2016 Corolla LE ECO

[H-Man]

I say leave the drivetrain alone. How do the wheels look? I'd do rear wheel skirts and smooth hubcaps.

Which magnaflow muffler did you get? I called up flowmaster and they were saying the magnaflow ones are a glass pack and they can burn up. Did yours last pretty well?

I've only had it for a year. It's not a multi chamber one though, so it might get louder with age, no idea.

My Dad had Magnaflows on his Mach 1. The packing inside was supposed to have been some steel and ceramic materials, supposedly much more durable than regular 'packs. The principle is the same, though, hence the crackly glass pack quality their sound has. He only had that car for a year or so, so I can't really speak to their durability.

I have regular glass packs on my Mustang. She was my DD for a couple of years. They didn't seem to burn out all that much. They're longish, 24" I think, maybe 30". They're still quite mellow.

should i just go ahead and put a glass pack muffler on instead of the all chambered one? its about a $30 difference in them. I think the glass pack should sound the best of the two but I’m not sure. it should help weight reduction a very small amount but being less restrictive should help right?

Not really, you're losing maybe a lightbulb or two's worth of power to exhaust backpressure, and most of it is at the cat not the muffler.

Again, do it for weight reduction or sound (and neither will really show up at the pump), not for efficiency gains. Mufflers don't give you squat in most cases.

So, looks like I'm getting worse gas mileage with the K&N? Is this possible? I don't get why that's happening. It's never happened like that with any of my other vehicles. It either stayed the same or went up a bit. Never down.
