Surprised I haven't seen anyone post about this just yet. Z1 released their new cat-back exhaust for the 07--13 Sedans.

Seems like a decent price now a days.

 

Someone on one of the facebook pages posted a sound clip and it sounds good.

Subtle at idle and aggressive at WOT. Kinda similar to my Top Speed setup with resonated y pipe.

 

What's the reasoning behind using a cast aluminum collector?

29 hp from a bolt-on catback on an untuned G37? Nope. That's some magical dyno they got there. However, it seems like a fine catback, and I like Z1 products.

I guess pricing has spiked in the last decade, because $1,700 doesn't seem like a bargain. You know, Fast Intentions' catback for the G Sedan is also $1,700, and FI is easily more top shelf than Z1. Also, Fast Intention claims 14 hp from their catback, which is honest and realistic.

 

They probably did cat-back with HFC/test pipe dyno, I agree there's no way they could gain 29hp from cat-back only. That's unheard of on these cars.

 

Head up as it looks like the new Z1 G37 Sedan Cat-Back Touring Exhaust is on sale now for $350 off.

 

Recently helped install one of these on a 12 g37x. Good build quality and fitment. Added a few resonators, but overall a good product I would say.

 

When I posted this comment the price was considerably cheaper. I don't think I'd pay this much for the Z1 exhaust. The prices of exhaust is pretty insane these days. Full motordyne is like $2200+? I got my full titanium exhaust for that much.

 

A casted collector lets you squeeze the best flowing merger with that design as well. Other than this they would have to be manually made which can be tricky and hit or miss in quality control, it also let's them utilize as a sales tactic.

Lastly the silent fart here is that it's tuned. Following social media many folks who are closer to Z1 or know folks personally involved have stated that it was tuned.

Disclosing this info upfront would kill it's sales.

 

Ehh I don't think it would kill sales to be honest. A 10-15hp gain would still be great for a CBE alone. I think it would kill sales more to claim 29HP because that's obviously bogus to anyone who knows anything about these cars.

 

Look at the 400 hp package.

Do you know how many owners of these kits actually believed it? Many believed it could be achieved without tuning, it seemed they were missing the W in the HP.
Then those that thought it could be achieved with tuning at least which was another let down.

The longer these items are purchased and owned will me better ratings and we are in the era of ratings as well. Folks dont like to waste money and many have removed these packages since they are copying some of the ingredients of the combo.

It's tough to survive as a big company in the Nissan world, nobody likes to over pay for anything especially when there was a bit of gaslighting by proper marketing. Giving folks ALL of the info will decrease these sales, Many found that Z1 ported manifold though CNC ported it has a light port vs what others offer at a competitive price. LTH have pulled some of the crowd that were buying their headers which since they are rasp prone they can play around with sound while making more power than Z1 ever did. Lastly their intake tubes are geared towards a safe approach that will make power without throwing things off however for their price there are some decent contenders out there.

When you start to compare apples to apples it depends what type of customer you are. There are many Z1 customers here however there are not so many "400hp package" owners. You do have folks here that try to mix the best of bolt-on possible. With this package the issue is that for sales purposes these power adders have to try to be the BEST in their category for them to not be passed on and this is why we are starting to see more and more unique parts from them.

 

Eventually, for some. Took me about 10 years to get where I was going.

 

Interesting and timely conversation as I'm thinking serious of doing exhaust this spring/summer. Z1's claim that their CBE was worth 28whp seemed off. Makes sense that requires an intake and tune as well.

I am thinking of going with the Z1 Y-back, if it goes on sale. $1300 seems a bit steep. But, if it goes on sale close to $1k, I'd be very tempted. The Top Speed Y-back can be had for $700, but the car sees plenty of winter and I worry about longevity of going cheap. My internal 18 year old is also tempted by the "I don't care what you think" style of the ISR single.....

 

Unsure why I feel like that exhaust could benefit from a bigger but longer resonator.

At the same time if the opportunity shows up to do single I would concentrate all efforts on that. Much simpler to quiet a single, even sexier when you go with a unique canister.

I feel like the Bazooka style canisters many choose when doing single doesnt look that good on the sedan bumper. Maybe a bigger canister with 1 or 2 newer style nissan/infiniti perforated tips.

Exhaust for me has always been about sound and power primarily, I'm going to have to live with it and going to hate my self if I **** it up.

 

​​​​​​​That's seriously misleading if the car got a tune to go with the exhaust too.
