408LSX

Seems to pull harder up top and throttle response seems better. I still need to get it retuned also.

They are different, I just did the swap yesterday. The L83 has an 80mm tb and the L86 uses 87mm tb. The opening on intake is clearly bigger.

We get that you are a ARH and Kooks fan.if Have you ever had a set of TSP headers? They are very well made for the money. Not everybody wants to spend the outrageous amount for a set of Kooks or ARH when you can buy the TSP and make just as much power. And they will last as long or longer than the vehicle. I have a set installed on every vehicle I own and have never had a problem with any of them. They still look as good as the day I installed them.

Nice numbers, I bet it runs strong!

Texas Speed headers are stainless and the quality is awesome for the price. And they will make the same power as Kooks, or any of the other big name brands. Pacesetters are good headers for the price but will eventually rust, even with ceramic coating.

They are super nice headers for the money. They look and fit awesome! I have a set on my 02 Camaro SS, 2015 Camaro 1LE, and a set on my old 07 GMC. They all fit perfect and the quality is top notch for the money you pay. I will be installing a set on my 14 soon.
