I just put on headers & de-cat pipe from a company which shall remain unnamed. I have a BWR s/c and Larini SE Euro style muffler.
I dynoed a few days ago and received WOEFULLY low numbers. Unfortunately I didn't dyno before with the stock system in place for comparison, but I will begin that process tomorrow.
Basically: The car is REALLY FREAKIN SLOW compared to before. It's so slow that I swear it's an NA car sometimes. Maybe a little more juice than NA. Even my lady friend noted, WITHOUT my provocation, the car felt much slower when I got on it and I struggled keeping up with my drive group today.
What could be the cause of this? Lack of back pressure? How does that work and why does it eat power? Is it with something that, with proper tuning, could actually gain power, or is the exhaust system just too damn big with or without tuning?
Stock set-up didn't sound as good, but it was very quick and ran properly.
