Dual Exhaust with Air Ride

[Guest relik65]

My 65 had air ride on it when I purchased it last year. The exhaust stops short of the rear axle. I do want to keep the air ride. I'm looking for any tips or advice on running pipes to back of vehicle while clearing my rear air bags as much as possible. Any pictures of a similar set up would be lovely.

Here's a picture of what it should look like. You might be able to tell from this whether or not you'll have room for a stock system or whether you might have to do some custom bending. Some Camaros also used a cross flow muffler but it was shorter. Perhaps you could use the shorter crossflow muffler and custome bend the pipes that go over the rear axle. I believe the muffler in this picture is shorter than an original "water heater" sized muffler.

PS - This picture came from a different AACA Riviera Owner's thread. There is a lot of information out there that has already been discussed. Lots of times you'll get a quicker answer by searching the archives for applicable tthreads. If the info has been discussed previously, there's not as good a chance of getting a complete answer the second time around. Here's the link to the previous thread.

If you'll open this link and read the entire thread, there are pictures of Steelman's '63 that has been bagged and uses a Flowmaster Camaro muffler. Probably everything you want to know. Good luck and keep us informed.

Thanks a lot Ed. I searched the forums earlier before posting. Apparently I didn't dig deep enough. And your right. Steelman's photos are exactly what I have been looking for. I see now that I have some changes to make in order for a dual exhaust to fit. Have to change rear bags. Going to cost me, but I really want pipes coming out back.

Here's a article that may be some help to you.

Ricky,

If you're not worried about "totally stock," and I'm guessing you're not if your car is bagged, there may be another alternative.

You might consider and measure what it would take to put a couple of turbo type mufflers or "cherry bombs" in the cavities between the trunk floor and the fenders right behind the rear wheels. There's enough room to do it and you wouldn't be the first to do it.

My bags are all from Ride Tech, or Air Ride Technologies. I put the complete system on, with shocks and bags on the rear and shockwaves in the front.

Hi, I just became a member of the forum today and have been a ROA member for a year or so and I will be replacing my exhaust system shortly. If you check out the link I posted it gives an example of what Rivnut is refering to and provides pictures of the process. This will be the way in which I plan to route my exhaust because I can buy the mufflers at a lower price online and spread out the cost as I choose to, then have the muffler shop bend the pipes and install everything when I'm ready. Lowriders pretty much have lowering their cars down to a science and magnaflow has done the hardest part by doing all the fitting trail and error for us. The one thing that I am going to do different is replace the factory headers with a set of sanderson headers.

I did just that with a set of dynomax mufflers and it sounded great. Having the mufflers that far back made it a bit louder outside the car but quite nice inside. Also put some deep throatedness to it. I'd highly recommend doing it!

My bags are all from Ride Tech, or Air Ride Technologies. I put the complete system on, with shocks and bags on the rear and shockwaves in the front.

I am about to order up some shock waves my self. The kit that was put in my Riv is a bare minimum set up. Do those shock waves accept 3/8 air lines? Just curious on what all I might have to switch out.

3/8 lines are no problem. You can get the basic waves or the adjustable kind. Go to their site and enter the info for your car and it will show what is available. As mentioned in the link for the earlier post, do bags and rear wheels and tires before exhaust. Those will be the major obstacles for the exhaust tech. Link below.

That's the way I did mine. Ordered the muffler from Summit after I talked to the exhaust guy. Told him what I wanted and how I wanted it done. He said, bring me your muffler and the car. No problem.

PS, welcome aboard to you and Ricky.

Thanks for the welcome, I'm basically going through everything according to groups as outlined by the service manual. I just wanted to throw in the fact that spreading out the cost of items that I know needs to be replaced keeps my budget on track and provides a cushion for those unexpected expenses. Instead of dropping alot of money at once it's easier for me to buy one or two mufflers at once and also it motivates me to complete one project at a time so I know I'll have storage space before I begin something else.

I am ordering shock waves this week as well as rear bags. The wheels are already in place. (Chip Foose Customs 20x10) Should be pulling into exhaust shop sometime in July. Just have to decide cross flow muffler, or dual mufflers tucked up like what Ed and Gseago described. Probably cross flow mainly because it appears closest to stock. Thank you to all of you for helping me with this. My exhaust guy was slightly intimidated because of the bags. I think with this info and the changes I am making we will both be more at ease.

I have stock exhaust and air bags (shockwave/front , generic/rear) no clearance problems.
