Yes, but the weight reduction alone is welcome. If you get the ceramics, the underhood temps are also reduced. Mine is 100 degrees cooler under the hood than anyone else with the coated ones. Weight and lower temps. Don't care as much about a performance advantage.
valid points, but again, are you that worried about weight with a driver, m cars have ci 6 pack manifolds, lol, you ever pick one of them up off the ground lol, or a shelf over your head...
I agree, as I said in previous post, racing, or after every ounce, headers are the guys, but for 90% of the rest of us, ci will suit us better...
If I am racing, I wont be doing it in a 25foot long chrysler, lol I would do a tube framed small/medium pickup truck. A friend of mine has a dakota body, aluminum bed (just the sides, no actual bed in there, its paper thin), 2 seats in it, around 900hp, link , tubbed, power glide 2 spd, etc etc etc , but it is streetable, has 2 seats in it, lights, a vin number, etc etc etc.. he drives it to work sometimes, lol (its powered by a big blown chevy though..)... He has the coolest rear end, I belive its a ford 9", he can swap gear sets and go from 4.10 or 11 to 5 something, not sure the specifics, but he swaps that gear seat and the tires in like an hour... he can drive the truck to the track, with the jack, wheels, gears, tools, etc in the bed, change them at the track, and race all day, swap it all back and drive home... The truck is capable of running much faster than he runs, but he dials it for aspecific time and runs that way, he said its just as fun and doesnt break anything (as often), so I guess his motto would be "you want to run 10.0's, build a 9.40 car and run 10.0s.......
