Jp Performance 3" Cat-Back Dyno Results

[EricSol]

I was on the dyno last night and made 13 more hp at redline with NO LOSS and even a slight gain at low rpm. I had a custom 2 1/2" catback before with the Jp Headers. The 3" system has 2 resonators and a Stainless Magnaflow and is quieter then any of the aftermarket catbacks I have heard with the Jp Headers. It will be removed from my car today and jigged so it can go into production next week.

Jp will also be releasing 2 different Y-Pipes next week, for cars with and without pre-cats. There will be package deals on the Y's with the catback and on the Headers with the catback. For all previous Header customers Jp will have special pricing on the 3" Catback.

This makes sense. For the kind of horsepower (300+ at the crank) you are running, you should need a 3" exhaust if it is single. As long as the primaries on your headers are smaller diameter to encourage scavanging, you want max flow after that.

So what HP are you up to now?

The Dynojet I have been using isn't as liberal as Area51's so my best is a 267fwhp.
