MAP (minimum advertised price) on it is $1350 ....but people can choose to sell it for less then that if they wish.
Also we have a lifetime warranty- and with our warranty if any weld breaks, any hanger breaks, we dont just replace the part...we send out an entire new kit.
So far I am really happy- have put 80 miles on car with kit - no drone on the highway...
Only part that sucks is that the car all ready had intake/exhaust on it so dyno results dont mean much...as they are not showing gains over stock, they are showing gains over a competitors axle back....
Which is long as I am typing I thought I would offer some tech as well....
What makes more power- intakes or exhaust?
actually whichever one you install first : )
New cars have parameters within which they operate- adding an intake or exhaust causes the computer to move towards one side of that parameter....but once it approached the outer parameter, you can not move it any further without custom tuning.
So while an exhaust company might advertise certain gains, if you install such exhaust on a car that all ready has an intake on it- well the intake would have all ready forced the computer to take advantage of any play within the parameters so by installing the exhaust, there is not enough room left within those parameters to see the same advertised gains
This is why if an intake is 10hp gain and an exhaust is 10hp gain- when installed together they dont make 30hp ...typically whichever one is installed first will see the full 10hp gain- with whichever one is installed second only seeing a fraction of the advertised gain...
Its why I hate dyno sheets- because actual results vary depending on how many mods you all ready have : )

Can anybody tell me if I can replace my Exaust System on my very loud G37 ??
It sounds like a Mack truck at 1000rpm and above.
What a pity !!! I was under impression It was a luxory sedan when I purchased it new last year, now I know it's only a noise maker...
Please anybody Help......
Thanks

No one has said it on here, but there are alot of people that hate on the Magnaflow exhaust. I am not sure why, but maybe because it is lower priced than other 'premium' exhausts, or maybe because people have the misconception that they are 'made' for American muscle cars. I had a Magnaflow catback system with AMS HFCs on my EVO X. It had a nice deep rumble at idle and wasn't that loud until you got on it. It definitely sounded great at WOT though

My tips are Magnaflow, and I got quite a lot of negative opinions that they look too domestic, belonging on a Mustang, not an imported sport sedan. So yeah, it would seem market opinions of Magnaflow are more aligned with trucks and American muclecars.
But I don't care. A good product is a good product, regardless of perceived associations.
There's your problem right there.

I would possibly go this route, if I had the funds. ARK would be my other choice.

EVERYONE. performance Peddler is selling this thing for wayyyy below MSRP, like sub $1000. im not going to link to it, but if you type in the product number 16862 on their page, then "make and offer" on the side of the product page, it will give you a coupon code to get the special price. i bought a magnaflow system from them for my 03 stang and it came super fast.

And thank you for all the comments from everyone else!
You know what the funny part is- We make the exhaust systems for many of the well known "Non American" name brands- of course we are under a confidentiality clause so I can't say for whom....but we do make some parts for some very well known and respected names in the Nissan community...
Very suprising for all the exhaust companies out there, there are actually very few exhaust manufacturers.
One of the main reasons I never bad mouth another brand- if we are not all ready making parts for them....one day we could be!

I went through the process as you stated and entered a "1" in the make offer box and BINGO, what a deal. If I didn't already have an exhaust I'd already have it on the way, and for that deal I'm still considering it!
