Obviously the silencer must rob alil power otherwise the exhaust would be permantly that way; how much power is stolen? Signifigant?

 

Prob around 2-3 hp. not much but a noticeable amount.. remember an exhaust doesnt give a significant amount of hp to begin with .. I guess it depends on your set up as well.

 

2-3whp. You may "feel" it top end, but more likely you won't.

 

In other words; in a quiet *** town its worth having the silencer on? hmmm trying not to wake up the parents.....

 

Judging by the outlet diameter of the typical silencer, I would estimate more than a 2-3 whp loss. The silencer creates a serious bottleneck in the system, and I would be very surprised if an aftermarket exhaust system with the silencer in place didn't actually make less power than stock.

 

Whenever I put my silencer on the revs dont seem to rise as smoothly as without the silencer

 

i lost 7whp 5wtq.

i lost everything the exhaust gave me when i put the silencer in.

 

i should try my Spoon N1 silencer next time on the dyno to see if there is any power difference, I never use the silencer and come home around 2am maybe 3 days out of the week, if not more, if the neighbors dont like it they can suck it easy

dynojet numbers on my TRM + silencer = -8hp compared to running without it. I did the test 2 years ago just for that reason = justification

 

I would say try it out and see if you notice a difference. Everyone's cars are different and everyone has different taste. You may notice a difference that is significant to you, you may not. Try it out before making a decision based on the opinions of everyone else, your outcome could be different.

 

Here's a dyno of a Type One exhaust w and w/o silencer.
