Is everyone aware that the Magnaflow systems are guaranteed for the life of
the car......that of course is the pipe and welds not damage due to bottoming
out which is not their fault.

 

No prob. Hope it works for you.

 

just go to a local exhaust shop and get a 14" glasspack welded on and ur done.

 

Where could I put a 14" glasspack? After putting in the 14" Magnaflows, there's not even 8" of straight pipe anywhere on the entire exhaust - at least nowhere that has enough clearance for any type of muffler/resonator...

 

I have always wondered about that raspy sound!! With my stillen headers, race pipes and exhaust I have that rasp too. Pissed me off when I first got the whole system, so I sent the exhaust portion back to stillen, thinking there was something IN the res, or muffler somewhere. Same as you, it didn't go away. Thanks for this post guys, as usual, I learn something every time I log on!!!

 

Nice I have to give this wrap a try.

 

i think no resonators at all is best

 

Well I finally got around to wrapping my exhaust (thanks to Ballisticus' recommendation), and I figured I'd share my results with the group.

My overall exhuast note did not change much (at least I didn't notice any change). However, that annoying engine rattle around 3K RPM is almost completely gone now. I drove the car for an hour yesterday and was intently listening for it - but 90% of the time really couldn't hear it! The few times I did hear that "noise", it was so quick that it was barely discernible from the regular exhaust note! I consider this issue resolved now. Thanks again to Ballisticus.

Oh, I should also mention a few other things for those that may take on this project.

1. I bought 100' of 2" wide black thermal wrap (DEI from Advance Auto). I ended up using about 75' and, as you'll see from the pics below, got ample coverage all the way from the bottom of the cats to the H-joint.

2. I also decided to buy the DEI silicone sealant paint (made for this application), to protect the wrapping against the elements for as long as possible. I noticed driving home yesterday a strange "burning" type of odor and saw smoke coming from the wrap at a stoplight. I checked DEI's site and this is normal for a few days during the curing phase for the silicone sealant as it's baked onto the wrap.

3. Lasly, after a few hours of itchy skin and eyes and flushing black fibers out of my eyes/nose yesterday, I came to the conclusion that the DEI wrap must have had fiberglass in it. I verified that on their site later in the day. Unfortunately, I did not get proper ventilation under the car nor did I wear protective goggles or a breathing mask. Long story short, I was unknowlingly exposed to fiberglass dust for an hour or two. Lesson to others: make sure you research the materials in you wrap before going under unprotected.

In any event, hHere are some pics of my end result:

 

The trick in installing exhaust wrap is to soak in water then install it. Odviously let the material dry fully before driving. Installing the wrap this way makes for an itch-free install and a tighter wrap on the pipe.

 

I have read that one should careful when wrapping exhaust parts, more so headers. If you have cheapo piping the tape will hold in the heat it normally should give off. This increases the temp inside and causes the piping to disintegrate prematurely causing it to "rot" from the inside out. Can anyone confirm this or not?
