Im looking to buy an exhaust system for my IS300 and dont know which one to buy. I know that I dont want a loud sound, I just want a deep sound that sounds good and improves performance. This exhaust will go along with a INJEN intake. Which should I go with?????? Thanks (Remember that I want the best performance)

 

Go with the SRT or Rod Millen intake. The INJEN(I have heard is a P.O.S.) . AS for exhaust....all depends on what you are looking for. HKS Dragger cat-back sounds sweet but makes alot of noise in the car(kick a$$ power also ) I don't care about noise because I like my speed....

 

Try the L-Tuned exhaust.

 

hks hiper for power gains...even though it's only a rear section, people on is300.net claim it's the most power out of the box......

i have carbon ti, similar, but sounds deeper and looks better...IMO
