exhaust cut-out Q's
hey i was just wondering what you guys think of putting the electric exhaust cut out on our cars im thinking about putting one on just because its the ultimate sleeper part. You could have a quiet exhaust when u drive to work, but then when your at the track or just wanna show off you open it up and have a free flowing exhaust. So what do you guys think.
FWIW, exhaust cut-outs work well on cars with poorly designed exhaust systems, but work poorly on those with well designed exhausts. I would wait to see how much power can be attained by a very good aftermarket unit before I would go installing something like this. If Lexus did a good job on the stock unit (which they probably did), installing one of these might result in reduced power whether the valve was opened OR closed.

I know that this car is NOT an S2000, but there have been MANY companies that spent a LOT of money trying to improve on its exhaust only to find that they couldn't, and eventually abandoned the project. Note that the reason why I keep brinking up the S2000 is because its exhaust was very quiet with a premuffler and dual triple pass mufflers.
All I'm saying (since you asked) is that you should probably wait to see what the best aftermarket exhaust does for the car. I know for sure that an open header will cost you power on any modern performance car, and installing an exhaust cut-out will have similar effects.

I actually had an exhaust electric cutout on my Dodge Ram 1500 w/HEMI and it sounded awesome as hell, but that was a V8. On this car I would be worried if it would sound like a lawn mower or some riced out civic with a fart can exhaust. If it sounds good I would do it even if it showed no real power increase. It can always be left closed for more power or open for intimidation purposes. I will contact the company that I bought one from since it was the best quality unit out there and everyone bought from them on the dodge boards. The company is called DMH performance and it comes with 4 year warrenty if I'm correct. I will call him and see if he can make one for our cars. Anyone in Dallas area that would volonteer for testing? you'd probably get the unit for free. He does GB's too....

Sorry for bumping an old thread, especially one with so much ignorance above by a certain poster.
Anyway, did anything good come of this? Did the OP end up getting the cut out and how did it work? Any check engine light or O2 sensor issue?
