I'm not sure this is for me...but I thought I'd share for those of you looking forward to this product release. It didn't have anything about performance gains, although I'm sure that is the point. Given the price point anyway I'm making the assumption this isn't just about exhaust tone.

It looks like they only offer resonator changes and secondary cat delete. Seems really expensive for straight section 1 and section 2. That would put Dinan's full exhaust system at around $5200 not installed. Wow.

Bummer on the price point. I had plans on getting this but I'm fairly
certain I'll need to swap out my Evosport headers for RPi headers
due to the loudness. I'm might have to rethink things now.
+1...that's what i'm planning to do too

The price is what caught my attention, but I'm going to go out on a limb here and think there has to be some performance gain that just isn't spelled out yet. I can't imagine they are simply taking a few measurements and then throwing in a couple of $20 pieces of exhaust tubing and charging $2,000 for it. Otherwise this thing would have been out 2 years ago.

There has to be some R&D you are paying for behind this whole thing with how this all works with back pressure, air flow sensors, ECUs, etc.

That said, the ASR system would seem like a bargain compared to this complete setup.

Nice to have choices and the competition among tuners only makes what is available to us that much better.

So a couple of questions then...

Are the gains inclusive of the mufflers, or in addition to (since they are required)? Because they report those exact same gains for the mufflers alone.

Might this be similar to what ASR reported, where the max gains were not as notable as the increase in low end performance?

My initial thought is that the gains are on top of the exhaust. We'll
need someone like 550Chris to verify. I think we've seen dynos that
show that a midsection replacement usually results in this type of
gain.

My personal opinion about section 1-2-3 replacements is it's more for
bark rather than bite. For additional bite get headers.

U want to be a guinea pig, Marshall:applause::applause::applause:

Keep in mind that some combination can loss power as well, but I'm sure Dinan did extensive testing before release the product, at least with their muffler:blink:

When you plan to get RPI headers? We need, hmmm....:3:...:cheers:

My question about all of this is why are the gains so low for the Dinan High Flow Middle Exhaust? Also the Dinan "Free Flow Rear Mufflers" are required in addition to the $2,799 middle exhaust.
This just doesn't seem to compare to the Stage II Engine Upgrade offered by Turner Motorsports. Which is a front pre-cat delete, replacement of rear cats with an ecu tune. I also like that they can
install the Stage II and add euro launch control for a couple thousand extra in the same sitting. I'm wondering if anyone has had any experience with them or this modification? :confused:
