Uh, 90 is bad considering all the others are 150 (or very close).Indicates possibly a cracked head (between valves), or a broken ring (in which case it would probably be smoking like a freight train).You probably need to dig into it.
1. A young guy in a sports car is probable cause. It sucks, but that's the way it is. I learned quickly NOT to have stuff on my car that attracts attention. Drive within the law, and you usually won't have a problem.2. Pacing you is a perfectly legit way to measure your speed. I know...
They are used in all sorts of classes where drag cars are required to run some type of muffler. At those events, flowmaster and borla is about all you'll see bolted to those cars.And I agree with the other comments in this thread. The butt dyno is worthless. Too many variables to account...
Well, every car magazine has probably done muffler comparos in the past 4 or 5 years. probably wouldn't be that hard to look up.Typically, Flowmaster and Borla come out on top as making the most power, with other trailing by different amounts.
Galsspacks will typically neck down first off. Even though the inlet/outlet is say, 2.5", the ID inside the muffler might be 2".Also, all of those stamped louvers create a ton of turbulence, which is bad.That's why glasspacks suck.
A "turbo" muffler seems to be a marketing term more than anything else. What makes a muffler a turbo muffler?The glasspack is about the worst muffler you can have, some stock mufflers being the only exceptions. On top of that, they sound like shit. It's a very restrictive design.
And what kind of math are you doing here?One 3" pipe has a cross sectional area of 7.07 square inches.Two 2.5" pipes have a cross sectional area of 9.8 square inches.Now which of these has the greater area?
It should go down with more cars than drivers, but you also need to see which car you are primary on.And when you turn 25, it'll drop.I'm 29, and my insurance for my '98 Grand Cherokee (full coverage and then some) and '93 Laser (liability only) run me $100/month.Not that those...
Coming from "the other side" where 4 cylinders is only half an engine and guys actually need 3" or larger dual pipes, you're gonna get laughed at.Every time I see a car that has a 4" tip, I crack up...especially knowing that it'll probably only wheeze into the 15s on the track.It really...
See, I'm confused...what's the big deal with converting a FWD to AWD? The tunnel is already there, which would be the biggest problem.Also, about the front knuckles....certainly no reason to ditch them. The do need to have some bolted connection to keep the bearing together in the front...
