and a 4-inch tip that gives the rear of the first-generation tC a more purposeful look.
Choose the polished version for a clean traditional finish, or the burnt-tip version for the blue titanium-style look. Both options use the same vehicle-specific catback layout and include a removable silencer, so you have the option to take some edge out of the exhaust note when needed.
A Budget-Friendly Scion tC Exhaust Upgrade
If you are shopping for a cheap Scion tC exhaust, this is a full stainless catback option rather than a universal muffler or cosmetic tip. It is aimed at owners who want the N1 look, a louder sound, and a direct-fit system without spending at the level of a premium-brand exhaust. Keep expectations realistic: this is a loud, street-focused N1-style setup, not a quiet factory-like replacement.
Before You Order
This exhaust is designed only for the 2005-2010 Scion tC with the 2.4L engine. Exhaust volume can increase further when used with an aftermarket header or other exhaust modifications. Professional installation is recommended, and you should inspect the original exhaust hardware before beginning installation.
