Thank you. You have rated this product.

Imagine a perfect drive in your Fiat 124 that includes burbling dual tips or quad pipes! Add FUN to YOUR Fiat 124 with our Fiat 124 Exhaust Combo. Complete Plug and Play 200 Ft/Lbs of Torque Stainless Exhaust System! Includes 2.5 Inch crosspipe (2.25 on automatic models), 2.5 Inch resonated or non-resonated midpipe, 2.5 inch highflow muffler replacement.

Note: We strongly suggest most folks order a resonated midpipe. The sound of the complete exhaust with a resonated midpipe is ideal for your daily driver and will keep sound at reasonable level. Yes, this is a CARB legal 'cat-back' item because it bolts to rear of stock converter. This is the path to 200 Ft/lbs of Torque per our dyno graphs in our forum Fiat thread!

Like all RoadsterSport exhausts this system is All POLISHED 304 Grade Stainless Steel construction and LIFETIME warranty. It also features full 2.5" mandrel bent exhaust from the cat. Automatic transmission compatible crosspipe has 2.25" piping to clear the transmission. . Installation of each part can be found in their individual product descriptions. 

Hear the fun!

DYNO GRAPHS! Result is new HIGH For Fiat 124, 160 HP at the wheels, 200 FT/LBS Torque pushing you back in the seat! Felt good at the first Fiat 124 SCCA appearance so figured it was time to dyno the setup, and now I see why it felt good, that's some healthy torque! This is still stock tune, which means this is CARB compliant power legal in all States!

Lowest Line is Best STOCK Pull. Middle Line is Best Pull with just highflow Muffler Upgrade. Highest Line is Best Pull Full Crosspipe, Midpipe, Muffler...Peak HP up 'only' about 15hp but notice total area under the torque curve is massively better, up over 30 Ft/lbs of torque through much of the middle rpm range, peak gains over 50 Ft/lbs at the low end thanks to faster spool for the turbo.
