Our exhaust development began the first week the Fiat124 was available. Unlike a lot of competitors just welding up stuff that looks and sounds good....we ALSO want the best horsepower and torque results too. That means we started with testing and answering questions such as how much gain we can get with just a muffler delete, and then how much more with highflow midpipe, and then how much more with highflow downpipe, what pipe size this application of this motor wants, etc. Dyno work posted in some of the product descriptions for complete combos below.
Brian's Fiat 124 Exhaust Guide Summary. The complete combo systems below are all three pieces from the converter (Highflow muffler delete, Highflow 2.5 inch midpipe and the Highflow Crosspipe). Soon we will have separate highflow 5 inch body converter for those in non-CARB states. If you care about performance, our 2.5 inch big flow Crosspipes are KEY to getting the turbo more responsive and you want a complete 2.5 system that carries that flow all the way out the back. Competitors are selling muffler deletes with stock size pipe that will not flow as well, will not equip you for the best results with tune and other upgrades like a bigger turbo, etc. Note that only our Dual Tip choice is unique in the market for being ADJUSTABLE for sound using included baffles and optional packed baffles.
We strongly recommed our OpenFlash Tablet Tune with our full exhausts, it dials the fuel delivery to best match the bigger 2.5 inches of flow for the long term safety of your converter and the maximum performance gains. The OpenFlash Tablet is currently the ONLY tune we certify as tested compliant with our exhaust system, will soon test Tork tune with our system. We have customers running various EC tunes and telling us they work great with our system, but we have not ourselves had opportunity to check EC tunes for A/F accuracy with our bigger than stock 2.5 inch pipe systems.
