Dude they are all pretty close. Just get the Berk... you will be happy with the quality and the sound. The extra power is just a plus. The sound is what you'll love about it.

PP numbers are more telling. 10whp over a 200whp baseline is 5PP, over a 300whp baseline it is 3.33...pp. basically takes the inflationary nature of dyno out, which does a lot to level the numbers.

I think he mentioned PP not WHP.
EDIT: he explained it

It's a percentage point gain.

The Greddy Turbo Ti-C will have no drone with the silencers in. It's a lot louder with them out and some drone right around 2800-3200 RPMs. 2.75" diameter pipes.

And gains about ~10whp/8tq with silencers with no turbo
It gains about ~7whp/4tq without silencers with no turbo

Pics of the fitment and quality here:

I'm real happy with mine. Sounds great inside and outside of the car. Looks good without being too big/showy. Fit perfect with no issues at all.

My TopSpeed exhaust has ZERO drone, and I even have the unresonted form. It also sounds great and its the cheapest ption by far

Well, I am hoping the effects of the Z06 are lasting. I gained...quite a bit from that 505bhp/3200#, lol. It really is a head-rush pulling up to a 427R Rousche and watching the person driving pointedly ignore you and move into the slow lane to let you by without even looking at you and making sure to do 5mph under your speed.

I don't want to be like that one guy who came in here telling us about how he was 6'3 and 230# and a big manly man and his friend told him over supper that the 370Z was a girls car and it ruined his whole night and he had to come and post up about it on the internet because manly men do that when upset by their friends insinuation that they lack manliness. I'll drive my 370Z with pride--rude supper guests not withstanding.

It IS a girls car..... they want to be seen getting in and out on the passenger side while you open the door, looks damn good on them

Just ordered Z1 post-maf hoses and K&N filters.

I have read the tests, and the K&N allows only 2% or so more crap in. If the OEM filter were within 2% of allowing enough contaminant in to destroy the motor, there would be issues. Everything has "design tolerance" and this falls easily inside that range. When I was in my 400 lvl statistics and research classes, they taught us about manipulating information via visual depiction, etc. Here is a perfect example:


Notice how the K&N is just shy of 97% efficient while the top filter listed is just shy of 100% efficient? A difference of THREE PERCENT is displayed graphically in a VERY slanted manner. Were this scale 0-100%, they would be a furry hair away from each other. Instead, the poster chose to use the top 4% of the 0-100% scale, and made the K&N graphic about 1/4 as large as the other. Very slanted, and I think it's a BS way of making your point.

This link explains the results of this man visiting K&N's facility 2 years later...
K&N air filter,,,,good or bad ????? - Page 3 - Nissan Frontier / Navara Forum

Having read this, it is obvious to me that Mr. Spicer is engaging in what I can "mental masturbation". It is fun, he has some data to back him, but in the end it is not going to bare any fruit of any import. 2-3% more dust is not going to lock your engine up and make the earth stop spinning. In fact, if you normally change your oil at 5K miles, and you then decide to change it at 4K miles instead, you will cut TWENTY PERCENT of the dust circulating in the oil. Not only that, but you will remove 20% of the time that that other 80% in the oil would have spent circulating. I wonder if Mr. Spicer uses 1,000 mile oil-change intervals on his street-driven vehicles?

Great point on the graphs.. we see this level of graphical manipulation...everywhere.. just watch your local news...
