LOL, I just saw an ad on Utoob for aftermarket racing seats in "Genuine Signature PU Leather."
You know what PU stands for? Poly-urithane.
So, genuine signature pleather. Besides which, leather is an absolutely horrible material for racing seats. Even luxury racing seats, that's why we make them out of modern high strength polymers. (Unlike Polyurithane, which is. What's the word. Old? No, cheap. That's the word I was looking for.)
I guess if you put a genuine signature gold tone Omega on it, rice boys will buy anything. Shouldn't surprise me, when we're talking about a market that starts at the exhaust, and "Tunes" their engine from that, on the theory that you can get more air out of an engine than you put in.
Now, I don't want to get off on a rant here, but the reason why you don't start at the tailpipe is because to "Tune" it, you don't listen to the sound it makes.
You balance the Back-Pressure against the airflow in the exhaust, after you time the airflow rate, based on the intake valves, which are fed by the air filter, ram effect, and intercooler.
So, first you stick a chrome plated #10 can on your tail pipe, then you buy a high performance inter-cooler. Then, you like the sound it makes:
So then you get a new cam, chip, nitrous, rims, vinyl decals, and hot pants that match your girlfriend's bikini for her birthday.
Oh yeah, and Turbos. Automotive turbos use the exhaust to drive the intake, and compress it. (Intercoolers also compress air, by cooling it.)
How do you tune an exhaust? Turn it up to 11, and that's 1 more. So, it's louder, init?
I'm starting to wonder if they actually know anything about how to tune an engine. Of course, that's just my opinion, I could be wrong.
