Hey guys i recently swapped my stock dp and cat with an ams dp and test pipe. ever since, ive noticed the turbo spool being WAY louder and much higher pitch. i thought i would get a little better spool from the extra flow, but just wanted to make sure what i was hearing was safe. i also have an aem short ram, and greddy rs bov

 

You intake makes turbo spool louder. If it sounds like a whistle, it might be a boost leak. Do a boost leak test.

 

Did you install your intake and bov at the same time as the exhaust or before?
The intake and bov will greatly increase the amount of sound of the spool

 

Yea you are fine. Just make sure you put the exhaust on tight so you dont have an exhaust leak. I wouldnt put the aem short ram on unless you are getting a flash or tuned. and in regards to the greddy rs bov, just make sure you recirculate back into the intake or you will have problems. have fun with the car!

 

i first had the intake installed over a year ago, then 6 months later did the cat back exhaust. after that did the downpipe and testpipe, then 2 weeks later the bov.
wierd thing is tho is im getting the same almost less sound out of the greddy bov then i was with the stock bov

 

In my opinion, that's a good thing. Nobody likes a ricer.
