GT500 Exhaust on Mach 1?

[derklink]

Hi all,

What are your thoughts on (and perhaps experience with) the BORLA GT500 exhaust on our Mach 1s? Nice upgrade or waste of money?

Before you wonder...it fits with a connector they sell https://www.borla.com/products/ford-mustang-mach-1-connecting-pipe-60722

Or has anybody fitted the OEM GT500 exhaust on their Mach 1?

Thank you!

I am in the waste camp

I think @Zelek did with LTH as well.

I think that it would be waste of money and time.

I put a new take off GT500 CAT back on my M1 but I cut off the X and replaced with an H keeping the GT500 resonators. No long tubes. Sounds good, but so does the original M1 exhaust.

Interesting. How does it sound?

From a distance….volume up. My 17yr old driving on track for the first time. The blue M1 behind him was in front of him the previous lap!

I have the GT500 borla atak welded to the corsa double H pipe because the switchfire is 2.5” despite being advertised as a 3 inch exhaust also with LTH

Awesome that your kid is interested in this and seems like he feels right at home on the track. Sounds very good imo. Does your car still have exhaust modes or did you skip that since yours is a salvage built & track toy?

That must be LOUD

Everything is fully functional. I believe that was sport mode.

It’s loud on cold start but with quiet start and quiet mode from active exhaust, it’s very manageable

It's actually 2.75" which is the same as the GT500. This is why the 3" connectors from the headers don't work. I didn't try 2.5" ones because the 2.75" ones were already pretty snug.

As for the sound, it's the best exhaust I've heard and had on any Mustang.

That’s good to know! I thought it was 2.5. I didn’t try it because I already had the corsa double h pipe on the car so I sold the switchfire. It does sound awesome based on the videos I saw!
