shelbyone Posted April 14, 2017 Share Posted April 14, 2017 any suggestions for any kind of performance muffler that maintains the same look ( 2 pipes) and is still legal? Link to comment Share on other sites More sharing options...
TwinCamFan Posted April 14, 2017 Share Posted April 14, 2017 Even in overregulated California you can put any muffler you want on and it's still emissions legal because it's AFTER the catyletic convertor. Turbo motors want as little back pressure as possible so free flowing is good for mileage and power. To retain that original look I've used a high flowing 2.5" in/out performance muffler and had a 'dummy' (fake pipe) added next to the functioning outlet pipe. Looks great from above and flows well. Best of both worlds Link to comment Share on other sites More sharing options...
RTW Posted April 14, 2017 Share Posted April 14, 2017 I think that if you are looking for a performance enhancement, you probably need to replace more than the muffler. You need to change the pipes and the cat. Link to comment Share on other sites More sharing options...
