Re: Mufflers and/or Resonators - what combo to get?
If only it was that simple.
Generally speaking the idea is that you want to have as much of your muffler capacity as far away from the engine as possible (for performance). But this neglects other factors such as noise etc. Plus of course what will physically fit under the car.
On your car I'm assuming you'll run a single exhaust so you should have room for a good size straight through muffler (I always push the Magnaflow range as having the best sound) noting that the ultimate sound level will be determined by the factors of length and muffler cubic capacity. You can then 'tune' the resonance by selecting a rear resonator to suit your needs. Some people don't need a resonator but I'm old and all that! In some cases a hot dog would also do a good job of providing 'tone'. The idea here is to tack on a rear resonator and drop the car to the ground and see how it sounds in and out.
Just for info, cheap mufflers or poorly made ones (by inference I'm trying to tell you some places charge heaps for crap) are edge welded, have the in and out pipes in unsupported flanges, do not align with the muffler body, and are made from thin sheet. These mufflers cause a tinny sound and greatly increase resonance in the vehicle. A good quality muffler can give great audible noise outside yet not cause resonance on the highway.
