Anybody use this one with good results? 3in IN duel 3in OUT. I like my edelbrock now but want something a tad more musclecar sounds like with the new 383. Let me know.

 

Yes I have this same muffler on my Z28. It is very loud with my SLP headers and no cat. Very aggresive tone at idle. A slight tin sound from 2500-3500 then a good sound through 6500 rpms. Of course I have a puny 355. Might sound alot better with a healthy 383 pumping out more sound

Either way I still like it. On long trips I kinda wish it was a tad quieter, but I need something to listen to since I won't put a radio in it.

 

I was looking at the same muffler. Heard good things about them. FastZ28, have you heard a flowmaster 80 series? Thats what I got and was wondering how the two compare.

 

No I have not heard a Flow 80. I have a movie clip of me autocrossing with sound. Its not the best, and its only mono sound. You can check it out here.

 

Dang, that sounds good. Think that's the first time I've heard that muffler. Completely different sound to mine which is more raspy.

 

Matt,

Spintech muffs sound awesome.. Id deff say go for it. I think Ive told you that even befor the 383 build.

What happen to getting the GMMG rear section?

 

$$$$$$$$$$. I just need to fine 3 in tail pipes now seperatly since my intermediate pipe and over axle pipe are ok.
