The engine in my 1995 SC300 is super loud and 'grunty' (?). The VVT-i motor in the 03' IS300 that I had was super super quiet. The SC sounds like it's working too hard after 3K RPM. Any ideas?

hole in the exhaust like me ??

No, the sound I'm referring to is from the front end of the car, maybe it's a leak on the manifold. It reminds me of the old 280z engines, they were really loud.

does it have a hissing sound to it.

Lvangundy

No, what I'm trying to explain is the sound made from the block itself, it's just noisy compared the IS's 2JZ-GE motor.

Engine compartment is insulated better on the new car

I don't know, might be isolated to your vehicle. I had a 93 which was soooo quite (until I added the BFI) and was comparable to the 00 I drove the other day.

Maybe cracked exhaust manifold? That would make the engine "louder" in a sense. Does it have a throaty sound to it?

yah my engine has a real aggressive sound to it. I can hear it over my exhaust when i romp on it, after about 3-4k all i hear is the engine screaming. I like it

u have to agree, it is a loud motor. im sure it has a little to do with insulation, but even with the hood up, the IS is a lot quieter than the SC. i actually like the sound. my SC with the stock exhaust actually has a bit of a growl to it.

mine is like that too... its all engine-noise after 4k, and my exhaust is LOUD. it isnt even an intake noise, its just the engine working. puzzling

Yes, mine is rather loud as well....I was expecting something much more tame from a stock lexus.
