Ok guys Im building a Stainless Exhaust setup for the Slingshots. I have a laser cut flange to bolt to the factory manifold and they will be full tig welded. We do a ton of auto and watercraft parts and just getting into these new toys.

My big question and this is where a forum like this can help is what muffler to run? I have been looking over the chevy boards for muffler info and clearly there is a ton of turbo info out there. For forced air setups I know. But just looking for what muffler makes the most owed on these motors NA.

Clearly with no Cat this will be a "for off road use only" or "for competition use only"

So what have you guys read on muffler combos for this motor?

Now were talking.

Just find something non ricey please!

Maybe just a cat delete and small straight through rezzie......

For a lightweight, low backpressure and pretty nice sound, the Aero Turbine muffler has worked pretty good on several of my projects. Available with a built in resonator or without. looks nice too, shaped like a short fat glass pack.

I have had good luck with Borla, but always on bigger than 4 cyl. This motor is just new to me

I haven't had a opportunity to hear how loud the SS is, but I wonder how a louder exhaust would help you get noticed in traffic, "Loud pipes save lives on bikes" an adage that was associated with riding motorcycles, and saved my ass a few times while out riding. A possible safety device?

When I heard the engine start up, I could hear a decent rumble out of the exhaust system. I don't want my SS to sound like a Honda Civic with coffee mug exhausts..

maybe with the Cat removed it might have a lower note?

The cat is awfully small, why not leave it?

Cat and stock muffler are all 1 unit

Could do a high flow cat and a high flow muffler. i guess we just built both and Dyno to find out where we stand.

 

[HotRod]

Yes. I won't be buying mods just because they are available. I want to see the improvement data based on valid testing.

Yep thats what we do. We have been in this game a long time. R&D is what its all about. and We may not be the first to have it out there. But we will be the best.

I've read that many times too, but that's not what it looks like below; see item 4 below.

I guess you could keep the cat and make a slip joint and a bunch of tubing to make a muffler sit. Ill try that too for the dyno. Going to be some fun R&D

In order to keep away from getting that Honda civic flavor exhaust, you will need to find a quality baffled muffler that still flows nicely.

If it were up to me, i would upgrade the header, ditch the cat and leave the stock muffler in place. That should give you a good tone without becoming too Fast and furious.

That was the setup i had on my cobalt and it worked perfectly.

 

[Noah Katz]

I thought I saw a pic recently of the exhaust manifold and it looked pretty darn good, almost like headers with real runners.

What would it sound like with just straight pipes? I don't think I've ever owned a four-cylinder!

I own a Harley and a Viper and when the SS rolled out of the delivery truck today I couldn't tell it was running. I know it will not stack up against my current toys and don't expect it to but I need something louder than this.

Here's what I have in mind if it's too quiet!

I was 6 when I did the same to my bike and fell in love with the rumble it made and I just turn 60 and haven't grow out of it I guess. Where would you suggest I strap them on my new Grey SS with it's Red SL upgrades. ( Best of both worlds " Faster and Good looking " now I just need the sound to go with it )
