Exhaust system

I have a 65 El Camino and I would like to install a new exhaust system. I have posted a similar thread on the El Camino forum, but most of the recommendations are to find a local shop and have a system built, and yet to have anyone give a good or bad recommendation regarding what I have found as commercially available systems.

I bought my old car to drive and enjoy but I also prefer to do all the work myself that I can. I've done two body-off-the-frame restoration of a 1960 and 1966 Corvette. I bought exhaust systems from a major Corvette parts supplier and both fit very good.

My El Camino is a small block and I want a dual exhaust system.

I want something that is very close to OEM design but with mufflers with some more aggressive sound. I have found what I think are three candidate available systems. My car is a driver and I'm not trying to get to a concours level with the car.

Gardner - Seems to be the best and most accurate system, but very expensive. Probably $1,000 plus

Waldron and Classic Exhaust - these two have mixed reviews, but more positive than negative and are half the cost of a Gardner system.

Does anyone have experience with Waldron or Classic?

Thanks,
Don

Hi all - not sure if my question is breaking forum 'rules' but I am making this same decision now. 69 L78 - want/need a whole system. I contacted Gardner and got a quote of ~$1400? Other vendors I might check?

Re: Exhaust system

If you want a concourse correct exhaust system for your L78, Gardner is the system for you. But $1400 is a tough pill to swallow if 1st place on the show circuit isn't your top priority. The systems mentioned in my previous post are all 2.5" high performance systems that out-flow OEM systems and allow you to chose the sound you want. OEM style tips are also offered. It all just depends on what you want, OEM perfect or something with a little more sound and performance. BTW, Dynomax Super Turbo mufflers offers the best of both worlds in my opinion, great flow without the annoying drone or excessive noise.

Re: Exhaust system

I'm looking at the Classic Muscle Car Exhaust site. All of the systems pictured are rear exit and I want to have the behind the rear tire exit. I went to the Pypes web site and it doesn't show any behind the wheel tail pipes either.


Also, all the ones picture look to need a two piece front pipe assembly. A separate header (manifold down pipe) which I assume needs to be welded to the second pipe. This really doesn't both me but I really want the look of the rear wheel exit.

I like the looks of the Pypes system if they have the rear wheel exit. I'm going to give them a next week.

Thanks,

Don

All of those systems are designed for manifolds or headers, therefore requiring the use of separate down pipes for manifold use. No big deal. Flowmaster #17120 exits the way you want it. The Pypes system can be cut and an extension welded to exit in the stock location.

Re: Exhaust system

I went with the Inlinetube system for my 68 L79. Their mufflers produce more power then stock but look stock. I also opted for the larger 2 1/4 inch tailpipes since the stock system is very restrictive. These use all stock hangers, pipes (without crinkle bends) and other components for their systems. I paid around 700 bucks delivered. Give them a call and see if they make one for a 65 Ellie. Their online parts listing is less then complete.

Sorry about the rotate, old pics

Re: Exhaust system

I have a 64 EC that has a stock 283. I went with Waldrons with stock mufflers.
The tail pipes exit out behind the rear wheel as the original tailpipe did.
I am very satisfied with their system. The only problem is they have a 6 week

lead time.
