I purchased a set of dynomax race bullet resonators for my stang. I went to an exhaust shop to make them installed, but they told me that this is too close from fuel tank. They show me what i ll look like, and yeah it seems very close. I would say less than an inch.
What do you think guys?

 

is that the only place they can be installed?? How long are the resonators?

 

According to my reads, Most people installed them under fuel tank before the rise of pipes.
Look like they don't have any problems, but it's hot here and i'm not a fire fan! Lol
Resonators lenght are about 16 inches with 4 inch diameter (chamber)

 

Here is a shot the Pypes Super System installed on my car. They fit and don't hit anything. I also have stiffer motor mounts so that might help.

 

Nice!
My resonators fits and don't rub anything, but i think the fuel tank is too close from the exhaust like your rh exhaust side.
Have you got a pic of clearance between your fuel tank and resonator?
