Xtra Report post Posted September 15, 2022 (edited) Did a little research last night on cross pipes while thinking about a resonator delete . I ran across three mufflers that have internal cross pipes and one with an H pipe. Starting in order of last choice to first choice . This is just my opinion and not based on anything else. I also do not have all the dimensions on any of them. So not sure if they will fit in the space that the resonator was in. In third place is the Dynomax. Dynomax come in third place because it has one pipe that has straight flow through and the second pipe looks like it is cut in half and is just butted up to the other pipe. All the exhaust gas from that pipe has to pass through all those small holes as the straight pipe appears to be not cut on it's sides. Thus making it not a true X pipe. If the sides are cutout making it a true X pipe then I would reconsider. In second pace is the Magnaflow TRU-X This looks like a good choice for a quieter muffler but, it looks like it has two pipes in and out that connect to a mesh cone shaped screen and again is not a true cross pipe. In first place and my choice is the Pypes X=Box this design combines a true X pipe with a muffler that I believe would make a good resonator delete option though not as quiet as the Magnaflow Tru-X or the Dynomax It is also offered as an H-Pipe Edited September 19, 2022 by Xtra 1 Share this post Link to post Share on other sites
Xtra Report post Posted September 15, 2022 I forgot to mention all of them are 2 1/2 inch in, and 2 1/2 inch out so an adaptor would be needed to hook up to the OEM 2 1/4 inch exhaust. But I am looking at going to a 2.5 inch cat back res delete system anyway. Share this post Link to post Share on other sites

I had the MRT cat back on my Fusion sport and I wasn't a fan so I'm looking for other options on my edge. 1 Share this post Link to post Share on other sites

Hello Mustangvert91, As far as I know there are three off the shelf options at this time for the ST and Sport with the 2.7EB . 1. The MRT axel back system . Replaces the suitcase muffler. I have this on my car and when on the highway it is quiet, but as soon as you go up a mild incline on the highway a drone kicks in that I don't care for. the only way I can get rid of it is to downshift or put the car in Sport mode. On the other hand it does give a good aggressive sound when accelerating The link is tp MRT they can be found for less https://www.shopmrt.com/category-s/2331.htm 2. The Borla Cat-Back Exhaust System It is a 2 1/4 inch system that I believe will fit the 2.7EB Sport as well . The most expensive option. MSRP is around $1900 can be found on Amazon for around $1500 https://www.borla.com/products/ford-edge-st-cat-back-exhaust-system-140766 3. The aFe Vulcan Series 2 1/2in Cat-Back I think this will also fit the 2.7 Sport MSRP around $1100 I have seen it advertised on sale for around $875 https://afepower.com/afe-power-49-33133-vulcan-series-2-1-2-in-304-stainless-steel-cat-back-exhaust-system =========================================== 4. Custom make one to order at your local muffler shop Edited February 28 by Xtra 1 Share this post Link to post Share on other sites
