building a ef sedan, need to know what exhuast is good. have a b18c and about to boost.

 

There are no off the shelf, high quality exhausts for the EF sedans. Custom is your only real option.

 

I highly recommend mandrelexhaustsystems dot com. $120 for all the tubing you need in a kit with hardware and hangers. can be clamped together or welded up.

for muffler and resonator:

low-cost, high quality, "sleeper" look- Jones Exhaust Full Boar oval. can be found in many different sizes and offsets on SummitRacing

higher cost, better looks, "brand name"- Vibrant STREETPOWER universal mufflers.

I used the Jones oval with a 2.5" tubing kit on my EJ6. I added an additional flange near the fuel tank to make install and removal easier. I welded the resonator into the mid-pipe section but used a clamp (see bellow) on the muffler incase I decide to try something different in the future. I probably won't. The Full Boar has a sporty sound without being loud.

 

Tganks , that really helps. Can't seem to find anything unique. But that does help I'll look into that.
