Let's take a look at the Tanabe Sustec Z40 Coilover for the Lexus Is 2nd gen

Here's the car at stock height

Here's the Coilover's highest setting

And here's the lowest height setting

We tried the tower bar on the IS250... if you noticed we had to take off the engine cover for it to fit over.

 

Here we test the IS250 stock Y-pipe and the Tanabe Y-pipe and put them on a dyno!

Here we test a mid-pipe for the IS350. We compare the stock dyno, the mid-pipe, and the Tanabe Medalion Touring Exhaust with the mid-pipe.

Medalion Touring with midpipe:

 

 

As you all know, we worked on a midpipe for the Lexus IS250/350. These are the results from the dyno of the stock IS350 with only Tanabe's resonated midpipe, bolted to the stock exhaust : 

 

So as you can see here, Tanabe's resonated midpipe has made quite an improvement in horsepower, almost 10 horsepower more, and almost 7 more pounds of torque.
