High-Flow Downpipes | High-performance driving, track use | Stainless Steel Construction (304/409 Grade) ▲ 1.5mm Wall Thickness (ISO 3801) ▲ Heat Shield (ASTM E84) ▲ CE Certified | ▲ Improved airflow (reduces backpressure) ▲ Durability (resists corrosion) Quieter than aftermarket alternatives | Higher cost than stock exhausts Louder than OEM systems (85 dB ▲ vs 75 dB stock) |
Stock Exhaust Systems | Daily driving, OEM fitment | Mild Steel Construction 1.2mm Wall Thickness (ISO 3801) No heat shielding Basic certification | Cost-effective (30% cheaper than high-flow) Quiet operation (75 dB) Warranty compatibility | Restricted airflow (▲ bottleneck for performance) Lower corrosion resistance (ASTM D543 ▲) |
Cat-Back Exhaust Systems | Full exhaust upgrades, aesthetic appeal | Stainless Steel (304 Grade) 1.8mm Wall Thickness ▲ Resonator removed ▲ Custom tips available | ▲ Enhanced sound quality (sporty tone) Lightweight design (reduces unsprung weight) | Higher cost ($500+) Complex installation (requires muffler replacement) |
Resonator Delete Pipes | Sporty sound, reduced backpressure | Stainless Steel (409 Grade) 1.5mm Wall Thickness ▲ No heat shielding Lightweight design | ▲ 15% airflow improvement (ISO 5167) Cost-effective upgrade ($150–$300) | Louder (▲ 10 dB increase) Risk of rattling at high RPMs |
Full Exhaust Systems | Maximum performance, complete replacement | Full Stainless Steel (304 Grade) 2.0mm Wall Thickness ▲ Heat Shield + Sound Deadening ▲ CE/ISO Certified | ▲ 25% power gain (SAE J1349) Longest lifespan (▲ 10+ years vs 5–7 years stock) | Most expensive ($800–$1,500) Heavy (adds 10–15 lbs) |
Turbo-Back Exhaust Systems | Turbocharged engines, performance tuning | High-Grade Stainless Steel (316L) 1.8mm Wall Thickness ▲ Heat Shield (ASTM E84) Flow-optimized design | ▲ Optimized for turbocharged engines (reduces lag) Lightweight (▲ 20% thinner than OEM) | Cost-prohibitive for daily drivers May void emissions compliance |
