So if a reputable ehaust fabricator started producing header back systems that were mandrel bent, 2.5", twin loop/twin pass style, with 2.5" resonator (probably magnaflow), 2.5" cat (probably carsound w/ 02 bung), and 2.5" muffler (again probably magnaflow), similar but not identical to a Hytech unit, and reasonably priced, would anyone be interested?

High flow, low sound.

Something like $400-450 for a mild steel version and like around $550-600 for all stainless. Again this is all hypothetical as of now but your opinion matters, so speak up. Thanks, JFoster

 

Hey jfoster! Good to see you keep at it!

Designwise - do you have any for of layout of the system?

 

Some pics would be good. I'd be interested in a 2.5 axle back.

 

Yeah, I know what parts I will need to make it. Haven't ordered them yet so no pics. I just think there should be a bargain model for people who can't spend 8 or 9hundred or more on exhaust. So maybe its mild steel instead of stainless, or not tig or mig welded or what ever. As long as it doesn't leak I don't care. High flow with low noise is what I want. Why does it have to be so expensive? What good does amazing quality do a person when they'll never be able to afford it anyway? It would be nice to just order it and bolt it on rather than scrape all the parts together and then explain to the muffler shop how to put it together, and why. And then have them look at me like I am retarded.

 

twin loop != high flow

 

I might be interested...

Can you explain the above statement a little better sGt?

 

High flow = straight through

A "twin loop" system is going to add unnecessary restriction in flow. If you have a decent muffler (not ebay junk) and resonator (again, not ebay junk) then it will be quiet.

 

actually i have a legitimate question about aftermarket exhausts and those that 'design' them... for the components to be bolt-on, you'd have to follow the path that the stock exhaust takes (ie. every bend etc.).. with this in mind, what kind of 'design' is needed if you're restricted to following this path? personally i would think that as long as you keep the same diameter piping without any discontinuities, an exhaust is an exhaust is an exhaust....
of course if you could change the path of the factory exhaust, that would be where the real designing takes place..

 

twin loop = high flow and low noise. And straight through = high flow but loud.

By taking two straight through passes through the muffler the twin pass design offers twice the sound absorbtion, yet still high flow since the loop is mandrel bent for a smooth flow. Twin loop/twin pass is the best design out there, there is a reason Hytech systems utilize this design, because they know what works best.

From the header straight back would be the highest possible flow design, thats why some racers and turbo cars use that design. But it would have to sit well below the car instead of being tucked up like the stock system. For a street driver it would drag alot, and eventually tear up your exhaust. Besides, as long as the system uses mandrel bends the flow is minimally restricted in the corners, if at all.

This system would be far superior (in flow and sound restriction) to the stock system or even any of the less than 2.5" after market sysytems (which is most systems). 2.5" is the best performing piping diameter, again Hytech uses it and they aren't just guessing.

If this was made as a header back system, people with 2.5" collector headers (all the great headers, JDM ITR 4-1, JUN, Spoon, Comptech Race, Hytech, SMSP, etc.) would then have a full 2.5" exhaust with no restrictions, or bottle necks, and it would be relatively quiet, especially compared to a straight through muffler.

Saying all exhaust systems are created equal is far from correct. Yes the main advantage is the increase in diameter but when compared to a stock or shop made system that uses crush style bends the mandrel bent system will flow perfectly while the crush bent system will encounter a restricting bottle neck, or decrease in diameter at every bend. A 2.5" , mandrel bent, twin loop style system would be the highest flowing exhaust one could have, and it would be quieter than a straight through muffler. Hytech uses this design, thats why they have probably the best performing system available. My only qualm is that it is just not logical for me to spend that much $$$$ on a system. Their system are top quality, and probably worth every penny, but I personally would like a similar system (in design, high flow+ low noise) for less money.

Would anyone else be interested in this type of system if it were available for a more resonable price?
