Hi guys,
I recently had TGV and EGR deletes along with a Grimmspeed catted j-pipe installed (and restrictor pill removal) and pro tune for my 2017 WRX. The j-pipe is mated to the SPT catback and the exhaust gives a nice deep grumble, but gets a little droning at highway speed. It doesn't bother me so much as my wife so I'm now I'm looking at better options. The shop that did my tune has the Mishimoto catback as well as Grimmspeed catback in stock, and can get others in as well. YouTube clips seem to make the Grimmspeed resonated catback the quietest sounding, but the Mishimoto has a nice deeper rumble. I know, it's hard to discern exhaust notes on YouTube and I really need to hear them in person.
Aside from keeping the wife happy, I'm wondering if going to a 3" pipe like these aftermarket catbacks are would give any higher power figures than the SPT catback, which is 2.5" as I am told? I know with the stock j-pipe, the catback doesn't offer any performance gains, but now at stage 2, I'm guessing there is an increase in exhaust flow that might make a difference?
Thanks.
