morellja Posted January 19, 2013 Share Posted January 19, 2013 I apologize if there are millions of posts about exhaust, but if I could get some real quick opinions that would be great. I am running a built L28ET in my 78 280z and it currently has a straight 3" pipe all the way out. It has become or I have become to old for the noise level. I am looking for opinions on free flow mufflers and if I should get a resonator also. I just want to quiet her down a bit, but I do not want her to sound like a little biotch...Any help would be appreciated. I am looking at the Borla XR-1, but again I would like to know if a resonator is a good idea, especially with the turbo, even though all these components are suppose to be free flow. Attached eye candy too. Thanks, John Quote Link to comment Share on other sites More sharing options...
78zstyle Posted January 21, 2013 Share Posted January 21, 2013 I used a magnaflow straight through with my setup and it sounded great. Quote Link to comment Share on other sites More sharing options...
morellja Posted January 21, 2013 Author Share Posted January 21, 2013 Mind hitting me with the model # on the magnaflow. I am getting mixed signals on what will work. Some say 18" is to big you need a 14" some say 16"...yadda yadda Quote Link to comment Share on other sites More sharing options...
ztime Posted January 22, 2013 Share Posted January 22, 2013 Nice looking Z John. I went with a Dynomax center in/out on my 75 L28ET swap. 3 in. straight thru, 14 in case, and sounds great. Quote Link to comment Share on other sites More sharing options...
Pharaohabq Posted January 22, 2013 Share Posted January 22, 2013 I like quieter sleepers... so for me, Yes a resonator is planned. It won't really hurt your HP noticably. That and a decent muffler, I'm hoping to still be able to hold conversations in that car while on the freeway. if it hurts my wife's ears she won't ride in it. so I have some constraints.
