The result of IPD Plenum + Exhaust
At idle is the sound is very nice and deep and fairly quiet. Stuttgart performance has done an awome job. I asked Mike (my pal there) to drive it on the street while I stand by outside. OMG when he drove by me while on boost, the car sounded like a furious demon, I just loved it.
The people at Stuttgart are the best, nice,informative, knowledgeable and reasonable. Anthony worked on my car personally, he is awsome, always nice and friendly.
Bottom line the plenum + exhaust makes the car quicker and torquier and more responsive at all rpm's vs. stock. My advice to you all DO IT
I drove the car for 3-4 hours and in all honesty I was ready to give myself and the car a break so I went home and tried to make up another story, telling the wife that I did not spend that much $$$ today
