I really love my new additions. After replacing the 20 year old cat and destroyed flex pipe and putting a mangaflow muffler (magnaflow cat as well) I cant describe now happy I am. I payed 160 for 400 dollars of parts (shipping included). So I know this is full of really bad grammar but I just got back from the shop where I had to go and re clamp everything. With the last of the leaks fixed all I can do is : D The sound it makes once it hits t-vis makes me almost cry of joy, and with my restored torque and maybe a few more poneys I can hit the gas at 4K in first and it lights up the tires. in addition I also cut 2 inches off the shifter, and lubed up the gas padal and lines and it just drives a lot nicer now, don't have to force the pedal down and deal with it sticking slightly oh and i just got 30 mpg out of my last tank, its a good day... Sorry for the positive rant!
I was thinking about doing this same deal, which magnaflow set did you buy? I am really curious to hear what it would sound like... I bet it has a nice little rumble? My friend put a set of cherry bomb mufflers on his 200sx, and it sounds really nice! No high pitched whiny sound, like you would hear on a normal import! I really want to do this, pull up to a stop light, and mash on the gas, and see reactions!
I got universal parts and fabricated them on. The car is borderline ricey till tvis kicks, then the tone changes to sweet godlyness. Not a fart can, but if you want to hear it more or less, just take the muffler you have off, then imagine it a quieter. I took my muffer off (the magnaflow) and ran the car and it sounded almost as loud :$ http://video.cardomain.com/Clip.aspx?key=1B06B22975B5B818 theres a video of it when it still ahd a small leak. the soudns quality isnt very good
I'm working on my new exhaust 3" Aussie DP. with an electric cutout 3 inches after the flange on my mid pipe (so I have room for tools LOL) Muffler is a 3" one off of a truck LOL I wont be using it any more! MUHAHAHAHAH! On that note, I have an Aussie Midpipe and HKS Silent Hi-Power Muffler w/resonator for sale...
I have always been wondering, will any muffler create the needed back pressure that our cars need, as long as it mates up to the pipes? If that is true, I definitely want to get one for my car... I have a different engine than you guys though... Just a lowly little 3sfe... My car actually sounds cool, but there are holes in the muffler... lol Gotta love how nature creates awesome sounds!
I dont know about this "needing back pressure" I know you don't want to run 3" pipes but I know a high flow muffler increases both hp and toque slightly. Maybe its a difference between pressure due to pipe size, and pressure due to restrictions. My exhaust varrys between 1.75 and 2". I think reducing restrictions in the cat and muffer are similar to expanding to 2.25"
screw back pressure. you want your exhaust gases to move out as fast as possible, It helps create hp because of the scavenging effect it has on cylinders. You need a header to exaggerate the effects aka make more power. Too big and you will slow down the exhaust velocity too much and lose more power than you started with.
Please someone correct me if I'm wrong, I thought you HAD to keep the flex pipe since the motor moves a little and if you remove the pipe, it will break motor mounts. -K
