Sorry in advance if there a thread on this already but I looked and couldn't find one. Anyway, I have been looking into stright pipe exhaust as well as a full tuned exhaust system specifically Megan racing. I have a 2013 wrx premium and I'm considering my options.
Option 1- Megan racing up pipe catless with flex section
Megan racing down pipe catless
Megan racing catback exhaust
*keep in mind Megan makes a 3" system with no step downs
Option 2- Same Megan racing up pipe and down pipe then straight pipe to exhaust tips on the ends or to a muffler of some sort.
If someone can give me advice on something they had tried, or good idea vs bad ideas. I know goin Megan tuned system is a tried and true system although far more expensive but a few subie guys a know love the straight pipe route. This is my first wrx so I'm not entirely familiar with their intricacies so any advice would be a great help.
