2020 C8 Corvette exhaust comparison. Soul performance cats vs Fabspeed cat back exhaust.

2020 C8 Corvette exhaust options. Black c8 has Fabspeed cat back exhaust, and silver C8 has just the Soul Performance cats. Both options sound good but are quite different. Let me know what you think!

[@Martin_Steven]

Fabspeed definitely gives it that more exotic sound ...all sound sick but for me the fab speed is the one !!!

[@Paff805]

This definitely helped me make the choice for my C8. HIGH FLOW CATS !

[@S.Alton.C]

💯 Agree! High Flow for the win!

Stock exhaust is good way better than a lot of other cars stock. Fabspeed sounds super clean almost too clean. The high flow cats are right on the edge of raspy. Picking an exhaust for this car has been a challenge to say the least. Great video and comparisons it will help further my decision for sure.

[@Killer_Dwarf89]

Great comparison. I know this is all about personal taste but I liked the sound of the performance cats over the cat back/xpipe. But they all sounded great so we're really splitting hairs here. My HTC was built 1 Dec so I'm just waiting on delivery but will go down one of these paths myself in a few months. Excellent comparison!

Thanks for this informative video. It’s crazy how much louder the stock exhaust is from that cat-back system. But the cat-back does sound more refined for sure. The high flow cats are definitely louder and I like the way they accentuate everything from the stock exhaust.

[@jrock702]

[@velocity313]

Thank you so much. I've been trying to decide between the two. Whole time I'm watching I'm thinking they better do a drive-by and you did.

[@jrock702]

Your welcome... First impression I think I like the soul performance cats better than the fabspeed cat back. I did drive both but had limited time behind the wheel. They both had unique characteristics with the type of sound and volume.

[@Ownuout]

Thanks for the video. The factory exhaust actually sounds way better than I thought they would given the chatter. It would be nice to have the factory performance exhaust option in the mix too. I do like the fab speed the best (better blend and smoother than S.P Cats IMO) but with dyno (if necessary) not sure of cost/benefit over the factory performance exhaust option.

[@jrock702]

Your welcome! it's a tough pill to swallow as far as the cost/benefit considering that I'm pretty happy with the way the car sounds stock.

[@terrancegriffin1046]

Love the cat back deep sound but don't want to loose the original sqare tips. I think the next best thing is the soul performance but all 3 sound great to me

[@underfedcoyote5.022]

They all sound good but I’m leaning towards the black car for best sounding my opinion. Without driving the cars the black one seems to have the best all around sound that I like.

[@paulcodi2747]

It really is a personal preference thing. I own the silver car, but I still like the black car. If you want a tight lower tone, the cat back sounds great.

[@jrock702]

They both have positive attributes but are quite different. Would love to hear the combination of cats and cat back exhaust... That might actually be the winner...

[@underfedcoyote5.022]

@@paulcodi2747 ya I like them all but on video the black one seemed a little more mellow. But kept the good sounds the stock has. Maybe in person I would change my mind too. Sometimes cameras don’t pic up and play back threw phones great. But I love all 3 cars gotta get a c8 someday.

[@paulcodi2747]

@@underfedcoyote5.022 actually, the black car with the fabspeed cat back system sounds way different than the stock. It is way deeper and louder and more smooth sounding. No cracks pops or left and right exhaust cycling. It is more mellow, but does drone a drop in the cabin in 3rd gear at around 2500 at load. The car backs sound more like stock but 50% louder and more exaggerated raspy growl.

[@Motleymick]

While the systems all sound great, the component differences are both unique in changing the sound in their own way. A High-Flow catalytic converter will change the sound differently than a Cat-Back exhaust, which was the point of this video. But it's almost like comparing apples to oranges and asking "which tastes better?"

[@jwrice743]

True. People do like hearing different sound options though. I will check your link out.

[@FabspeedJohn]

@@jrock702 I mean, yea. People do like comparisons if you are comparing the same product from two different manufacturers. Comparing two completely different things doesn't provide any helpful info. Should check out some videos of both manufacturers' Sport CATs if you want to find out which is the best option.

[@totallyradjeff]

Fantastic video demonstrating exhaust systems. I picked up my 2021 C8 January the 10th and haven't driven it much due to Utah's Rocky Mountain snow. Now it is beginning to look like Summer is finally here and I know I want to upgrade my stock exhaust but not sure which one to go with. There are so many options out there. I like the one guy's comment about it would be interesting to see and hear a combination of the Cat-Back and the Soul Performance. I think the Soul Performance is just a bit too much raw sound and the Cat-Back is a bit too mellow. I would love to see and hear a combination of both for my car. I must admit, the sound (even if it is a bit raw) of the Soul Performance is more of what I would go with. I do like the idea of keeping the on and off option loud and softer as in the stock exhaust system...for my neighbor's sake. Any suggestions other than that which you have demonstrated? Also, can you provide cost options on the two systems used in your video? Thanks for the perfect demonstration vid...just at the right time also. Jeff in Utah

[@jrock702]

Thanks. Soul performance high flow cats $2,895 plus installation charges. Fabspeed non valved system with carbon tips like the one on the black car $3,395 plus install charges. If you want the valved system with carbon tips it's $3,995 plus install charges.

Hey great video sir!!! The soul sound amazing that’s now that’s the sounds I’m looking for!! My only problem is that I hope it doesn’t void factory warranty when you switch out the cats?? Please tell me no 😂😂

Swapping out the cats shouldn't void the warranty. I would check with your local dealer just to be sure though. However, some states require smog tests and are stricter than others. I would look into that as well.

The soul at idle and rev has more of a exhaust leak kind of rasp. The cat back has a very clean sound. I go for the cat. But its hard to tell how loud the cat is over stock.

[@jrock702]

at idle and wide open throttle soul is a decent amount louder. sounds really good and aggressive without be ridiculous. cruising at low rpm almost as quiet as stock. check out chevydude on youtube for decibel levels for soul.

[@derekb5749]

Hard to really get sound through $20 speakers, but I think the stock exhaust is actually an X Pipe just covered up by the muffler case.

The Soul Performance Cats are supposed to add a little horsepower and throttle response. I only drove the car for a few min... I can't say for sure that there was an increase of performance that can be felt. Sounded great though. The Fabspeed cat back sounded pretty good as well. Once again only drove that car a few min as well. No real performance gains I could tell. These mods are more about the sound in my opinion.

I would say on your scale for a stock c8 being a 5... Then I would say the fabspeed is 6-7 range. Not too loud at all. However, there is a little annoying drone at 2k-3krpm... It is really just something people have to experience first hand when it comes to exhaust volume and sound.

[@okaythen001]

HP gain with those? for the non-NPP from factory, is it quiet all the time or loud all the time?

[@jrock702]

Aftermarket exhaust/ cats will give you a more aggresive sound. Maybe 10-20 more Hp. We didn't dyno any of the cars before or after to verify though. even if so, it is not noticeable. Most people just do these mods for a sound difference. Exhaust mods are also sometimes used as supporting mods as well if you were to boost the car or add a heads and cam package. Then the car would need to be tuned though (not available currently) and then your warranty would be voided as well. I will most likely keep my car stock for now. Might possible do an exhaust in the future but honestly kinda feel it's not worth the money to do so. Time will tell.... Also non NPP from the factory is quite all the time with stock exhaust. Ordering NPP when getting a C8 is a must in my opinion unless you are going to change to aftermarcket exhaust for sure and like it loud all the time.
