Does anyone have PROOF that any of these aftermarket exhaust systems actually add anything close to what the manufacturers are claiming??

Discussion and Testing


NOTE THIS: "we strapped the car to a real dyno for the results. The Z picked up 3-4 ft-lbs of torque in the bottom end of the rev range and 2 HP towards redline. The numbers don’t sound all that impressive, but when you consider other systems have lost power, this exhaust looks pretty good. "

cincyspider, I've had the same thoughts as you. Nismo say's their cat back system is good for 6hp and 3.6 lb torque. BUT, right or wrong......I love the way it sounds!!!! I feel an exhaust change has more "smile" mod gains for the owner than HP gains. Just my 2 cents.

That car is at Mossy Nissan in Oceanside. I see that Z all the time when I go in for service. Also talked to Greg Vogal the guy in charge of the car. It's the Mossy Nissan Performance Z and it has allot of other goodies in it. He promised me a ride in it so I can give you all the downlow on the car. BTW it also has JWT pop charger, Nismo cams, Eibach springs, and soon(if not already) it will have Nismo headers. Greg told me that it put down 266whp on a recent dyno.

On a relevant note, both Borla and Injen have dynos out there that all show gains more than the B&B exhaust.

Baseline Dyno 243.0 HP and 230.9 Torque add one Borla True Dual and Dyno 241.3 HP and 230.7 Torque.

Happy with the sound and the look though.
Time to buck up for some FI.


...you can't see much detail in this Dyno, so you'll have to take my word for it.

A borla true dual does not negate HP... common.... r u serious about that chart, because there have been numerous post for 10+ gains

CarFanatic

hey cincyspider, check ot the regional forums trying to get a cincy meet togeather.

350z-to-be

On my baseline runs, there were differences of about the same amount (1-2 hp and torque) so I wouldn't really call it negating power, basically the same result before/after.

I posted the dyno conditions on another thread, but they were virtually identical, and the ambient temperature was actually a few degrees cooler on the Borla runs.... ...and my chart is 100% legit.

Again, the sound is worth the price in my books. I've read other threads where people were expecting more out of the Borla in terms of sound, but it's better than I expected.

243hp seems kinda high for a stock car. most people get about 230. may be something happened on your baseline test? 141 with borla is about right if your stock is about 130

350z-to-be

yeah, I thought I had the record for Baseline dyno, but was corrected on another thread. Someone's got around 252 hp stock, and I've now seen a few in the 248 range. I still think mine's better than average, but there are definitely some high ones out there.
I'm at a relatively high altitude (3,441 feet) myself and was suprised.

i want to dyno my car real bad. that will determin whether i will keep it for a long time and mod it, or keep it stock and sell it in a few years. 250hp wow! some people have to spend $2k to get it to 250. i better get more then 230 after my carefull breakin. never over 4k for 1200 miles. why does a 287hp car does 0-60 in 5.6-5.8 seconds? that seems about the average. it should be faster. i think nissan is full of s. i still love the way it feels and drives, but where is the power.

Mikestro

That article on Nissan Performance Mag web site sums it up pretty well.... The 350Z comes tuned extremely well from the factory. Mossay Nissan Oceanside only found 30 something HP with every mod available including cams.

This is why many of us already have or plan to have either a SC or TT on our Z's.

Don't expect much more than reliability from your break in style. It won't net more power.

and some people tend to think that driving hte car hard for the first few hundred miles gives you MORE HP in the long run (that is why they do it with race cars, etc......)

There was a link to a big/long post about it, I printed it out, but don't have it anymore.

It was written buy some guy who is involoved in racing motorcyles and cars I think.

zland

So what was the outcome of the article? Did he state that a hard break in = slightly more hp? My bet is no but I am open to find out what others think.

FLY BY Z

That's what I said. I think you thought I was talking to someone I wasn't. I should have quoted.

edit: oh wait I did quote up there! Someones not paying attention...

actually I am NOT sure if it was directly related to HP, BUT I know it wsa talking about future reliability. I think HP was mentioned, but not the focus of hte article

I know for a fact my car was beat on when I bought it, It had 50 miles on it and the salesman wanted me to beat on it during the test drive. Well, its been driven hard since, seeing redline way before 2000 miles and it was still around 230hp when I had it dynoed at around 4000 miles. Not sure if breakin has that much to do with hp, Some motors just run stronger.

350z-to-be

I've been treating mine like a rental since the day I got it and was curious if that's why my baseline was quite high, probably just the individual car though, good day at the factory, etc.,.

ZZZ-35

Engines are built to manufacturing tolerances and some engines get assembled with the perfect set of compoents to produce good power and torque and thats why there is a variation in the baseline dynos, this can be corrected by a good tunning shop it's called blueprinting.
