I've read at least 30 threads and watched 20+ youtube vids of various ISF exhausts and honestly, most sound 90% like the engine. So it's tough for me to tell which exhaust I'd prefer.
Basically I dig "meaty" and "deep aggressive". The 08+ STI exhaust from Perrin is hands-down the best I've ever heard/owned (on my '11 WRX -- my vid
). And I've been through a good 8-9 exhausts on the 2 Evo 8's I've owned. The Cobb ruled the roost there above Borla, Tanabe, Magnaflow, et al. But the Subie Cobb was no-question the best by far!
So I'm having trouble seeing much of a dif between the Joe Z and ISS on the interwebs. I have read that the ISS is louder or has drone on the hwy but I can't see/hear that from what has been posted.
Has anyone here tried or experienced both? Or even add the Borla full cat-back into the mix... I don't want drone...but really don't mind volume. But I've done intake/exhaust on every car I've owned but the ISF with it's "rarity" makes research difficult.
I like what I see with the light Ti Greddy but holy crap that's expensive! I'm in the < $2k installed ball-park. Sound is more important than weight and performance (this car has enough already) but whp gains are always welcome of course.
This is a 5l v8 so it needs to sing!
But not drone when I need to cruise with the wife.
I'm in the OC 92808 if anyone is nearby and would be up for me coming by to hear their setup! Drinks or lunch on me!
There is a gray ISF that lives literally next door to my grandparents-in-law(the Cozads) just off Fairview and the 405 and I noticed the ISS on that car if you're on here.
