: QTP exhaust cutouts - Sedan placement

04-28-13, 01:59 PM
I am about to order a set of oval low profile cutouts from QTP.

I have a 2009 sedan - Where would the optimal placement for these cutouts be? Since I drive clients in my car on a regular basis I do not care for keeping them open all the time. I would like have them installed in the best place for performance gains if any.

Any pictures or drawings would help so I can show my mechanic.

Thanks in advance!


Has anyone use the following setup? I just ran into this while researching these cutouts.

Any help would be appreciated - I did search and found a bunch of people put them right before the mufflers... I doubt that is the optimal place?

That is not the optimal place for performance but most of us did the cutouts for sound alone. It's an easy fit in that spot so that I where I put them. For performance you'd need them before the cats...but I don't see a place for them to fit before the fronts. Good luck!

I thought that most put them at the inner bends just below the trunk area. I KNOW that they have videos of them here somewhere.
