Very simplistic view, wish it were that easy, trust us there is a reason why everyone is not doing it. Unfortunately, there is no legal use of an offroad pipe according to the EPA, and you don't have the right to convert your car for offroad use. If you purchased an emmission compliant vehicle...

A new Tune is recommended but not required.

We just did a Procharged 2020 on E85 made 863RWHP through these, have a few Coyote F150s making 1000HP with the F150 Version on GESI Cats. I can post the dyno sheets in a bit if interested.

Are we still arguing about Abu Dhabi? Max won, he will forever be the champion for 2021, in the record books it will never be denoted that Hamilton was "robbed". FIA fumbled the decision, although I may be amongst the few that think the correct decision was to have them race for it, they just...

The 48 State Legal cats at this point if more terminology than anything at the moment. It used to be California and NY, now the name has stayed the same, but they are not legal in any state that follows CARB. It used to only be those two, it has grown since then. The "48 State Legal" cat is...

Unfortunately not at the moment. Only Connections for a GT.

On Sale, and Standard Catted Ready to ship https://www.makperformance.com/2015-2021-Mustang-GT-MAK-Performance-Pipes_p_299.html

Yeah that is a turnoff, he is a great driver. By the numbers the best one ever, but he is like every other great, not squeaky clean, they are gritty, the push limits, and make questionable decisions. Hamilton in that regard is like the rest. You cannot come a crucify Max for doing the same.

Did I miss where LH became the Mother Teresa of F1?

Great observation I had not noticed that. I think the Andretti talks aren't over, just on Ice for a bit. I was really looking forward to that. I wonder how long Nikita will be in that seat, F1 is a Money Talks world, im not saying they aren't good, but look at Latifi and Stroll as well, I am...

Your too nice, I would have banned first and asked questions later. Were I serious, I would have booted myself. Although I really want to like Haas, they are technically an American team, I was a Magnusson and Grosejan fan and Gunther is literally pure gold. I love Mick, because his dad was...

Damn cant believe I didn't know this thread was here. Ill try to keep up now. Let's go Mazepin!!!

Check the actual vac to the valve and vac block, those are the most overlooked and pretty easy to have an issue with.

This is just wrong. If your that low on boost on a 4.75 you have a Vacuum Leak somewhere, i suspect by the Race Valve somewhere if its not making noise. 4.75 is 9psi on 18+ and 10psi on 15-17, unless we are talking about altitude. That changes the selections. That small difference isn't going...

Bump

It should not throw a code no. We have tested them here without any issue really in that regard. Yes we could absolutely use the 50230 in N/A cars and even mild boosted cars. The real detteret for us in that particular cat, is the price for the HP level. The UHO is not much more and we can...

Sorry guys was on vacation just seeing this now. Yes we have in house cars and trucks making around 1000hp without issue. They are designed not to melt. You do not get a Check Engine light with the GESI options. They are EPA Compliant and should pass emissions outside of CARB states. Gen 2...

Unfortunately those haven't existed for a good while. Different times we are in, we are working to stay compliant. If we can help you in any other way please do not hesitate to ask.

Not a stupid question at all. Yes you need to weld our provided flange onto the driver side header.

I completely understand what you are saying, however let me point out that our $1300 Set is with GESI Cats, any header set in that price range comes with an equivalent catalytic to our $699 Set, any GESI Catted, or "Green" Catted equivalent is Header set is north of $2000.00, pretty much keeping...
