Yes I’m aware of that. I’m asking about the IPE straight pipes which apparently have a specific design and minicat in them before the sensor. I’m asking specifically about these IPE pipes.
2013 458 coupe with Headers, catless test pipes and s-line x-pipe with a tune on mine. The car sounds like Pearl Harbor. Daily driver status….meh
All I want is better control of the valves to get rid of the on/off at 2800 rpm and smoother off throttle response in lower gears. I’m leaning to a custom tune from OFT with the burbles as a bonus. Somewhere down the road I might do something with the exhaust but right now I want to address the two biggest issues I have with the car.
I’m working with Shiv from OpenFlash for my otherwise stock 458. Going to do some back to back testing in May. Will post results.
