I actually ordered some not too long back. I've used them once and they worked great as you said. Ditched the thought of adding anything more permanent to the car and it filled the void when ZL-1 dropped the ball on their offering / my order...and much cheaper too!
I just asked Remark on IG if there are plans for a Ti system. Didn’t think to ask the non-blued question but I’m with you that I would prefer raw tips.
This definitely has my interest! While I’ve already been drooling on Remark’s other offerings, they sneak this one in. Anyone know if there is a sound file that we can listen to? Looked on Remark’s website hoping they posted one but looks like it’s not posted.
I can’t answer your specific question but, I recently saw that Spoon USA offered a complete engine. Might be higher priced than a stock engine but, an option at least.
