SLP 2 out the left exhaust

My dad's old thirdgen had one of these systems... it was an SLP 2 out the left (2OTL) exhaust. Basically, the muffler had two tips exiting the leftside of the muffler and they dumped side-by-side under the rear bumper on the driver's side. It gave the car a classy look and the mufflers sounded great to boot.

I know SLP discontinued these, but does anybody else make something similar? Anybody still running one of these? I may have to have one fabricated with an SLP or Magnaflow muffler. I really like the subtle, hidden look with the twin dumps.

Here's a pic of a system that I found:

Re: SLP 2 out the left exhaust

im going to make my own.. which is pretty much your only option unless you can find one used.

you can use a Magnaflow 3" in 2 1/2" dual out... forgot the part number right now, but its the same size and length.. then just make up the elbow's for the pipes.. pretty easy

Re: SLP 2 out the left exhaust

id make my own too, heck any muffler that has a tone you like that is a single in dual out would work great for you..... you aint got to worry about getting a cross flow.

idk if you heard me talking about it sunday but since i had to hack my exhaust to heck pulling the tank, im in need of a new muffler now, i been thinking about the cherry bomb vortex cross flow for mine. I just want to have the exhaust hidden with just two turn downs dumping under the bumper

Re: SLP 2 out the left exhaust

I too have a 2OTL exhaust and high flow cat for sale, it's a Dynomax setup though (they had all the parts to make one just didn't list it as a kit. It's a 3" inlet with 2 2.5" outlets). Hardly an hour on it, just installed it while tuning the motor. I took it off and packed it up when I sold the car some years ago.

If anyone's interested PM me for details.

Re: SLP 2 out the left exhaust

These systems are easy to make from existing parts.

You need the following, a good condition i-pipe with the over the axle pipe in decent shape. 3" ID better than stock.

a Single 3" in, dual 2" out muffler (your brand choice), and the two exhaust tips. Hooker and Borla make one. Flowmaster and a few others probably do too.

And someone to make the 2.5" exit pipes from the muffler, bend them, and make them tuck right.

Now, I have a 2otL cat-back, but I'll probably be replacing the muffler with a 3" single in, dual 2.5" out Hooker Aerochamber. But there are many other mufflers I could choose from.

Any exhaust shop should be able to assemble something like this.

If you already have a 3" I-pipe from a cat-back on your car then you can simply adapt that and replace the muffler down with a 2otL system.

I love the way it sounds on my current LT1 swap. http://www.youtube.com/watch?v=1c9j2Kg43c4
