Review: Stillen Catback Exhaust

mpp9 · 10-08-2009, 05:00 PM

The new invidia gemini seems to limit rasp with new dual mufflers. Stillen and F.I. seem to be pretty well documented at close to 20 whp. Can anyone say if the invidia would be around the same? I've only seen the manufacturer dyno not an independent. Plus amplified is offering the invidia for hundreds less than the stillen and f.i..

I almost picture BBs rattling around in a tin can. That type of sound. Is that what you guys mean as well?

Tinny BB sound = rasp. Some of the early fitments had rubbing issues that were fixable. I have the Stillen CAI, CBE and HFC. I had a bit of rasp when it was cold when I first had them installed but once the exhaust had been heat cycled several times the rasp is gone. Every exhaust system I've ever had need at least 1000 miles or more to "seatle" in/blow out glass, etc. I think personally with just the CBE would be too mellow for me and that was my main concern with the Stillen - performance gain is excellent but its fairly quiet. With the HFC it sounds fantastic and I get endless compliments on the exhaust. Not only that but people constantly are asking me were you at so-and-so at such-and-such a time. I'll say yes and they'll tell me "oh I thought that was you - I heard your car driving by". I even get friends texting me telling me they heard me drive by "damn that thing sounds sweet", etc. This is a well loved exhaust note! I get compliments from the R8, Porsche, Lambo, Ferrari, etc, etc ,etc drivers all the time. Next to the looks of the car that's the most commented item on the car.

I'm happy with it 8)

does anyone know if the stillen exhaust is 50 state legal?

Looking for some assistance here. Installed Stillen Catback Exhaust today and now have the dreaded "Service Engine Soon" light. Is this something that resulted from the ECU learning the new configuration or is it possible I have an actual problem?

If it helps I also installed the Stillen Gen 3 Long tube intake this week.

The catback shouldnt trigger a CEL. I'd just reset it and see if it comes back...it shouldnt.

To my knowledge neither of those should trigger the CEL, so I agree with RCZ, do the reset and see if it goes away.

I'd look over your Gen III intake install and make sure you didn't damage a sensor or have one mispositioned. The catback isn't the culprit.

You could always just plug a code reader into your OBDII port to see what the code is. If you don't have one, you can stop by any auto store like AutoZone or wherever and they'll do it for free.

You never mentioned the unsitely look of the muffler hanging down unlike the stock muffler not to mention the loss of groung clearance, or the additional 18 wheeled horsepower that stillen states the muffler system offers you.

Because it's not unsitely. I keep mine polished and I always get compliments about it. Trust me the people making comments are more than happy to let you know if they don't like something...

I've NEVER tagged anything on the muffler and I'm ridding on Swift springs. I've scrapped the front lip plenty of times and even caught the exhaust flange (my own fault - never on large speed bumps, etc) but never the muffler...

Just as a note, there is NO rasp with the Stillen CBE alone.

.... with FricFrac

I enjoy and never tire of the Stillen CBE sound, it just seems to sound better the more I drive the car, in fact l look forward to it every time I turn the car on!

I have a 2103 370 touring sport with the Stillen Catback and Gen 3 intakes. Got to say it was all a easy fit and looks amazing and when I go a show all I here is that my exhaust sounds better then what they have. Stillen products are very well build and had no problems with fit and the final look....
