Am thinking of putting a dual exhaust system on my 69 convertible. I have a 350 CI motor with 2 barrel and automatic. Not looking for a noisy system, just nice mellow sound maybe. Any recommendation for mufflers? Thanks....Gary

 

Turbo mufflers

 

I just put these on from Summit http://www.summitracing.com/parts/SUM-680101/
They went on pretty easy, and not too much $$$

I have the Flowmaster system with the Series 30 mufflers (2.5") on my '69 and it sounds great. It's a little loud under pressure and has a nice mellow tone when cruising. They have different style mufflers for louder or more mellow sounds. Check out their website or Summit Racing for details.

 

The best way to describe a V6 exhaust is as a bottleneck: gases leave your engine through the two manifolds but get slowed down after the catalytic converters, where they are forced through a single pipe to pass through the muffler and out the tailpipe. It's not hard to see why the V6 exhaust set-up restricts air flow and limits power. Converting to a dual exhaust will open up the air flow, increase your horsepower, improve your gas mileage, and give you a deeper, throatier sound.
It has been said that there are two ways to convert your V6 exhaust: the right way and the wrong way. While we agree that there is the easy way and the hard way, we think it is better to give you all the information and let you decide what is right for your V6. That being said, there are a couple of ways you can convert your V6 to a dual exhaust.

1. Use a Dual Exhaust Adapter KitUsing a dual exhaust adapter kit requires cutting your Y-Pipe right after the catalytic converters and welding the adapter into place. The adapter acts as a splitter, allowing you to bolt any GT catback for your year Mustang right up to it, giving you the look of a true dual exhaust.
   The downside to this is that using this kit does not actually give you a true dual exhaust. It gives you the look and sound of a GT exhaust, but you will only see minor performance gains.
   
   
   1. Use a V6 H- or X-PipeThe second option is to use a V6-specific mid-pipe. Designed to eliminate the single-pipe design of the factory Y-Pipe, these bolt right up to the factory manifolds and give you a true dual exhaust. With this option, you can use any GT catback for your year Mustang.
      Because this conversion gives you a true dual exhaust, you will have noticeable performance gains. You car will be able to support more horsepower, though how much of a horsepower gain you will see depends on whether you keep your cats or go for an off-road set-up.
      Of the two options, this is the easiest. There is no precision cutting or welding, and it can be done by anyone with basic tools and knowledge.
      Note: For the record, AmericanMuscle.com recommends professional installation of all exhaust products.

Other Recommendations
If you have a stock V6, there are a few things we recommend to keep you from losing low-end torque and having a sluggish car.

1. Get a mid-pipe with catalytic converters. True, you won't see as much of a horsepower gain but, using a mid-pipe with cats creates enough backpressure to keep your low-end torque drivable.
2. Use a Chambered Muffler (such as Magnaflow, Steeda, Pypes), instead of a straight-through muffler.

Note: If you really want to use an off-road mid-pipe on a stock car, switch to steeper gears (4.10s or higher). This will get you into your power band faster, and the low-end torque difference will be less noticeable.
If your V6 has forced induction or nitrous, it is okay to use a straight-through muffler and an off-road mid-pipe.

 

OK Sarrienbarry, did you read the post right or what? How did you get v6 outta that?

 

i have a stock dual exaust but with a z/28 muffler it has a nice low rumble but it makes a statement when you put the pedal down (it also doesnt stick wide open like toyotas)

 

You do understand that the over the counter Exhaust will not fit your rag top? You have two option find a shop that will make a custom exhaust or replace the center brace to give yourself more tunnel clearance.

 

You can also order an OEM repro exhaust system from Ricks and then replace the muffler with a Flowmaster or what ever. As Gorn say's though, the standard performance aftermarket exhaust systems wont fit a convertable without work to the support plate. Also, No "X" or "H" pipes will work.

 

The guy is a troll. Don't pay much attention to his posts. So far they've had little to do with the topic.
