It's usually the other way around. Intakes are, in pretty much every engine I remember hearing about, larger than exhausts. The stock 2.0, for example, has 42mm intakes and 36mm exhausts.
Dunno why the Ti ones would be different. --DD |

Its a typo on their part. There is actually a formally used to determine exhaust valve size compared to intake size... and the exhaust never ends up bigger unless (unless) you have a multi valve head like a 5 valve or something.
Then again.. they may be telling you the largest they sell for intake the and largest they sell for exhaust (doubt it) B |
