Q: Exhaust Updates
There was a thread a little while ago that referred to a great article about muffler testing. I printed the article, but I can’t recall the website.
I plan to install the headers I bought and need the rest of the exhaust from headers back. Is there place to call to order these parts already pre-bent for a 68? I don’t want to have to take the car in would rather order and then install in the garage. I can get a welder if needed. Anyway if anyone knows a place let me know. I want to go to the duel exhaust from my now single.
Also what do you all think of walker mufflers? I keep hearing flowmasters but was told by a reliable sorce and trusted car buff that walker was much better. Anyone have input?
A: You’re probably refering to the Jim Hand article on exhaust…
Titled “The Strong Silent Type”. Jim did extensive testing of different brands of mufflers, measuring backpressure, sound level, 1/4 mile performance. He also tested the use of different diameter tail pipes, “H” pipes versus “X” pipes, etc. He’s done more testing than most of us could ever afford.
Walker/Dynomax makes complete dual exhaust systems for headers as well as stock manifolds, as well as mufflers. Try calling Jegs or Summit and see if they can come up with a system for your car. So does Flowmaster, which is designed for headers. But Hugo manager to get one of their systems to work with his stock manifolded ragtop. The Walker is more likely to look stock than will the Flowmaster.
And of course, their is Gardner Exhaust Systems (http://www.gardnerexhaust.com/).
They make replicas of factory systems, which I think is offered in both mild and stainless steel. This is probably the way for Erich Wagner to go for that stock look, and still be able to install it himself. Expect to pay well for this product.
See the above link on some very good independent testing of various brands. While each mfgr. claims the best flow/power output, it’s interesting to see real world, on car testing like this.
On top of all this, an important factor is sound. Some folks like their cars loud (Bob raises his hand), others like them quiet. I like the sound of Flowmasters, while I know a few die hards who think that a set of glasspacks are the living end of great sound. Judging from the testing Jim did, if it’s quiet with superior performance that you are looking for, Walker/Dynomax is probably the way to go.
