ZXMustang Posted April 2, 2010 Report Share Posted April 2, 2010 my magnaflow exhast is not doing the trick! any ideas on what i should buy instead?? Magnapacks if you already have an offroad X pipe, or if you dont, then get the magnaflow muffler deletes. Thats the hot setup. Link to comment Share on other sites More sharing options...
69machl Posted April 2, 2010 Report Share Posted April 2, 2010 Yup-- Muffler Deletes. If you want louder that what you want. I pondered it for a long time and the magnaflow deletes are what i got. I worried that they were going to be too loud. they aren't. you'll be happy with them. Magnapacks if you already have an offroad X pipe, or if you dont, then get the magnaflow muffler deletes.

10random Posted April 2, 2010 Report Share Posted April 2, 2010 my magnaflow exhast is not doing the trick! any ideas on what i should buy instead?? Which Magnaflow's are you running? If it is the full muffler, then you will want an off road pipe. It is really hard to beat the sound of these mufflers paired with an off-road pipe! If you can get away with it...otherwise go for the KR mufflers. Link to comment Share on other sites More sharing options...

moburto07GT500 Posted April 3, 2010 Report Share Posted April 3, 2010 I have the Pypes 'Pype Bomb" muffler delete, it is similar to the SLP "Loud Mouth" just cheaper. I got mine for $220, they look good and i didnt have any fitment issues. My exhaust is completely stock other than these, and I highly recommend them.

cubican Posted April 4, 2010 Report Share Posted April 4, 2010 The Roush extreme mid muffler set up is just bad a$$, and 100% no drone. they sound much better that any of the deletes. Link to comment Share on other sites More sharing options...
MikeCMM Posted April 4, 2010 Report Share Posted April 4, 2010 Mine are still stock but I found this to be of help from MrFarmdog. It might give you a better idea of the sound you're looking for. Good luck! M Link to comment Share on other sites More sharing options...

Mike Mike, April fools is on April 1st... SLP Loudmouth have no drone...? That's a good one... Now back to reality, I've had them, and they were one of the worse droning, I repeat, worse droning set-ups of all. I did love the sound of them though, just hated to have to keep going to the dentist to have my fillings replaced because of the interior resonation. Look up "drone" in the dictionary and there will be a picture of the SLP Loudmouths next to the word. I'm not busting on your exhaust, I already said that I loved them, but...

monsta Posted April 4, 2010 Report Share Posted April 4, 2010 I have Flowmaster 1 chamber race mufflers with stock cats on my 09' gt500. I wouldn't want any other muffler. They SCREAM when you want them to, and quiet when you don't. Link to comment Share on other sites More sharing options...

tomhoulihan Posted April 4, 2010 Report Share Posted April 4, 2010 You need the KR'S ....They rock! Start with the stock Xpipe then if it needs it go with the Hpipe! Hello. I have installed the "H" pipe along with KR mufflers. The sound is wonderful, very retro. No drone. I LOVE it !! -Tom Link to comment Share on other sites More sharing options...
Snake Doc Posted April 5, 2010 Report Share Posted April 5, 2010 You need the KR'S ....They rock! Start with the stock Xpipe then if it needs it go with the Hpipe! +1 Not only do they (KRs) sound awsome, but Ford says they're legal in 50 states. I hear drone around 1k rpm but hardly ever spend any time at that rpm. I had the SGTs or 5GTs (don't recall which) and they sounded great but had objectionable drone at 1800 - 2000 rpm. I have the KRs with the "PowerHouse H" pipe. Good Luck & Good Hunting! Link to comment Share on other sites More sharing options...
FiaCobra Posted April 5, 2010 Report Share Posted April 5, 2010 my magnaflow exhast is not doing the trick! any ideas on what i should buy instead??

mustangman66 Posted April 6, 2010 Report Share Posted April 6, 2010 my magnaflow exhast is not doing the trick! any ideas on what i should buy instead?? SLP Loudmouths for me. Here is a video of mine in action. The Roush offroad extreme systems sounds awesome as well. If you want loud without removing the cats I would definataley go with some sort of muffler delete.

jcthorne Posted April 7, 2010 Report Share Posted April 7, 2010 Borla/FRPP Stingers and SLP Loud Mouths come to mind, but get ready for some drone... I have had the SLP loudmouths for better than 3 years. They sound terriffic and DO NOT DRONE. At highway speed they are not loud at all. I also park the car in a basement garage in a professional building. If they were really loud I would never have kept them this long. They are a bit sharp in tone when the cats are cold but really mellow out once the cats light off. Been very happy with them and the tips look great, even 3 years later.

frazierfreud Posted April 9, 2010 Report Share Posted April 9, 2010 keep your magnaflows and add some long tube headers. that really woke up my magnaflows. the sound is great...very loud when you put your foot into it. plenty of volume at low rpm as well. plus, a little more hp is a good thing!

SicShelby Posted April 9, 2010 Report Share Posted April 9, 2010 Where did you get the cut-off system? Is it like on the the vetts? After a LOT of looking, I got < this kit > from RaceReady because they warranty the cutouts for life, whereas the competitors product is generally only warrantied for a few months, or so. The 'Vettes use a certain dual chamber exhaust that opens up an extra chamber under certain spirited driving. The y-pipes either strap or weld into your existing exhaust, and the cutouts mount to the y-pipe. Mine are electric, so when I press the button to open them, it opens the cutout (which is kind of like a throttle body) and allows the exhaust to flow out the y-pipe. With them closed, the exhaust runs its normal stock path through the mufflers. Click on one of the < videos in this link > to get a better look see at what they do. Here's the switch (above the ambient lighting button). So if I want loud, I press down and they open, and if I want quiet I close them. I can also have them anywhere in between.

Poisnus Posted April 12, 2010 Report Share Posted April 12, 2010 I just added the KR mufflers this morning and the sound was exactly what I was hoping it would be. It really gives the Shelby a attitude adjustment over the factory mufflers. I drove the car out of town today and put about 90 miles with the KR's. At interstate speeds, 70-80 mph there is no drone whatsover. The only time I noticed a little drone was at a very low rpm but nothing to me as my daily driver is a 6.0 Powerstroke with a straight piped 5 inch exhaust.
