Header question

Jcbr1 · 06-03-2019, 07:17 PM

Has anyone used texas speed headers. They seem like a bargain price wise vs kooks, or American racing.

I have them on my 18, quality and fitment was good especially for the price. I do not have any complaints about them so far.

I know a few SS guys with them and they have no complaints. I myself planned on getting a set but I'm still not sure what direction I'm going with this car. If I do decide to keep and modify it then I will go with TSP.

I was going to use them as I’ve heard good things and the price could not be beat, but after I factor in $650 for the headers and off road pipes plus $300 for ceramic coating I’d be at $950. Still a good deal but there are sales now on Kooks headers and ceramic coating so I went that route for $1200. I figured it was $250 more but there would be a qorry free fit.

I heard the TSP 1 7/8” fit great but the 2” may need some clearance at the steering joint.

The 2" is where some start seeing issues. I had those issues in my SS - and had to bend/hammer them a bit.

I was just looking at those yesterday. I am unsure about headers and the "street legal" issue. Seems like most are race/offroad only so I really don't know which ones to buy. I would like to get a full system and keep the NPP and get rid of the flattened pipes in the back

Many aftermarket headers provide that disclaimer - it is just a legal shield. However, some states have laws/regulations on noise levels, and on deleting the cats.

I was kind of wondering that is that GM says that ARH is the GM Official Header but yet they all say off road. I see the Green Cats on Kooks so to me that would make it legal for emissions. I have not modified any exhausts for a long time.

Here in south TX “no cats no problem”.

This is what I looked up awhile back......So of course I have to be living where I can't have the most fun.

In places like cali you can fail smog regardless of green cats.

This is true. California hates fun!

If by Grapevine you mean So. Cal. unless you have CARB-compliant exemption numbers on your cats and headers, you will not pass a visual. Kook's green cats' are not 50-state compliant last I heard. Even if you find aftermarket CARB-legal cats', you still won't find CARB-legal long tubes. The stock manifolds flow reasonably well, but they still aren't headers...

I finally found the sound that I like and I think beats the GT350R sound. It is at the end with ZL1 and red wheels.

Sounds like he put a cam in it...
