I was browsing magnaflow's website and ran across this
http://www.magnaflow.com/02product/shopexd.asp?zone=Trucks&id=912
and a dyno graph that says it will add +12 hp and +14tq to the wheels. That is quite a lot of power compared with the gibson that reverendbiker installed and reviewed for us. I was amazed at the gains that their truck produced and how high the stock numbers were (compared with K&N's base numbers and reverendbiker's numbers).
So I contacted magnaflow about the exhaust system that they are going to release and this was the response so far.

I saw on you website that your company is making an exhaust kit for the 2005 4.0L V6 frontier. I had a few questions about it.
1. Is it available for retail purchase yet?
2. How much is the retail price?
3. Is the dyno graph using a completely stock frontier with the 4.0L V6 or does it have an intake? It the test truck an automatic or manual transmission?
4. Does it come with a new y-shaped pipe after the cats and before the muffler?
5. Is the whole system stainless steel?
6. Is it a side exit single tip system?
7. Does it compromise ground clearence?
8. Will it fit a 4wd king cab std bed?
9. Is the exhaust system significantly louder than stock (any drone in the cab at cruising speeds)?
Thanks in advanced for answering all the questions to the best of your ability.

Thanks for the info...

I too had seen the preliminary info on Magnaflow's web site and wondered when more would be available. I'm planning on an exhaust upgrade shortly so this is timely information. Thanks again.

I have had good success with Magnaflow products, but I don't believe for a minute that their system will add 12 HP (rear wheel) and 14 TQ to an otherwise stock truck. I've done dyno tests on exhaust systems for several years, and have seen independent tests done by other owners; horsepower claims made by manufacturers are usually inflated outrageously.

I agree with that. It was just amazing to see that they would put such a claim even though their exhuast system is not even in production. I am actually waiting for borla my-self, but if borla doesn't make something soon I will probably go with magnaflow. Btw how do you like your gibson cat-back as far as long term goes.

I am still pleased with the Gibson system, but I still believe that other owners would do as well by just going with an aftermarket muffler; the small power gains won't justify the expense for most folks. I love the sound of the Gibson, and I like the fact that it's really quiet at highway speeds. Long-term? Long-term truck ownership for me is 2-3 years, so a stainless steel system is really a waste of money in my case.

i just recieved my magnaflow exhaust system, looks great, full stainless, side exit, looks great and all, but it requires cutting of the stock system, but theres a box looks like a ground but im not sure, welded to the tailpipe near the axle, and i was curious if anyone else sees this or is it just part of the Nismo package? do i need to weld this back on to the new tailpipe? i didnt want to have to cut anythign but it looks like i have to regardless of the exhaust i chose ... anyone whos also recieved or installed the magnaflow exhauts for the 05 please let me know, thanks!

Where are they requireing you to cut the stock system? I know for a fact that both the Gibson and Banks systems available for our truck is a straight bolt on system, no cutting required. Not sure what you mean by the "box", I have a NISMO, I guess I need to check my stock system which is being stored in my shed to see what your talking about. BTW, does the Magnaflow system include a new "Y" pipe? I know both the Gibson and Banks do (I have the Banks System), and after removing the stock system and examining the stock "Y" pipe you can see it's a major point of restriction! Looks like the crimp both 2 1/2" head pipes and cram them into one 2 1/2" pipe that connects to the muffler. Gibson and Banks use a large two into one collector to accomplish this job! Post pics if you can!

got it installed today, sounds really awsome, was kinda dissapointed i had to cut the stock system, no new y-pipe, and the "box" i saw was i guess just a ground .. but easily reattached .. yeah you had to cut the stock pipe 1" from the front face of the muffler .. all that came in the package was the new muffler and tailpipe .. but id say it was worth it if your lookin for a badass sound and a lil more pickup .. deffinatly worth the install in my opinion (as long as you have the right tools) ... kinda wish it were a bolt on, but ehh whatever .. it works either way, and tis not ghetto-rigged either .. so its all good. altho its good to knwo if anythign were to go wrong i could always goto banks or gibson for help! hah ill post pics and sound clips as soon as i can get my camera workin again!!!

That's pretty crappy if you are required to cut the stock system to install the Magnaflow. Why the heck wouldn't they include a new Y pipe? Looks like I'm going with the Banks when I get the $$$...

So if I'm reading this correctly, wouldnt this setup be the same as getting a magnaflow muffler welded in place of the stock one? I'm cosidering getting a new magnaflow muffler, but I was quoted $89 installed at a local muffler shop. I considered a FM 40 series, but the muffler guy recommended Magnaflow for a v6. Got any sound clips by chance?

If anyone is interested, I'm planning on taking my Banks system off my truck. It's still too loud for my taste! It's only been on the truck 2 months. I'ts a complete bolt on stainless steel system, no cutting required.

Army,

Sorry, it's gone! It came off Saturday and I sold it Monday! I guess you have to be pretty quick on these boards!

I'm thinking of doing the reverse Magnaflow upgrade, that would be cutting the stock system just before the muffler and replacing the head pipes and the "Y" with 2.5" pipes going into a free flowing two into one collector and then using the stock muffler and tiap pipe that are already 2.5". I should get a freer flowing system while maintaining the stock sound level!

Could it be they are really enjoying the new sound and therefore mashing the accelerator more? :eek:

I have the magnaflow 16628 and love it

I have the magnaflow too and love it, they are cheaper on ebay but I wanted a warranty (the salt on the roads here in winter kills an exhaust) in case somebody's interested I got it here magnaflow 16628, or you can try one of the vendors here, they are always running sales/specials. either way its a great system and very easy to install.
