Installed the fabspeed cat bypass pipes recently. Thought I'd share a sound clip!
Crazy loud with the exhaust flaps open, but fairly quiet with them closed. Best exhaust option in my opinion.

Click the link for the video (best way I knew how to link it)

 

That’s sounds awesome. If only the price of those parts wasn’t through the roof.

 

$1,300 for a 1 foot long piece of pipe

 

Is that one of 12" long pipe? Or two? No flanges?

People often forget development and testing time, spread over a relatively few buyers.

If it is such a high margin market, I presume you will be coming out with your own competing product. When will it be in production for sale at $50 plus shipping? Or will you throw in free shipping like Amazon?

 

Ya that kind of sucks, but it's cheaper and better sounding than a full exhaust system. Also comes with little fake mini cats so there isn't any CEL. Much easier and better than cat backs for this car, IMO.

 

Sure whatever you say.....but long tube has them for $500 cheaper and for a 12 inch pipe with flanges

 

I apologize to the OP....I misunderstood and thought those were the $3k sport cats. I really would want to buy those when the time comes just hard to see myself spending that much money.

 

Sound is identical to the FabSpeed Sport Cats with the NPP, which I have on my C8.

And the sound is even better live!!

 

Yeah but I think in NC they do a visual to see if the cats are there and I think those bypass pipes might not pass.

 

Does it throw any CELs using the cat bypass pipes? Are the fooler mini cats included?

 

They have fooler mini cats that come with it for an extra $250. No CEL for me. A few people have had them come on, but if it does, you can clear it with a cheap O2 code reader.

 

I've heard the sound from their sport cats and cat by-pass pipes is nearly identical, can anyone confirm this?

 

Sound good... I have always been a fan of off-road pipes/catless setup. But as I am maturing I find the smell to not be as appealing. Have you driven with the top off?

 

Yes. You smell it a little bit at stop lights when you're sitting there, but it's not too bad.

 

Our Sport Cats incorporate premium 200 cell HJS catalysts that flow about 85% of straight pipe - so there's really only a very slight difference in sound. Sport Cats come with a No Check Engine Light Guarantee - no tune required - no raw fuel smell.

Cat bypass is considerably more affordable, the slightest bit more raw and raspy, and we do encounter the occasional complaint of exhaust fumes depending on driving conditions, and the occasional CEL - which can be cleared with a cheapy OBDII scanner as noted.

Regarding the pricing complaints, it's not too different than the C8 itself. Many are outraged about this or that dealer mark-up of $10k or even $25k, others see value in the car at that price and stroke the check. For more budget oriented clients, there are often price considerations and promotions to make things more affordable. Example: Black Friday was 15% off and Free Shipping. Something is likely in the pipeline for Christmas as well. And I'm always willing to make an incentivized offer for members here.

It's almost never an apples-to-apples comparison. As an example, I haven't seen any heat insulation on Long Tube products - a BIG factor we considered during engineering, research, and development.

 

I purchased those mini cats. They did not work for me. Kept getting po420 codes.
And it smells really bad like emissions. After that I put a set of high flow converters. Now no po420. And no emission smell.

 

Whenever cats are removed, a proper tune is the only guaranteed fix - and this solution is not yet available.

O2 Spacers help, but they're not a guarantee to keeping the CEL out. They tend to do well with smaller displacement, naturally aspirated engines. At 6.2L, the Corvette is probably just about at the limit of their effectiveness - especially under high load and rpm. The Sport Cats achieve 85% of the results with none of the hassle and aggravation.
