I want to put a better sounding exhaust on my B2, but don't want it to sound like the fart cans these kids are putting on thier tuner cars. And I would like to stay away from the ticked off bumble bee sound of a glass pack. Is there any way to achieve the throaty sound of a 4.0 out of a 2.9 or should I just live with what I have. Also if I install a test pipe will this improve performance, or will it kill my mileage with no power gain. I don't have emmisions testing where I live so I'm not worried about that. And last but not least what are some if any bolt on performance options for the 2.9? I already know of headers, hotter coil and wire set, and cold air intake, but are there any more tricks to tweak these little motors just a little more with out having a custom build job done? Thanks in advance.

 

Headers or no headers, even a custom Y-pipe or not, your best option(s) with cat and back replacement are 1) custom-fit high-flow cat and a high-flow 2 1/2" exhaust with a single in/out flowmaster or similar muffler and 2 1/2" pipe, or 2) high-flow cat and a single 2 1/2" in and dual 2 1/4" out flowmaster or similar muffler and 2 1/4" dual pipe exhaust. With headers, you'll probably get a more throaty sound and better low-end torque. With the high-flow cat, you'll get a little more gain. It all depends on how much you wish to spend on the exhaust.

As far as bolt-on performance, there isn't a whole lot out there, other than CamCraft cams, throttle body mods (the larger 2.9 throttle body from pre-88 or 89... or even a 5.0 throttle body with adapter plate), larger injectors, and if you want to spend the money, a performance chip (Jet and Hypertech). You can even go more extreme and go with an MSD Blaster EFI setup and get rid of your stock computer altogether, but it uses GM sensors as far as ECT, ACT, TPS, MAP, and O2 and you can also get the harness to plug into your TFI distributor as well as the 6-cylinder FI harness for the injectors. None of this is necessarily cheap, but it all depends on how much $$$ you are willing to spend. The one advantage of the MSD EFI setup is that you can use a laptop and software to tune it. This is something I recently found, although there are other aftermarket EFI setups that you can use, if I remember right. Again, all depends on how much you can afford and want to spend.

Sounds interesting has my curiosity up but I went to the website above to give it a look and was a little concerned.
I'd like to see a few more pictures of the exhaust on or off the truck or at least
a link that I could ask more questions before I shell out $250+ bucks.

I bought a book a while back....
How to Build and Modify
Ford 60 Degree V-6 Engines
By Sven Pruett
Motorbooks International
Powerpro Series published 1994.
covers 2.6 2.8 2.9 and 4.0
I think I got it from Amazon.com
Really interesting read and lots of info
Dave

 

Concerned? Why? Keep in mind the site is in development.

The exhaust looks factory as stated in the description on the website. More photos will be posted come spring time when we release the product.

 

I don't think I would try to market that to much more untill you speak to someone from DynoMax. I'm not trying to bust your nuggets, but I know of a person that got in a heap of trouble with Flowmaster over a similar situation modifying thier kits. They don't care what the customer does to it once they buy it, but to modify and try to resale, I think they may frown on. And what kind of warranty are you going to be able to offer on a modified prebent kit? Most of us that have B2's pick the muffler we want and just go to our fav exhaust shop and have a tail bent. I had my cat-back done with a Flo-tech muffler and 2 1/2 out and it sounds great and only cost me 97.50 with a 5 yr warranty from a local shop.

 

Did you go to the website? Somewhat unuasle wouldn't you say to not find any info other than one page even when you go to the other links.
Sounds a little fishy to me.
Dave

 

Dave - Did you read the above post????? I'M NOT DONE YET!!!!!

Quote from posting "Keep in mind the site is in development."

Nevermind guys, the world is obviously not ready to see the site yet until it is done.

Here is my website... www.FrostHeater.com

 

The H or Y pipe, now the 86 and 87 2.9's had an advantage in that they have an H-pipe rather than a Y-pipe like the 88 and later do, meaning that with an 86 or 87 h-pipe you can run full duals while this is impossible with the later 88 and up y-pipe. therefore the 86-87 h-pipe is the more desirable one to have, but depending on your emissions situation you may be forced to run the y-pipe with an 88 and up 2.9.

 

86 y-pipe

 

Tbolt
Thats a good looking truck
2 questions, what size spare is that, I got a tire cover but I have 31's on the truck which that cover will not fit and by the time I got a spare the right size I figured it would be like using one of those space savers.
The other question is what kind of driveshaft is that.
Dave

 

Nice looking truck, and I like the tasteful exhaust.

For those who just want a super simple bolt up cat-back system, the H-pipe would be alot of work.

 

I'm not selling Dynomax kits...Dynomax sells Dynomax kits. I'm selling a custom exhaust that happens to use their muffler. They will be happy with the additional sales of their muffler.

I'd be willing to bet the exhaust will outlast the truck....these B2s haven't been made in almost 20 years.

Sounds like you wasted alot of time when you could have installed our kit in the time it took you drive over to the exhaust shop. How about the hangers? How about the clamps? Plus, you don't have the mandrel bent pipe and cool stainless steel tip.

 

Well, this wouldn't be for everyone, but, what I did was put a 2" body lift on the BII, ran true 2" dual exhaust with a pipe on the left and right and I came out between the rear bumper and tailgate. I just cut the plastic valance to clear the exhaust. I ran the pipes so they just barely intruded into the wheelwells.

I did this so I wouldn't take my exhaust off backing into something such as a log and because I wanted to make my B2 capable of crossing deeper water/streams after I drowned it once.

I think I used Thrust? purple glass packs because they were the skinnest. I put the exhaust together with three bolt flanges so I could easily change a muffler or test pipe.

I took the OEM bung from the H cross over and welded it to the right pipe.

The biggest performance boost with the 2.9L/auto was taking up all the slack at the gas pedal.

 

OK,
I apologize I'm just a little skeptical about new stuff and when someone sends me to someplace to view a probuct and don't find a lot of info.
Its that "Once bitten twice shy" thing. Been bit too many times.\

How much would this kit be for a 90 BII 2.9 shipped to MD 21157?
