ALL COMPONENTS SOLD AS OF THIS MORNING.
As many of you are coming to realize, the Dodge engineers are pretty good, ot at least I think so - or else I wouldn't own two Intrepids and a Magnum. When Dodge set out to build a hot-rod LX platform with a 6.1 liter Hemi engine they upgraded most of the car's components to match - including the exhaust system. You might want to look at http://www.lxforums.com/board/showthread.php?t=35715 for information on the effectiveness of stock SRT8 components on either the 6.1 or 5.7 liter engines.

I have for sale a pair of factory stock SRT8 headers and catalytic converters. I bought an entire SRT8 exhaust but was pleased to find that I only needed to use the resonators to quiet the current exhaust system down. I was working with a car I had bought on which the prior owner had installed a Borla system with long tube headers, straight through mufflers and straight pipes - no resonators - in back of the mufflers. Too loud for me.

Price is $200 for the headers, which look to be mint, $150 for the catalytic converters, also mint, or $300 for all. If you want the stock suitcase muffler and mid-pipe, add $50. These prices include shipping east of the Mississippi. If you are west of the Mississippi, please add for shipping $10 for just the headers or $20 for the headers plus converters (and muffler).

These are pretty bulky and heavy items, so the prices including shipping seem reasonable to me. If you want to pick the parts up in Framingham, Massachusetts the prices would be $150 for the two headers, $100 for the two converters, and $25 for the muffler and mid-pipe.

If you want a very low restriction and aggressive sounding - but not crazy loud - system with excellent flow characteristics, you could buy all of these SRT8 components (headers, cats, mid-pipe and muffler) and use 2.5": straight pipes in back of the muffler.

You can reach me at (508) 872-4249 or rpgoodkin@rcn.com.

Thanks,

Richard

How do these cats compare to the (HHP offered) high flows that are out there?

Hi,

I can't answer your question. The pipes are 2.5" and the converters are not as small as the converters that came with my Borla system (the exhaust shop called these tiny converters 'pre-cats'). All I know about this stuff is what I read on this LX forum, especially the excellent thread at http://www.lxforums.com/board/showthread.php?t=35715. Sorry to not be of more help. I guess I'd trust the Dodge engineers to come up with the best balance of performance, sound control, durability, etc. The closer to stock you can stay the less chance of CEL or engine malfunction indicators. The 6.1 Hemi is a powerhouse - it must breathe pretty freely through the SRT8 stock system. Unless you have a radically hopped up engine, I can't imagine the need for anything more than this.

I am interested in the headers, do you have a picture of them? I am wondering just how much different they are from the 5.7 Daytona manifold. I'd appreciate it if you could maybe PM me a picture or just post it here.
