Thanks for all the replies.. In case anyone's curious, here's DynoFlash's post on the subject from a while ago. - https://www.evolutionm.net/forums/dy...cer-sucks.html

 

never heard of that or seen it happen before

 

damn would not of expected that either
but haha people have bad luck.. running open downpipe for months and still nothing

 

I believe import tuner conducted a dyno run with and w/o a silencer(Acura integra). There was no discernable difference with our w/o silencer. This was for NA cars although there was a difference b/t boosted cars and NA. I'll look for the link.

If the "silencer" you're referring to is the black piece in the back of the picture, you will see zero hp loss or gain. All it does is keep sound waves from bouncing around in your muffler and increasing bass and amplitude.

Why not weld in a resonator?

 

The silencers definitely make a difference...regardless of whether or not you're running a cat/piping/etc. Just for giggles while dynoing my S2000 a number of years back, we put the silencer in to see it's effect...12whp loss. Not huge by any means..but definitely changed the car's output. Unfortunately I didn't keep the dyno sheets...

Kinda like necking your 3" exhaust down to a 1.5" exhaust.

 

Resonator ftw

 

Its not a matter of losing hp, but air going back into ur turbo damaging it!

 

Now Explain how this is Possible? when the 2 are at different ends

I just put in a Silencer into my Turbo XS, which I want to replace b/c it drones so much, (it came w/ the car)now I enjoy my pulls w/ out the loudness, it's still loud of course at WOT but not the droning that I can't listen to my music unless turned up high. If there's a loss, it's a tad of loss....but to be under the radar of ******** cops, it's a good way.
Because at the end of the day we all know our cars are Louder than normal cars, so the deal is trying to deter the extra Attention by the law, which Nobody likes to pay dumbass tickets for loud exhaust.

 

the faster the air flow out the exhaust the better the turbo breath ans spooled so if u put in a silencer which is reducing the the air flow from exhaust is will have some performance losses by creating back pressure on the turbo

 

Where can i get the silencer? i just got my evo 3 months ago and i can't determine the name of the exhaust (it says nothing in it) and it rumbles all the walls on the garage when i turn it on . It gets to loud on the highway .

Thanks

 

Never seen a silencer NOT affect the power, on an evo, or any other decent power vehicle. Maybe no effect on some small power vehicle. Wishful thinking on your part eh?

 

Whether it effects the power or not, I couldn't stand having that ugly thing in my exhaust. If they are aren't painted black like the megan one shown, they get exhaust stains as well that look like diarrhea.

diarrhea lol great analogy
