Chances are yours did not come with a 20" spare, the easiset way to find out is to lay on your back under the rear bumper and look at the tire.

I say go for it just keep an eye on the tire clearance from time to time.

 

what was the outcome of this?

 

Man someone always wants a story.

This time I had no problems with a tire fire. I did however forget to set my Edge back to stock so running level 2 I had no trouble, this time I drove around 70-72 mph as opposed to 60-65 mph last trip.
I also replaced my 18" spare with a 17" spare which gave a little more clearance and I wrapped more heat tape on the exhaust pipe near the tire, now its double the thickness.

In short I had no problems this time but it has cost me considerably in time, money and aggravation. This is something that should not have happened in the first place.

 

Maybe its just me, but I read through all this, and while I agree with Welfare that burning spares every time he tows a trailer SUCKS...I cant believe he hasn't done the most obvious thing that MGD suggested...just take a damn temperature reading to determine if its your tune- or- cheaper than buying two spares, why didnt you just relocate the tail pipe? Any local Meineke shop can do that easily enough.

If it were happening to me, I wouldnt be calling out Magnaflow

 

I thought that these exhaust's where like (Windows) just plug n play. Correct me if Im wrong but isnt the 16612 a direct replacement of stock exhaust? If so why will I need to bend or shift it for clearance. Shouldnt it just align in the same position that the stock was in? Please forgive me for all the questions. Yes I am a newb when it comes to this and I would like as much information that I can get.

 

First of all can anyone tell me where to buy and how much a temp. device cost?

Second I did visit a muffler shop, they told me everything looked fine, thats how they would let it out the door if they installed it themselves.

Third I posted that I have tried to contact MF. I emailed them twice about the situation and get a generic response about how I should look over the FAQ section to see if that answers my question,if not they will get to me sometime.

Forth Magaflow Rep has spoken about the issue and tells me to relocate my spare which I have done and it vibrates back to original postion after driving a bit.

 

No problem, I too asked many questions before buying one myself, according to the instructions I had enough clearance around my spare. The local muffler shop backed me up on that issue.

 

Optical pyrometer's will give you a quick check of the temp or at least the pipe temp. They are cheap enough. I think radio shack may even have them. Try searching google for a EGT sensor if you want to go that route. I'm sure you'll find all sorts of options.

FWIW, email is not the way to address a concern like this. Call them and ask to speak with engineering. Email is too casual and doesn't send the right message.

 

I have never just bolted anything on any car and not had to make some adjustments. Nothing i ever buy seems to fit just the way i like it without some tweaking on some level. However, his exhaust should not be setting his spare tire on fire...

 

Even when he's towing? What amount of weight would you guys say is too much for towing when you have this exhaust installed.

 

NO the 20'' spare only comes with the HD/Limited Editions. The stock tires are normally +1's to the spare.

XLT w/ 18''s = 17'' Spare
FX2 w/ 20''s = 18'' Spare
HD/Lmtd w/ 22''s = 20'' Spare

 

pmason, yea I don't think anything I've added fit (exactly) perfect at first. Even if it fit well usually it could be tweaked. I'm sure many kits will just bolt right up but wouldn't bet on any system fitting absolutely perfect without giving it a good once over. You can pull until your tranny falls out with proper clearance.

 

I have the 16612 installed on my Screw and I also have the 18" wheels. I have towed 5-8000 lbs for a total of about 15,000KM in the past 10 months with the exhaust on and have not had a problem. There is about 1.5" of clearance between the pipe and tire.

I once pulled a 30' trailer with 4 compact utility tractors and attachments with the total weight being 9600 lbs (verified on the scale and yes, I know too much weight for the truck... ) for 350km into a really strong head wind. The truck was working hard that day and my spare is still fine.

I think MGDFan is on to something with you truck not quite running right to generate that much heat. Towing and the Magnaflow exhaust should not cause this to happen.

 

Could a muffler shop fab a sort of heat shield around the exhaust going next to your spare?

I know this is not a perfect solution but...

 

My Roush Off Road won't be setting my spare on fire. They designed the system right the first time.



Magnaflow needs to fix this design flaw.
