Same thing re carbon. People buy because of perceived reputation that can differ vastly from reality. Carbon is another example. Indeed, I cannot think of the last time I saw an aftermarket real (i.e., not carbon cloth laminated on a substrate and clear coated) carbon part in the aftermarket that was truly excellent notwithstanding that many do look good on the outside.

Further, if I had to name the highest quality fabricators/welders in the country, I would have a hard time naming more than one. As to the piece of which you posted a picture, my advice would be to look elsewhere.
I don't think it's necessarily fair to tar all aftermarket exhaust manufactures with the same brush. Some aftermarket exhaust manufactures supply more than what you see online alone.

Also Im hoping they release more data on the superlight Inconel headers they have and their tune too as I most likely will want to get them too.
Sorry about that. I did get back to you via email but let me check if there's any obvious issues. We can do PayPal.

Really feeling the love reading this thread, thanks!

Without bashing anyones product I think its important to note why a lot of companies opt for a pie cut design and this is simply that the costs involved with creating bespoke bends in high quality titanium (important to note which titanium is being used here) are extremely high. Pie cuts can be purchased online for very reasonable cost and give fabricators pretty much free rein to create any number of exhaust designs without any set up cost.

The sound characteristics and therefore flow are heavily affected by one single poor weld, never mind 20+ throughout a curve. Some of these welds 'can' look ok on the outside but it's the part that you don't see which has such a dramatic effect on flow / performance / sound. The specific titanium that we use in our system has a particular 'ring' or resonance to it and this resonance is affected by length of pipe between welds. A pie cut welded bend will not resonate (or flow) in the same way that a formed bend will.

Creating a titanium bend with a consistent wall thickness is an art in itself. Another sideline for JCR is in the manufacture of titanium bends build to drawings. We sell to a large number of clients around the globe.

We recently had a company attempt to copy one of our distinctive exhaust designs. In doing this they failed to recognise that theres a lot more to our design that might initially meet the eye. Wall thickness of the titanium reducing as it transitions from cats to tips. Material spec. Pie cuts vs bends (as above). Specific overall lengths. Merge capacity. Pipe diameter transitions. The list goes on and on. All of this resulted in the customer contacting me again a couple of days ago and doing what he should have in the first place.

There's another company about to do the same thing. I guess this stuff happens!!

Alright guys I decided Im going with their superlight inconel race headers and the full titanium race pipe with them both Zircotec coated. I'm excited to go with this setup and I think i'm going to be vastly impressed with the performance and sound upgrade! Going to try to document the process too and dyno before and after.
