Yeh that's it; 2 less 90*s with their oh-so-sharp corners. Seems to work ok for the factory. And it may still for HO, but to my way of thinking I was having none of it. With TTIs there is plenty of room for a shorty filter in there.
Cool. Running stock 340 manifolds right now, but I'll keep that in mind. I do plan on adding TTI shorties in the future. Maybe the small filter will work with them too.
