240SX ISIS Straight Through Race Exhaust Install and Review

I recently bought ISIS’s new 3in Straight Through Race Exhaust. This exhaust has no mufflers or resonators and is 3 inches straight through that splits into two 3 inch outlets at the axels. The wide open design is great for a turbo set-up and works fine for na KA.

Installation of the exhaust is unbolt, un-hang, bolt and hang. Everything went smoothly and was as straight forward as it gets. I suggest you get new rubber hangers if you are installing it on an older car because the stock ones are probably worn out and stretched causing the exhaust to hang low.

So you know, I have a header and test pipe in front of this exhaust. After I got it on, I fired it up and it is significantly louder than my previous dual n1 style exhaust. The sound is raw, loud, ridiculous, and awesome all at once. It’s loud, yet still sounds good. Driving around at low rpms it’s loud yet you can deal with it. At high rpms hell opens up as you trumpet forward. If you want and exhaust that is no-nonsense and raw, this is it!

Installation:

Tools needed:

Ratchet
17mm short and deep well sockets
17mm box end wrench
Shampoo/soap (I’ll explain in a minute)
PB Blaster

Step one: Raise and support the vehicle safely on jack stands.

Step two: For those of you replacing stock exhausts, spray down the bolts with some PB Blaster to make life easier when you start to unbolt the exhaust.

Step three: Unbolt the exhaust from the catalytic converter, or test pipe in my case.

Step four: Using soap or shampoo soap up the stock hangers to make removing them MUCH easier. There is a hanger off the back of the trans (I removed mine previously), one just before the axels, one after the diff, and two near the bumper. Remove the hangers from the rubber.

Boo Michigan rust.

Step five: Remove old exhaust.

Step six: Bolt up the first half of the exhaust.

Step seven: Soap up the hanger and slide it into the rubber support.

Step eight: Bolt up second half of the exhaust.

Step 9: Soap up the hangers and slide them into the rubber supports.

Installed:

Here is a sound clip of the exhaust from idle to about 3,000 rpms:
