Spent ALL day at the shop yesterday getting Sti up and Perrin catless dp installed with tune on my 05 GT.
It's a whole new car performance wise but there is no way I can handle the noise. It is way too loud in the cabin.
I was told there would be a throatier rumble but this is more than I can stand. This is my daily driver/family car and I feel like I made a huge mistake.
Is there any way to quite this down? If not I'm going to have to return to stock down pipe...I feel like an idiot.
