Stillen products are excellent quality and excellent fitment. As the saying goes, you get what you pay for. They also provide a solid warranty. Depending on what Stillen products you are talking about there may be a better product out there for that specific item but overall they make pretty good quality products.

 

Im actually very happy with my stillen catback exhaust. fitment was great and after it broke in, it sounds perfect. not loud and no rasp or drone. butt dyno said it helped as well.

 

I really like my Stillen CBE also. Just the right level for my taste and a nice tone with no rasp.

 

what where your gains cause i also have the stillen exhaust

 

I'm rocking Stillen sway bars on my car and love them..

Their Areo / Urethan parts are top notch and perfect fitment, I've had two of the Stillen splitters and their roof wing. All parts come ready to be painted and slapped on.

Their customer service rocks too, and I think their pricing is pretty reasonable... (I don't have any of their engine/exhaust mods)

 

I have the full exhaust and I love the look and sound, so that's preference for most people. Yea it was a bit expensive on the front end, but I had my dealer install it for me so I feel very comfortable with it. Also have the Stillen sways in there, honestly hard to tell the difference on the street and it made my car a little oversteer happy on the track (I was set too stiff in the rear). Just tried to install the rear window spoiler and it looks good, but the edges didn't want to stay down - just emailed Stillen to get some help.

Overall very happy with the brand, willing to pay a little extra to feel comfortable with the company I'm working with.

 

I want to install ultra long intake and high flow cats (Stillen) in my G37S.

Will it sound noise then? Will it be comfortable to drive in traffic and for everyday use of the car?
I'm worry about the comfort after installation .. The detailed feedback from Stillen users appreciated!

Thank you!

 

I just got the Stillen exhaust installed and I love it. For sound and horsepower. I'm no speed freak like some guys on here but I noticed the gains from the exhaust. People don't like the Stillen exhaust as much as the others because they don't feel like it's agressive enough. I disagree because we have to keep in mind the luxury elemnt of the G. The Stillen exhaust allows you to maintain that with a little more power and aggression,plus no fitment issues. As for the CAI, I have that coming too. I've heard enough good things about them. only downside is the fitment. There are some slight mods that will need to be performed in order for them to fit proprly
