^Does your local muffler shop mechanic know a lot about fluid dynamics and the flow characteristics of an internal combustion engine's exhaust system?

 

You are correct that the gains if any are very minimal and definately not noticeable because when the engineers design the parts they consider the maximum quantity of gases the engine outputs STOCK and put components that can flow that quantity. However this does not mean its not restrictive, just that the engine doesnt output does t exceed the capability of both mufflers

 

Not a bad bump. Kind of wish the vids were still available.

any way to hear this? it looks interesting and I'd love to see how it turned out!

 

Agreed, I want to hear this. Cheap afternoon job for me to do!

 

I would imagine it sounds identical to straight pipe? I deleted my rear mufflers, it's just louder, doesn't affect tone at all. I wonder how that would sound if there was no pipe, just hollow, it would probably act like a resonator then but flow the same.

Has anybody cut open a mid muffler? Just curious if there's anything restrictive in there as I still have mine.

 

The mid muffler is just straight through. Nothing to change up in it, Just cut it out!

 

nice look inside the muffler.

 

You never fail smog because of no mufflers, it's not part the inspection... I'm a smog tech

 

Holy thread revive

 

Very nice!

 

Wish I could see the pictures we are thinking about doing this

 

Somebody should consider doing internal modifications to the 2g RL 05-08 and 09-13 year models. They have pressure activated valves that open and close depending on exhaust flow for increased back pressure at lower engine speeds and reduced back pressure at higher engine speeds. I'm sure by removing some of the deadening material, noise levels could also be gained when the engine speed increases if removed from the proper area.

 

Exhaust setup if you have pcd and j-pipe the sound will increase , im curious with this mods with pcd+j-pipe and stock exhaust
