It is getting too annoying dd'ing with the straight pipe, so time to put a muffler on. I'm trying to decide between a glasspack or actual muffler, i dont know how much either will quiet my exhaust down. Basically going to buy a cheap one from summit, which type do you suggest? And hopefully it still sounds alright.

*****!



i say get a Borla...........

 

I fully recommend a quality muffler. A little resonator like link#1 wont really do ****, it will take out the rasp and that's about it. The second muffler is chambered, and is just absolutely garbage for a turbo setup. What you want is something more like this:
Dynomax 2.5"

6" case with enough packing to really take some volume out. I have the magnaflow equivalent of that on my car with 1 resonator and its VERY nice on the street. Sounds like a slightly louder stock miata to be honest, but it has a nice smooth tone when you get on it. If you run it without a resonator it would have a fairly quiet, but still raw sound.

 

thanks, exactly the answer i was looking for.

is this similar to the one you have? what is the difference between the Perforated stainless tube with packing in the magnaflow vs the
Glass-wrap perforated tube of the dynomax.
I've never really set up an exhaust before so thanks for the help.

 

That's pretty much exactly what I have. Heres a video that JayL took at the dyno day last weekend. Obviously the sound is a little distorted because of being in a building, but you get the idea.

 

The overall diameter of the case makes a big difference because it requires volume to absorb the individual pulses. That volume will also give you a deeper tone. The material in the case makes a difference as well. Glass doesn't last.

 

Cherry bomb glass pack, from your local pepboys for about $35 bucks and a magnaflow straight-thru muffler. should spend about $100 bucks total.

 

A cherry bomb works great for about a year. You may as well just hollow it out when you put it on. I tried using one on my exhaust as a resonator when I was N/A.

 

I'm a big fan of magnaflow. Put them on most of my cars that I want to keep the noise down on.
