I just installed the joe z cat back system on my car and there's a nice deep sound from jump! I've only heard the ark via youtube and it's quite loud when revving through the band; joe z isn't a joke either. now I've heard the joe z cat back system on youtube or instagram as well and hearing it live is definitely not the same. some say these exhausts get louder (or something to the sort) after it gets broken in. if that's the case, my wife is going to hate riding in my car...haha. the joe z sounds nothing like a fart can and sounds nice throughout the cabin as well. I have yet to hear the ark live, but I don't think they're too much different.

Just ordered the ark based on One thing. Its growl on a cold start. Based from the youtube videos, sounds like youve just awaken the monster.
also those resonators are the nuts. Makes exhaust look so much more clean.

Bringing it back from the dead. But I've tried searching for JoeZ's dyno and found nothing. Anyone have info if it makes power or not? Considering that Ark is 2.5in and JoeZ is 2.25 there should be better gains with Ark IMO. I've asked JoeZ why he didn't go 2.5 and no definite answer ¯\_(ツ)_/¯

Who cares about dynos anywho? If you are really concerned about horsepower and making your car a tuner, you shouldn't have picked a Lexus IS. I find it somewhat laughable seeing GTHaus exhausts on IS250's... The loudest possible exhaust for one of Lexus's slowest cars. Cool I guess. If that's what you like. And that is EXACTLY what this platform is for all of us, a personal preference crap. Like a shiny tube in your engine? Get an injen intake! Want track quality brakes when the car will probably never see a track? Get some brembo rotors and calipers! Want to sound a little louder? Get an exhaust! Get an exhaust that has the tone you like! Because there is going to be close to no difference which catback you decide to go for as far as "performance" is concerned. Just take tone and price into consideration and worry not about dyno's. Trust me, you will be a much happier Lexus IS owner.

Also the definitive answer was 2.5" piping is too large on a full true dual exhaust on a V6 motor..
2.25" piping is the correct size for measurable performance..
We properly use the 2.5" piping for our V8 exhaust platforms which include the IS F, RC F and soon GS F..
Hope this helps clarify your questions

What I don't get is that both systems put out pretty much the same HP so in theory, does that mean 2.5 and 2.25in is neither good or bad? Believe me I'm a full believer in the PTS system, I've had it on my 06 and it was thee #1 exhaust IMO.
I'm just trying to see what would benefit my SC later...
