    Does anyone have any good ideas as to how to enhance the exhaust sound to give it a little more roar? The sound of my QX70 is not bad, but I'd prefer a little deeper and louder purr. Thanks!

    For the FX37/35, I think the best sounding exhaust is the Ark Exhaust. Search on here a few guys have it.

    Personally I like the sound and quality of the ARK. Exhaust is likely the last major mod I'll do.

    This video is from our Russian friends and gives a nice side by side of the two major options for full replacement. There are several other videos on YouTube worth checking out.

    Thank you for your suggestion. Any ideas regarding a chip to enhance HP and performance for a QX70?

    BullyDog now supports the QX-70 but I had to return mine because I got an error and they are too slow to respond. This was several months ago. By now it may work without a problem.

    I just replaced my factory muffler with a "Borla" for me it sounds perfect and I didn't trash the rest of the system.

    The ECU figures it out in just a few miles. Finally she purrs. For a while I was missing my '03.

    Thanks, Old Blue. Sounds great! If I may ask, what did you pay for the Borla muffler? Thanks!

    $139.99 at summit. Sorry I didn't see this. Muffler shop did a great job but it was another $400. I'm happy with it:cool:
