Show original supplier description
The STILLEN Axle Back Exhaust System is engineered for the 2019-2023 Nissan Altima AWD models equipped with the 2.5L engine. Installation is straightforward with its bolt-on design, complementing the factory exhaust cutout. The system offers a balance between enhanced sound and a luxurious, quiet cabin feel, appealing to drivers who seek both performance and comfort. The polished stainless steel finish delivers an aggressive look that matches the improved exhaust note, contributing to the overall aesthetic appeal of the vehicle. Customer feedback indicates a direct fit and easy installation for AWD models, with satisfaction regarding sound quality and overall craftsmanship. However, some users have noted issues with the hardware for the tips, suggesting the need for potential welding or modification in some cases. Additionally, one user reported that the system is only flange-compatible with AWD models, requiring modifications for FWD applications, and experienced bolts snapping during tip tightening, necessitating welding.
