These are clips of my 1965 Mustang. It has a 1968 200ci I6, Holley 2bbl carburetor, dual outlet header from Ford Six Performance, and dual exhaust with Borla ProXS mufflers. Here is a clip:

Current Exhaust

I have been thinking about installing Cherry Bomb glasspacks and side exit exhaust to see how it sounds on a modified I6. I started to remove the exhaust today (it is set up so the exhaust can be easily removed without cutting) and recorded the open header:

Open Split Manifold Header

A friend let me borrow some worn out Cherry Bomb glasspacks:

Cherry Bombs!

The open header sounds cool (of course). I love the sound of the Borla mufflers. I think they really give the I6 a mean sound. I've had guys mistake it for a V8. My intention is not to fool anyone, but it is a nice compliment.

The glasspacks sound ok, but I don't like them over the Borlas. However, these were pretty beat up. The packing was burned out a long time ago. I'm still considering trying a pair of new 8" glasspacks.

Pretty good for a six cylinder...let me know what you think!

Ya, the worn out Cherry Bombs will not sound like others and then if you mount them as I do, that changes things too. Remember too, the sound will be a lot different out of the garage. You are running in a bit of an echo chamber. Going to side exits and a different size tip will also make a difference. Isn't it fun, all these little things change the sound so much.....

all of them sound cool, better than my 6cyl. wish i lived in the US it`s hard to get parts for 6cyl mustangs in the UK and when you order them from the US it costs a fortune, more than the part. doh!

Great sound!! Btw, doesn't it always amaze everyone how similar the sound is to a V8? Back in the day, when I was in high school in the 1950's, a couple of my buddies had '50 Chevys with split manifols and although I loved the sound, they sounded NOTHING like the Chevy V8's. I will nerver understand that!!!

Usually a 6 needs to be as quiet as possable since enhancing the sound makes it sound like, well, a fart can. But those Borlas are really impressive. I guess I have to change my way of thinking! I wonder how it will sound outside of the garage though?

My 68 with the flowmasters and clifford header sounds great in and out of the garage. Some guy asked the other day if I wanted help getting my 289 running right. The engine was cold and I have never hooked up the choke on the weber. Apparently the guy heard my me when I got there lol. Anyway I told him I would love for my 289 to fun better. Asked him if he was gonna buy me the 2 cyl and the extra 89 cubes lol.

Just great- I was going to be completely content with one or two minor modifications to my I6... then I watch your video and will live an unfulfilled life until I install dual Borlas.

Thanks a bunch (seriously, this will definitely be a project for the near future)... great sound- great job.

Wow. I don't know the last time I actually had the Mustang running. It will probably be a long time before it runs. I was tempted to push it out of the garage and get it started, but there's no point. It needs a lot of work to make it roadworthy and I won't get to it for a long time.

Those Borlas did sound great, though.
