True, but you never know until you try. Well designed headers and high flow cats mated to a true dual exhaust could net a lot of power across the entire powerband without dropping anything down low. Since this is a motor nobody's modded yet, it's up to the brave pioneers to find out.

it's possible to lose low end power while gaining top end.. Which is not
what i imagine we'd want, since our IS350'S don't seem to be the kinda of
car you want to take up to 150mph,, (maybe on a perfect straightaway)![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)

I agree.. I've been out of the high perf car world for over 5 yrs now, but
I don't remeber there being any high flow cat systems? Do you mean
straight pipes, with no cats??

I'm not sure if the IS has two sets of cats or just one, but if it is two, then a set of high flowing cats will help free up some power. Even if just one set, it's possible that high flows would help a little. I personally like hi flows for N/A engines -- I think straight pipes sound way too loud and smell like ***.
