a exhaust question

[shady milkman]

so i know i am not alone....

after i went long tubes with a ORY matched with my magnaflow catback i have noticed something odd.

when i give it throttle ..my driver side exhaust is the only outlet that is showing exhaust "smoke" ...i am sure both are pushing out gases ..but the driver side is pushing so much more . when i drive i look out my back window and see the driver side really puffing while the other side is not noticeable.


so why does it do this ?

[0verkill]

it must be the muffler i have the same set up and get the same thing

[pajeff02]

Same thing here, only with stock manifolds and Y going to my Magnaflow catback. No explanation other than the exhaust would have to turn to exit the passenger side pipe -- path of least resistance is the driver side.

Same deal on my car. Magnaflow muffler design,particularly at idle. More passenger side exhaust under throttle than idle

[luvmyz28]

same here.

Come on guys isn't it obvious ?

pajeff02 nailed it "the exhaust would have to turn to exit the passenger side pipe -- path of least resistance is the driver side."

The single muffler systems that use the stock configuration will always do this because the gasses have to turn 180* around inside the muffler to exit on the right side. This creates turbulence and a loss of efficiency which hurts flow and power output.

This is the reason behind the existence of the Old SLP Dual on the Left, the `98 Only Single on the left and any subsequent aftermarket (Mufflex) single out systems.

path of least resistance is the driver side.

There's the obvious answer

well i assumed that was the issue..i was just surprised how much of a difference there was ..even with long tubes etc.
