They didn't include any holley on there though and I didn't see any in thread.
I wouldn't consider over spending on a $1200 on a crack prone, leak prone intake a flex.

Using the money you saved on the fast intake, and went with the tbss/gen 4.. then used that money elsewhere to help fund lets say a turbo or similar... would be a flex.

Holley then, I just think a different looking intake is a nice look


The only thing I despise about the TBSS intake is that corvette filter. I don't know why I just think it looks weird lol

I'm still confused

Your spending alot of money, to just go backwards in performance.. for a cool looking intake. Paint the filter black, and put a gen 4 cover on it

Idk spending that money and putting that intake on a na truck is pointless imo

Yeah that's why I'm not going to do it. It's called

I had asked about the LSXRT runners 6 months ago because I was looking at something totally unrelated to this truck and was curious. You'd only be losing performance on these intakes if you aren't revvin it up

Fortunately I know what vehicle I drive every day and in this truck it would be a tragedy. I still have it in my plans to go turbo on this truck though, just don't know when I am going to get around to that yet.

The OEM intakes are the bottleneck when making big N/A LS horsepower. You can have a stroker with the best flowing heads, compression and a donkey cam and leave a good bit of power on the table with a factory intake. The LSXRT's have had a lot of leak issues where the runners seal and I've read they're a ************ to tune. I'd go with the LSXR 102mm and change the water pump and accessories to Camaro before buying the LSXRT truck manifold.

I really wish someone would develop an aluminum bolt together FAST LSXRT style intake. This is more in regards to FI crowd though.

If you want to stay composite material I think there are two real options:

Mamo ported MSD Atomic is the ticket however you are SOL if L92/LS3 port as you only get Cathedral or LS7. Seems like he has a handle on them and you’ll certainly have some money wrapped up in that setup.

Carbon PTR intake with tall (9”) velocity stacks would perform well and certainly be different vs the Holley. It performed well in the big LS3 intake shootout too and honestly is not terribly priced.

There is an aluminum holley intake that is similar in it's modularity I believe
