Guess the HP

I just bought 2.125" TTI headers for my car to replace the 2" TTI headers that are on it. It was dyno'd with 2.125 fenderwell headers.

I'd love to see it pick up this kind of power when I swap these
That would be very interesting to actually know for sure.
I have a set of fender wells that I’ll use despite there tube length being to long for top end HP. The price was right and I’m not a track warrior. The extra torque on the street makes for a great fun feeling car. While the previously posted increases are a bit more than a good bit more. I don’t spend a lot of time up in the top of the rpm range. Street cars normally don’t.
