So my beautiful, wonderful girlfriend surprised me with an early bday gift... She took my credit card away when I went to pay for my custom setup and said "Happy bday"

Below is a map of the exhaust setup I got on my 350z. The exhaust was installed on Saturday, and I did not have test pipes at the time. So today I added them and while I was expecting the car to get louder, it got a bit too raspy for my tastes so now i'm looking at adding another set of 14inch resonators right after the test pipes and before the X pipe OR right after the existing 14inch resonators right before the muffler. From all of you guy's experience, will adding more resonators silence the exhaust a bit and if I add a couple more, what am I expecting in terms of power loss..

Here is what the exhaust looks like. The preforated lines are where i'm hoping to add the additional resonators.

 

Just get resonated test pipes and sell your non-res pipes to somebody else. AFAIK, resonators don't cause restriction.

 

Just curious...how much did you pay to have your custom exhaust built?
