Monster, read the whole thread. I said a guy LOST 40whp from using the tail silencer on his TBE. In other words, it's MORE restrictive than the stock exhaust.

Yes, a TBE should give NO LESS than 25whp. It's usually 30whp or more, though.

 

Bottom line is that it is not reccommended if you want to keep your power up. Get a quieter exhaust if you don't like how loud your's is. But it's your call. Just make sure your happy with what you do. I personally would not use a silencer.

 

My Mistake... Thanks

 

no doubt thanks guys

 

well im trying to make my evo lil more quiet too, gotta straight 3in all the way from downpipe, what u think about that???

http://www.dynomax.com/mufflers.php - ultra flo, looks like pipe inside got same diameter that inlet and outlet pipes so it shouldnt make more back pressure and i know for fact that in my buddy's turbo lexis is300 made it waaaaaaaay more quiet

 

Ok, here's a test:
Run around the block as fast as you can, and then record your time.

now, go grab a coffee straw and use that as your "breathing tube." You can inhale just as you normally would but you can only exhale through the straw. After you have taped it to your face, try to run around the block as fast as you can.

If you don't die, you may notice a distinct difference in your speed/respiration with and without the straw. This is exactly what you're doing to your motor.

All joking aside, resonators, high-flow cat (if you're catless), and experimenting with diff mufflers can all quiet you down.

 

thats my point, diameter is same as pipe, 3inches, and some fiberglass around, nothing stops gas flow

 

Resonators won't hurt you, silencers will. There is a very noticeable power difference.

 

+1. After I got my new exhaust, I put the silencer in just to see what the difference would be... Drove around the block, parked the car, took the silencer out, and threw it right in the trash.

 

I found a Cobb Exhaust & Megan resonated test pipe, you can't get quiter than that on an Evo at idle, WOT is a different story....

But I did try the Silencer for a while & I was in denial of how slow the car felt.
Silencers are a temp fix.....

 

Someone did a dyno comparison with the silencer and without on these forums. There was a huge power difference. Check out the search button.

 

end of silencer subject, im talking bout resonators now, so now effect on power but what about noise???

 

What are you saying?!

 

Engrish translation: "Relax there buddy! Who are you, the computer police?"

 

Silencer is gonna sound nasty. Hhahha!!
