I have been very pleased with my Stromung system. Having gone from stock to
Stromung, then back to stock (via sale of 95 avant and subsequent purchase
of a 95.5), I cannot stand the stock system. IMO the feedback you get when
you can hear/feel the car through the RPMs is very valuable. But it is not
so simple to get that sound just right, as some have discovered from
deleting cats, center mufflers, and making various other changes to the
stock system.
Previous Stromung generations had trans tunnel fit issues, as well as some
droning in certain RPM ranges. I have ridden in cars with these Gen 1 and 2
systems, and they are problematic. My system is Gen 3, and I have never
experienced any of those issues. I commend our man Posto for prodding
Stromung along to make improvements that benefit all future versions, I hope
he/they continue to do it. I would recommend this system to anyone
contemplating an after market exhaust system for a urS4/6.
While we're on that subject, (and this may have been brought up in the past)
would a flexible section (the large cross section braided stainless steel
looking thing you see sometimes used on Japanese OE exhaust systems)
incorporated into the the DP benefit the system by allowing some movement at
the DP/cat section joint (taking some stress of the welds)?
