Flowmaster Exhaust Kit 2.5" Stainless Steel With 3" Tips Coupe/Fastback V8 1967-1970 is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Superb Fit, Great Quality, Perfect DIY Exhaust The Good: I am impressed with the way this exhaust fits to the car. The bends are spot on and it truly a bolt in installation all the way up to the where it meets the headers. They provide some curved pieces you will need to adjust and then cut to mate to your headers. The quality of this kit is excellent, and looks like a professional installation. The kit comes with heavy duty clamps so that the only welding required is the final pieces that mate to your headers. I opted to weld the all seams except the joint between the mufflers and rear section that goes of the wheels for easy removal if necessary. Bad: The bolts that clamp the tips to the exhaust pipe are a joke. They are undersized and try to work down into the holes, and when you get them snug, but not tight enough to clamp, they skip threads. Fix this by welding the tips on or replaced them with larger bolts. I opted for the latter so I could remove the tips if I wanted to change them out at some point. Sound: The sound is amazing. Truly sounds like a mean muscle car with my mild 302.

Product Questions

I have a 1969 mustang hardtop with 302 and 4 speed standard trannny.   Can you recommend a set of long tube headers to go with this flowmaster exhaust kit #817281 and that would be compatible with ford GT-40 cylinder heads ?    Any modifications needed?

Asked by: Dalestokes
We only carry shorty style headers that would work for your application, http://www.cjponyparts.com/hedman-shorty-headers-elite-square-port-289-302-1965-1973/p/EXHD31/, these are also available in a painted and HTC coated version's. Custom down pipes would have to be made to work with this exhaust.

Where do the tail pipe hangers bolt to on the rear frame rails, the bolt holes are horizontal not vertical like the stock hanger.

Asked by: Tausy
There are three holes in the rear frame rail, and the hangars bolt in the front most hole.  There may have been an existing hangar or tie down plate bolted there that may need to be removed.

I have a 1967 Mustang coupe 289 auto.....Is there any advantage or difference between short or long headers?   Do you recommend a good all around combo for a 289

Asked by: Robin98011
Full length headers create more torque, whereas short headers create higher horsepower. It depends on what you're looking for.

Flowmaster Exhaust Kit 2.5" Stainless Steel With 3" Tips Coupe/Fastback V8 1967-1970 Video Transcript
By Bill Tumas: Bill: We have a special guest in our studio today. Alex, the regional sales manager from Flowmaster, is here to tell us about the company. Alex thanks for coming.

Alex: Thank you for having me Bill. How are you doing today?

Bill: I'm doing good. We all know the two chamber Flowmaster. If you had a Fox Body back in the day you had some Flowmasters on it. But what else can you tell us about your company?

Alex: Well, Flowmaster is an aftermarket performance exhaust manufacturer, Bill, that started off on the racetracks. Ray Flugger, the founder of the company, designed mufflers for racers that were being hammered for excessive noise limits. Flowmaster presents that opportunity where you're able to reduce those dB levels without having to hurt or kill performance. Flowmaster is also one of the most significant speed parts of all time where we are actually an innovative product different from the standard that's out there.

Bill: The two chamber Flowmaster that was the original product he was selling out of a suitcase.

Alex: The 40 Series, except with some slight modifications on the case itself. Back then it was a square case and now it's more of a round oval.

Bill: The other mufflers you have here, what can you tell me about them?

Alex: Here we have a 50 Series Delta Flow to the far right, which is a three chamber design, a little more subdued, a little mellower for those that are looking for less interior resonance. In the middle here we've got a Super 40, which is a two chamber design, a little thicker, a little wider, which is set up to handle higher output applications. To the far left we've got a Super 44, which is the latest and greatest two chamber design that Flowmaster has released in recent years.

Bill: Is that still based off of the original design?

Alex: That is correct.

Bill: I know Flowmaster has a lot of kits available for the 2005 and newer Mustangs. What can you tell me about these two kits you brought with you today?

Alex: Well, Bill here we've got a Force II exhaust system from Flowmaster. It's a direct bolt on axle back 409 stainless steel with a limited lifetime warranty, fully constructed here in the U.S. It's got the rolled edge stainless steel tip with the nice four inch diameter. All of the hardware, everything you need, is included within the kit so you don't have to buy any additional accessories.

This would probably take you an hour and a half to install out of your own garage on a weekend. Very subdued, very mellow kind of tone, something designed for someone who's looking for more of a performance aspect with a little bit of rumble, nothing too wild, nothing too crazy.

Over here on the right we've got the Outlaw System. The Outlaw is very noticeable, very aggressive. It's the 'hear me from a mile away' type of sound, something I would only recommend to those who are fully aware of what they're getting. It utilizes an Outlaw race muffler, basically a muffler that was designed for race applications that are required to run mufflers without a specific dB limit. Again, I only recommend it to those that are looking for the aggressive tone from Flowmaster. It is fully built out of stainless steel, lifetime warranty as well.

Bill: The Outlaw is available for '05 and up for both the 5.0 liter and the 4.6 liter cars?

Alex: That is correct.

Bill: We know Flowmaster that has systems that fit all year Mustangs, but I heard you guys are getting in other parts of the exhaust as well?

Alex: That's right, Bill. We actually just released a full line of stainless steel headers, ceramic coated, very high end piece. They look great. It'll compliment the rest of your exhaust components. We also just released a full line of catalytic converters, both 49 state and carb certified.

Bill: If you're looking for that classic Flowmaster sound, it doesn't matter what year your car is, Flowmaster has a system that will fit your Mustang.
