My order finally arrived from ninosports.com – So, I installed my IMCO Performance Exhaust today.
They cost me around $330 including shipping.
So here is how it went.
The system was an Axel Back, so installation was pretty easy.
Here is now they looked out of the box. They came with a new clamp and simple instructions.
.
First – You have to loosen the tie-clamp behind the H pipe… This requires a 15MM Socket and a screwdriver. You have to loosen the slide clamp to disengage the pipe sections by sliding the clamp back onto the exhaust pipes..
.
Note – there is a spring clip on top of each slide clamp, that hooks behind the retainer/alignment pin, which you have to open with a screwdriver in order to slide the clamp onto the exhaust pipes to disengage the pipe sections.
.
I used a Bungee cord to hold the pipes up while I was working on the back half.
.
Use the 15MM socket to open the clamp holding the Factory Muffler onto the tail pipe. The clamp is welded to the muffler; so do not try to actually remove the clamp.
With a little twisting and yanking, the muffler actually comes off pretty easily.
Twist the tail pipes out of the way.
Put the new mufflers up by their hangers… then mate the tailpipe to the muffler and finger tighten the new clamps – you will need a 9/16” socket for these.
Re-aligned the H-Pipe slides and lightly tighten the clamps. Be SURE to make the spring clips hook on the other side of the alignment pin.
Move stuff around until you like how everything looks! Then tighten the mufflers first. Then the H-Pipe slides.
Remember to recheck all your connections and re-tighten everything after 50/75 miles.
I love the sound from these things - - Nearly exactly like the sound of Steve McQueens 68 Stang in the movie Bullet. The idle is a VERY low grumble. The sound at WOT just makes you want to do it MORE!
Because I have an automatic I went with the “Pro Series” because of a “Drone Warning” that IMCO put out about the “Extreme Series”. Those of you with manuals will want the “Extreme Series”. They sound the same, except, the Extreme is a little louder and a slightly higher tone.
There IS a bit of a drone at 1800 to 2100 RPM with mine, but it isn’t all that annoying.
