GI.SS Posted June 18, 2013 Report Share Posted June 18, 2013 Few months ago I installed my headers. The collectors are 3" that reduce to 2.5" Current exhaust is 2.5" back to the 22" magnaflow. I like the sound that I have. It sounds flat mean at WOT and isnt too loud. Currently no Cats and it exits stock location. After the header install, I had to re-do my Y pipe and well any of those that have tried to cut up their stock Y to make work knows how much fun I had. Along with a POS flux welder I borrowed from my neighbor. Lets just say she has a little leak in a FEW places. I have read that to have proper backpressure 2.5" is good to 600hp. After 600 then you would need to move up to 3". I would also like to run the muffler I have. Mainly because Its a performance peice I already have and have acquired an taste for it.I would like to do 2.5" exhaust from collectors back. Should I run an x or h pipe? The muffler is DI/SO I thought the muffler might even pressures out. I also am having a custom tip made, if anyone is familiar with the "boom tube" which nascar uses. Tip will be made out of polished stainless and with be SI with a slash cut boom tube replica that has a baffle in the middle to look as if 2 tip were welded together. Still trying to figure out how big but it will be tucked before passenger side rear tire. Anyone running the 22" magnaflow with cats and headers? I wonder how much quieter it will be? http://www.google.com/imgres?q=nascar+side+exit+exhaust&start=73&safe=active&hl=en&biw=1600&bih=704&tbm=isch&tbnid=LDIxq3ljOBFd6M:&imgrefurl=http://forums.tccoa.com/showthread.php%3Ft%3D121401&docid=bsOU-xrskTFw5M&imgurl=image.musclemustangfastfords.com/f/9161940/mmfp_0710_10_z%252B2006_ford_mustang%252Bside_exhaust.jpg&w=640&h=480&ei=w0vAUZewD5fG4AO-_YCQAw&zoom=1&iact=hc&vpx=220&vpy=378&dur=1984&hovh=194&hovw=259&tx=152&ty=123&page=3&tbnh=146&tbnw=210&ndsp=40&ved=1t:429,r:6,s:100,i:22 Quote Link to comment Share on other sites More sharing options...
onebadmax Posted June 18, 2013 Report Share Posted June 18, 2013 I know I'm in the minority here, but LTs, with no cats, sound pretty damn good through the factory muffler. Quote Link to comment Share on other sites More sharing options...

JC03SS Posted June 18, 2013 Report Share Posted June 18, 2013 I have longtubes no cats dual back to a dual in out magnaflow. Love it. My muffler has a built in x. If you take the y off I say x pipe it. That's what I would do. Quote Link to comment Share on other sites More sharing options...

JC03SS Posted June 18, 2013 Report Share Posted June 18, 2013 I think it will flow great. I also have mine turned out before the rear tire. Quote Link to comment Share on other sites More sharing options...

Aldofashow Posted June 19, 2013 Report Share Posted June 19, 2013 (edited) Arh 17/8 LT no cats 3" all the way through 4" magna packs dumped out before the rear tire on the passenger side true dual no problems Edited June 19, 2013 by Aldofashow (see edit history) Quote Link to comment Share on other sites More sharing options...
ballincustoms Posted June 19, 2013 Report Share Posted June 19, 2013 Mine longtube headers 3" dual pipe and dual cutouts with x-pipe no cats, dual magnaflow muffler and dumped before spare. Not my setup but came with my truck pretty mean sound. Only reason I know this is i researched the ss for an exhaust setup on my 99 silverado loved the sound Quote Link to comment Share on other sites More sharing options...
Joe Roknic Posted June 19, 2013 Report Share Posted June 19, 2013 I love mine too. it just leaks too much. maybe take it too a muffler shop and have the leaks fixed... or grind out the welds and re do them with a better welder Quote Link to comment Share on other sites More sharing options...
GI.SS Posted June 19, 2013 Author Report Share Posted June 19, 2013 Ehh not really worth the time fixing it. It would be quicker to just create a new one. Thought I'd prolly have an exhaust shop do it or myself with the right tools. The problem with exhaust shops is they never do it the way you want them to l. I could even just re do the y pipe and exit exhaust where saw fit and it would work well. Hmm gotta think about this one Quote Link to comment Share on other sites More sharing options...
