I have a borla two outlet resonator. I want to have this installed so I can drive the car without fear of blowing a head gasket. I have looked through the archives but not much there.
A lot of threads and faqs on this forum also point to our exhaust ...specifically the resonator as a bottle neck.
Changing the resonator will not do anything to help your head gaskets. They blow due to time, torque to yield bolts, electrolysis in the coolant, detonation, or overheating. A freer flowing exhaust will help performance, but if you are concerned about the head gaskets blowing on you, you would be better off just replacing them now, getting the heads checked/resurfaced, and using ARP head studs to put it back together.
A freer flowing exhaust yields less heat especially in the heads. So it will help in general. Do not replace headgaskets until needed. You need to open outlet on manifolds. And 2" or 2 1/4" down pipes to resonator. Then....
Looks as nice under as it does above - I hope you sent the 2nd image in for the calendar
This article touches on exhaust temps and measured pressure. I don't have a frame of reference but per the author the 15 psi back pressure our stock exhaust creates is way too much. I hogged out the outlets on my car but still need exhaust work.

Thanks! Those are ADDCO 1-1/4" sway bars.Those pictures are very helpful and the car looks awesome. Those are some monster sway bars.
While the car pictured above is a '90, that is a '92-97 fuel tank, so you'll have the same routing/space to work with on your '95.I should have mentioned mine is a 95 but have seen that this year should be even easier.
The "resonator" is in fact a muffler. It's a straight-through crossover design, but it does reduce the sound level. Between the cats and the mid-mounted muffler/resonator, it's aggressive, but not overly loud. Here are a couple of videos. Keep in mind, this car isn't a V6 anymore.I see you are not running mufflers. What is the sound level inside the car? I was planning to start slow and just have the resonator and separate outlets with stock mufflers. I was hoping to stay pretty stealth.
