Eloy, we're hardly keeping up with you. Please do take it easy on launching new products / sale for some time. This is absolutely a sweet offer I can't refuse! If you release 1 more new product / sale for this month, I'm going to file for bankruptcy!

Please don't listen to me and keep releasing amazing innovative products even if I have to take a loan, there is no stopping me.

I was wondering, how are these different from other Aftermarket CATs. Are these the HI/Flow version and gives power throughout the powerband? I currently have headers, section 3 and section 2. With these Hi/Flow cats, will I lose low end TQ and Gain high end TQ or will gain on all ends of the spectrum. Thanks.

There are different manufacturers of aftermarket high flow cats. They have different cell counts, body size, etc. These ones are some of the highest flowing on the market, with sufficiently small flow restriction for way bigger engines than the M5. Compared to the stock cats, you should gain throughout the spectrum, though (with all sec 1), the gain should be relatively small.

There will be a relatively small increase in volume going from the stock section 1 to high flow cat equipped aftermarket section 1's, nowhere near what a section 2 or section 3 does.

As with all things, depends on your current mods, and what dyno it's measured on. We'd expect only about 2hp peak (and around 3-4 in the mid range) from an otherwise stock car, on a very very conservative DynoDynamics dyno. With more mods, you should get a few more. With a Mustang Dyno, it'll read a few more than that, and of course, even higher with a DynoJet. The truth of the matter is, in this application, with all of the aftermarket high flow metal-matrix cat equipped mandrel bent section 1's, this is what you'll get, even with the MSRP: $5089.79 SuperSprint version. Claimed power may vary, of course.
