Muffler Question

are you talking about stock mufflers of aftermarket mufflers? it all depends on the muffler design. i would assume that stock mufflers on higher horsepower cars would have higher flowing mufflers, but of course, manufacturers want to pass inspections and keeps costs down. i would just research aftermarket mufflers and see what has good flow with good noise suppression.

yes, im talking about stock vs. stock...*original post edited*...the reason being, i have decided to get rid of the canister on the ae86 and im looking for something stock looking and sounding...i have the lexus ls/gs/sc muffler in mind, also considering the is300 muffler...and almost every car has more hp than the ae86 : so thats why i was looking for stock muffler from a car with a larger displacement engine

A stock muffler off of a larger displacement engine is a larger pipe and a higher flow cat... Not to mention the bending of the pipes... a lexus pipe wouldn't even be close to the curvature of the 86.

An example:
My toyota (4A-FE, when fitted): 1 3/4" pipe and flanges
Ford Falcon I6: 2 1/4" pipe and flanges
Ford Falcon V8: 3" pipe and flanges.

You are better off getting the after-market muffler sets.

I know what you mean. Well.. yes theoretically the mufflers from bigger cars should flow better.

thats what i thought, im not doubting u Flashmn, but can anyone confirm this? or does anyone have any first hand experience with this?

OT, but this is my 100th post !!! :woot:

What i did was, well i duct taped a large coffee can to my pipe....then i went out and bought a 3 1/2 foot tall wing, and i got some APC stickers.:lol:

no really there are those double barrel N1s that look stock. They look like a shiny stock muffler with a little bit bigger piping.

Well think about it, you would expect lets say a 3 liter I-6 to flow more exhaust gasses than a 1.6 I-4.

^Sounds reasonable to me....
