I have been looking into getting an exhaust system for my IS250 and was looking for any recommendations or advice. I have seen that not all the exhaust systems are compatible with the AWD models because of the midpipe and want to know which systems work with my model car. I'm not overly concerned about pricing at this point, just would like some ideas which systems are good for some extra noise and performance. Thanks.

 

Wouldn't worry too much about AWD compatibility, if the one you want isn't specified for it. The axle-backs are all bolt-up, and for AWD you'd just need to modify one of the pipes on a catback. Check my build thread for pics of mine, which was designed for RWD but muffler shop modified. Maybe 20-30min of work.

 

Tanabe Medalion Touring Dual Axel-Back Exhaust

 

From the YouTube video Tanabe posted - isn’t this exhaust the same if not quieter than stock exhaust?

 

I heard invidia finally made a awd version for their midpipe. When I had mine installed they just modified it to fit.(There was only rwd at that time).

 

Several companies make a full exhaust for AWD:

Invidia
A'pexi
Ark
JoeZ

 

Definitely not, the Tanabe is definitely louder and has an awesome deep growl. It's not super loud either as it is made to be within the legal limits. Videos don't do it justice trust me.

 

For full exhausts we can do the Invidia, Ark Performance or Apexi.

For just axle backs we can do the Invidia, Tanabe, Apexi!

There is no after-market exhaust as quiet as factory Lexus (if there is I want it).
