I have the Apexi N1 dual and was wondering if anyone here has it with the silencers. I wonder if they would give the car a lower note as well as making it quieter. Also do you lose power when you add the silencers?

You'll lose a lot of power puting in the silencers. It will make it quieter, but will not lower the note...and it sounds like crap with a midpipe. https://www.nopistons.com/forums/pub...IR#>/boink.gif

question: y would u lose power with the silencer though?

Silencer puts backpressure on the turbine. Might as well run with a catalytic converter if your going to run those restrictive freakin' silencers.

understood

You don't want a silencer. I am getting a midpipe put on with a borla welded in and it is gonna be loud..





My n1 dual is my friend.



I like it. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif :bigok: https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

I would actually look into getting a different exhaust Dave. Not for the sound, but because of the size of the exhaust inlet on the n1 dual. I used to have it and I did a side by side comparison. It was the smallest out of my comparison with a Blitz, HKS, Greddy, and JIC that I had underneath my bed. https://www.nopistons.com/forums/pub...IR#>/boink.gif

No ****? You mean at the opening for the midpipe end right?



Hmm How much difference was there?





I hate to lose my twin pipes.



What do you guys think of HKS cat backs?



I heard one once on a Supra and it sounded nasty loud and raspy.. I loved it.

That would be the one Dave! The HKS will give you a lawnmower sound, especially if it's a canister style. It's VERY hard to get an FD to sound good.



It appears to only be a 2 1/2 inch inlet from the midpipe. Your midpipe should be a 3" and your frontpipe should be a 3". That would suck to lose horsepower because of a muffler https://www.nopistons.com/forums/pub...IR#>/boink.gif



I think that mike(j9fd3s) said that it made a world of difference when he went to 3" exhaust. I actually never put the apexi on because it looked so restrictive... https://www.nopistons.com/forums/pub...IR#>/dunno.gif

Hmm ok I will see what I can come up with.



I haven't looked at exhausts in a while, this might be fun.
