Hi guys, so today I got my grimmspeed catless up pipe installed and I was surprised because now my car is quite a bit louder, you can really hear it rumble now.
The only mod I had before that was a perrin catless downpipe, i still have the oem catback on it.
I was expected to hear a louder turbo spool but not the rumble in general?
I had a reputable subaru shop install the up pipe for me because I was not confident enough to do it myself.
Is this normal or do I have an exhaust leak?
The car is tuned, no CELs or anything
