Where is the best placement for mufflers?

-close to the headers, middle of system?, End of the system? Or doesnt matter.

I have block huger headers and intend to run 2-inch pipes into a Y and a single sport muffler and one tail pipe.

Will it perform better and be less noisy if I have the muffler near the back with a short tail pipe?

I want to do the pipe work my self. I hope to fit 3 inch stainless side pipes at a later stage, but for now a 2inch mild steel home built job that is inexpensive and will pass rego is what Im after.

Any thoughts?

I have a theory,Depending where you place the muffler can affect the "note" if you have a muffler of the sports variety,however the ideal I find is usually up toward the front around the drivers seat area,the other usual spot is just forward of the rear axle,the further back you go ,the muffler is subjected to a higher risk of corrosion.............

Yeah, the condensation will build up if the muffler is rearward...The note is deeper if its rearward..well thats how I think.

I agree with that concept Pep ,the further forward seems to give more"treble" to the exhaust note ...............Frank.

Yeah Frank...there's enough twists and turns for the exhaust to find a way out its a wonder the sound doesn't still keep going for a minute after you shut them down
