fox exhaust setup
 

hey guys
I'm currently putting a 1987 coupe on the road and wanted to get some great sound and power out of her as I dont need to do an emmission test.
I was thinking bbk shorty headers, stock h pipe with one or both sets of cats punched and flowmaster 40 series mufflers. I'm thinking of using this setup because the components are cheap and easy to source used.
I'm just getting into the mustangs and would appreciate any suggestions regarding my plans from the experienced members
Also I was thinking of putting 3:55 gears in

I'm assuming its a 5.0 we're working with? Also, 5-speed or auto?

I would go with long tube headers and an off road h pipe. The 40's will sound great.

sorry, yes its a 5.0 standard

i heard that long tubes will give me problems ie: starter and modifications to install? and would a stock h pipe with hollowed cats do the same as a off road pipe? (so the cops dont bug me)

Long tubes are pretty comon on those cars so I don't think you should have any issues they just fit a little tighter. An aftermarket mid pipe will flow much better than your factory one.

I have a mac offroad H pipe for longtubes, a pair of magnaflow mufflers amd flowtubes for sale. can still be heard on car but not for too much longer

I have no doubt the 40's will sound great as I had them back in the day

With a 5.0, 5-speed ... I'd go with 3.73 gears rather than 3.55. I think you'll be dissappointed with the 3.55's.

x 2 on the 40 series ... you'll like the sound.

Long tube headers are a great suggestion BUT if you're not installing them yourself I'd get an installation quote BEFORE you buy. They can be quite the job to install and the cost of installation reflects that.

Good luck. Let us know what you went with.

So i want to go with 3:73's?
I can only go with what advice I recieve as my experience with these cars is limited.
I'm thinking i'll go with shortys as they seem to be easy to find used and can be installed with ease, I really just want to make her sound mean and take advantage of not having to do an emmission test

I had 3.73 in my 89 coupe and they worked great.

Are shortie headers a good idea boys and what's the benefit if any?

They flow better than the stockers but not as good as long tubes.

so would an amateur like myself be able to install longtubes?
does the motor need to be moved to fit them in?

Thanks to everyone for all the input thusfar by the way!!

no expert but on the 99 on up I hear they are a booger to install. I am sure someone will answer you quickly

It's much easier on a fox car than anything newer but it's still not a simple task.

They are a easy install on a fox, you will have to bypass your air pump tubes and plug it off at the back of the heads. 4:10's will give you what you want unless you have a blower

3.73's then ^^^^

So no loosening of motor mounts?
I have a set of 4:10's in a parts car but im told that they are hard on the car and will make it hard to drive

You have losen the motor mounts and jack up the engine to install long tube headers, in some cases you have to remove the starter.

^^^lots of work

yeah.lol. if you don't want all the work,go with equal length headers and high flow h-pipe

what would the time difference be?

I installed mac equal length headers back in the day,put car on jack stands and intalled headers from the top with no problems. took 3.5 hours. Now have long tubes

^^^thanks

Thanks for all the info guys!
I think i'm going to go with long tubes, i'll keep everyone posted

excellent and thanks for any updates

long tubes is the way to go.

well i bought a set of mac long tubes and a pro chamber x pipe for $220 once i get time to finish putting her together i'll install the exhaust

it will sound great with a pair of flowmaster 40s, 2 chamber mufflers

video's are great lol

yeah, you're right.

Okay so i've installed the long tubes, pro chamber x pipe and 2 chamber flowmasters and she sounds amazing!!!
I cant seem to upload a video? im working on it and will keep you guys posted

glad you're happy dreo.

thanks for the advice!

Hey guys
After driving the car around for a while I've noticed that it feels a little sluggish, the best way to describe it is it doesn't feel as crisp as it should.
I was told it may need a high flow intake or a new distributer and coil or both, what do you guys suggest?

check your airfilter first could be clogged, a new upper and lower intake would also be a big help in performance. stock e7 heads flow better then the stock upper and lower intake. you can get a nice cobra one online for around 540

so my car is not getting enough air?
if i do an upper and lower intake do i need to change my throttle body?

I would

yes also the stock mass air meter is the size of a quarter lol. if you buy a throttle body dont go bigger then 65mm, 5.0s lose power with any bigger TB unless it has a power adde.r
