Here’s another pull but with the invidia q300 catback installed, this exhaust sounds good under load and fixes a lot of things I didn’t like about daily driving with essentially a full straight pipe but this exhaust is very quiet when just cruising almost to the point you can’t hear the exhaust at all, I’ll drive with it for a few weeks and see if anything changes.
Grimmspeed UEL headers and up pipe, turbo XS Downpipe and tomei catback, I never realized how raspy the tomei is WOT especially right around 6500-7k rpm, I’m throwing the invidia q300 on this weekend to get the car quiet, the damn cold starts are brutal
I’ve got a 2014 hatchback Sti, I recently installed the Cobb fuel pressure regulator kit to fix the stumble around 3k rpm. After doing this I noticed a new tick/ tapping type sound inside the cabin coming from the engine bay but is not noticeable outside the vehicle or even standing next to the engine with the hood open. any of y’all had weird fuel system sounds after installing a new regulator? I kept the stock fuel rails but I do have ID1050s installed. Ive heard the Sti fuel systems are alittle weird and can make some pulsating type noises but not exactly sure if that’s true or not.
