My car finally plugged it's cats . I lost all power above 4k RPM along with a lovely kazoo sound . I removed the cat's and my car had power again but it's too loud to drive .
I Will be picking up a RB system this week but don't know If i should but the Single exhaust for the 79 or the street port dual exhaust one . I have a Automatic and a stock port. Due to my stage 2 gearing on my trans I highly favor low end power over high end power.

Which exhaust is recommended?

 

if u plan for more power later on when that engine is done, i'd go ahead with the dual pipe one. it's what i have and it's nice and quiet.

 

I don't plan on upgrading at the moment but if its Quiet thats a +1

 

If you get the RB system, you want the long primary version.

 

So the dual pipe .

 

I ended up with the short header , They said it won't work with my Trans and is about 50% louder

 

Question . Does any one know where to source the metal doughnut gasket between the midpipe and muffler. It's NLA and no one seems to have it
