Long Tube Headers question

[Joe5oh]

Hey guys I have a 2020 mustang GT A10 PP. I’m pretty green in the area and keep getting different answers. I’m looking at having LTHs installed. Is this a possibility without changing the stock exhaust/mid pipe? Or would I need to change the mid pipe, catback etc? Sorry if it’s a stupid question, thanks in advance for help guys!

I believe stainless power headers offer a factory hook up

So do Texas speed. I have catted Texas Speed and it hooks directly up to the factory resonator. I do have a Borla system but it is converted to the factory hook up...

What does that step down to?

They’re like 3 inch to 2 1/4 but it’s still more than enough for a stock engine

Thanks a lot for the input What size did you go with to bolt on to the resonators?

You’d lose your factory cats but just get the high flow cats and you’ll be fine. I know LTH and Stainless Power/Works have their factory connect options that’ll allow you to run your factory catback on the car. That’s what I run with the Mach 1 axle backs. If you have the stock non active exhaust, it’s gonna sound like you have a factory exhaust with an H pipe. But if you have active exhaust it’ll sound pretty good. It’s up to you, but headers are a nice option.

Hmmm… it seems to me that with the expense and effort of installing LTH’s that there is a better solution to making the connection to the stock or aftermarket exhaust system? If all that is wanted is the sound of LTH’s then I guess that this would be OK. But, if performance gain (and there is more needed than just bolting on the headers) is the objective then the step down and step up connection is counter productive. Were this my set up I would have 3” pieces made and welded into place where the goofy pieces are. Yes, it would cost some to have a good job of fabricating the pieces and welding them in, mostly due to having to drop the pipes to weld them, but I am sure that the best gains and appearance would be had this way.

I have a cat back 3” on my car and LTH’s are always at the back of my mind. And, will most likely be installed when I rebuild the motor in the future.

This is intended as constructive criticism only and there is no intent to degrade.

It is factory size. It is indeed a step down and step back up. I believe its 2.5 inch.

Yes, stainless works and Texas speed has a "Performance connect" which does not neck down at all. I went factory connect to make it easier. Running NA there is virtually no performance impact. If/when I go boost, I wlll definitely fix the bottle neck especially since the Borla X pipe has a reducer on it anyway. Just remove the reducer and put a piece of straight 3 inch pipe in between, no problem for a muffler shop to cut and weld in place....

I have Long Tubes, no cats, stock resonator and stock catback. My car still made 800hp. You should get high flow cats with your Long Tubes then keep the rest. After the cats it's just noise, not much to be gained anyway.

Would like to see back to back dyno results of both an NA car and blown car using an aftermarket x pipe vs that step down
