My 96 SS Convertible has the original SLP 2OTS catback behind Pacesetter long tubes and Y pipe. Engine is upgraded too. Overall it's making too much noise. It's overkill for me, senseless chaos coming out the exhaust whenever I touch the gas pedal.

I need a cheap easy solution to silence the chaos and leave the clean V8 sound it should be making. What can be done?

I've asked SLP and they say there are no more 2OTS mufflers. Mine is probably burned inside it acts like a resonating chamber.

Help?

 

Such a bummer.

I'd probably just throw a resonator or high flow cat on it, but then again I love the sound of the SLP 2OTL. I'm not sure what other catbacks are quieter than the 2otl and flow equally or better. The 2OTL is relatively quiet for how well it flows. It looks like SLP still sells the dual/dual (2.5in, dual 2.5 out) that could be fabbed up but you'd be choking the exhaust down to 2.5" before the muffler vs. 3" with the 2OTL which would make it quieter and hurt exhaust flow.

I'm in the process of swapping out my shortys to Pacesetter LT's.. but I want a little more grumble.

 

The SLP dual/dual muffler is quieter and flows almost as well. I only use the 2OTL and dual/dual catbacks on my cars

 

You could do what they did for the early '97 SS's, and stick a cone of silence in the muffler entrance. A tube that's necked down to about 2" as it enters the muffler.

 

Looks like people have many solutions to make a Camaro louder but there are much fewer to make it more silent

I could try to get a hold of a stock exhaust but that's sortof illogical On the other hand it's making more noise than I can accept. I've heard only ferraris and lambos make as much or more noise while cruising on the street.

Guess I'm stuck with it for the time being...

 

flexus:
A bullet muffler like this ( http://www.summitracing.com/parts/SUM-630820/ 3" I-O ,4" OD ,24" length ) should fit in the drive-shaft tunnel by cutting a piece out of an aftermarket 3" I-pipe. I wonder how much noise relief it provides? Is it worth doing?

 

I have considered this but it seems the exhaust is pretty close to the driveshaft... .5" should fit though I guess...

Anyone tried installing one of these, do they help with noise?

 

How about a CCI 3" insert in the 3" pipe before the axle kick. I sold my 2OTL (97ss). I used a 3 disc insert on a 3 1/2" Mufflex system. You can find them @ Summitracing.com. B.

 

This actually sounds like a great idea! This might work! I never heard of stuff like this before. I'll give them a call and see what they recommend for my application.

I'll try to install it in the Y-pipe maybe, or on the section after that.

If this works it's exactly what I needed - something that reduces noise, is cheap, will not require heavy modifications and won't kill my power.

Thanks!

 

I've got an SLP 2OTL muffler in my basement that I would sell if you need one.

 

you could always sell the exhaust to me and get something else

 

Maybe I would if I wasn't on another continent It's not so expensive to get stuff here but to ship stuff out to you... murder.

 

If all you need is a muffler with 1 in and 2 out there are others available, doesn't have to be from SLP.

 

well dang i cant win, but i know youre right ive been trying to get a sub box built for my truck by a wizard in canada but shipping is a killer
i have always liked the slp 2otl sound and just said if i ever ran across one i would like to have one. i may just say the heck with it and go true duals if i can find someone here that aint scared to do it and run them out the back i dont really want turndowns
