wfl_colorado Posted July 29, 2006 Share #1 Posted July 29, 2006 I am in need or replacing my exhaust, resonator and muffler. Anyone have any input or ideas on this? I know I can just go to the muffler guy and take what they offer, but wanted some input from the z experts. Any info on magna flow, vforce, etc. Or do I just go get a simple exhaust and muffler setup?Tx,Bill Link to comment Share on other sites More sharing options...
Hrududu Posted July 29, 2006 Share #2 Posted July 29, 2006 Mine is just a 2.25" pipe all the way back to a flowmaster 40 muffler on the back. Nothing special, but it sounds really good and seems to work just fine. Cost me less than $200 for all parts and labor last summer. Link to comment Share on other sites More sharing options...
mars23z Posted July 29, 2006 Share #3 Posted July 29, 2006 There are several threads with different exhaust set ups but if you you want a sigle exhaust the dynomax mufflers sound good to and they are only about $40 If you want loud check out the twice pipes at motosports auto http://www.thezstore.com/page/TZS/CTGY/PEC Link to comment Share on other sites More sharing options...
beandip Posted July 29, 2006 Share #4 Posted July 29, 2006 Bill , you didn't mention what else you are running . For a stock L-6 , a 2 1/4'' system is maximum is size . Larger will lower the low end torque. At least this is what I have been told and what I have experienced . Having said that I am running 2 1/2 '' mandrel bent , but it was free so I went with it . In time I will replace it with 2 1/4 '' . I prefer the Dynomax muffler super turbo. It breathes vary well and has a great low sound . I personally do not like the raspy sound of exhaust systems. For a resonator I recommend a Thrush glass pack. They have a perforated inside pipe instead of a louvered one . Louvers restrict the flow . My engine is mildly built . It's a ZX 280 with mild head work and a warm street cam and headers . And again for my setup a 2 1/4'' would be the best. In my view . Some back pressure is needed for good flow and scavenging effect. The larger piping is for top end HP. If you are into racing on the track and need to keep the engine spooled up to the high revs of a hot cam , then the larger plumbing is in order . I know there will be differences of opinion here , this is what makes this web site interesting. Gary Link to comment Share on other sites More sharing options...
sakijo Posted July 29, 2006 Share #5 Posted July 29, 2006 I don't have a Z, but the engine is the same. Gary is right - what else are you running? I have a really mild cam on an otherwise stock engine. Headers and a stainless Fujitsubo system is what I'm using. The headers are three into two and the exhaust is a true two-pipe system. Future upgrades are twin Hitachi SUs. If you're running stock, I'd recommend headers and a low-restriction muffler. Link to comment Share on other sites More sharing options...
wfl_colorado Posted July 30, 2006 Author Share #6 Posted July 30, 2006 Stock L24 in a 73 240 w/ SU's. The exhaust at the muffler is rusted through and the muffler is just hanging. No header that I know of, but would like to look into one.Tx,Bill Link to comment Share on other sites More sharing options...
vtdds71 Posted August 3, 2006 Share #7 Posted August 3, 2006 I'm trying to find the best complete exhaust system for my '72 Z (pretty much stock 4-speed, and no big plans for modifications to engine, etc.). I did receive a coated 3 into 2 header and super turbo exhaust from MSA, but am concerned because 1) the mounting flange of the header has a slight warp to it from front to back (MSA says that's normal, and will straighten out when bolting it on (?!), and 2) the rest of the exhaust is 2.5" w/ no middle muffler or resonator, just ending in a Dynomax muffler. I've read many threads complaining about 1) poor fit of these systems (MSA says they've improved them lately), and 2) heavy droning at certain speeds due to straight-through large diameter pipe. I also considered the Monza system from Black Dragon, but they cannot promise they will ever again supply the headers, so that's out. Plus, I have seen many people complaining about poor fit and quality of Monza/Pacesetter systems. Any suggestions? Link to comment Share on other sites More sharing options...
Arne Posted August 3, 2006 Share #8 Posted August 3, 2006 Find a good local shop, tell them what you want and have them custom build it. Ask the local muscle car and hot rod crowd who does the best exhaust work, and go there. You will get a better fitting system, they can help you select the proper system for sound, and the price will be about the same as the commercial systems.

=Resurected280= Posted August 3, 2006 Share #9 Posted August 3, 2006 No too sure what your personal tastes are but IMO glasspacks sound really good on Z cars. Can get pretty loud though depending on what setup you go with. Do a search on it, theres alot of info out there on that one. Link to comment Share on other sites More sharing options...

Plus, I have seen many people complaining about poor fit and quality of Monza/Pacesetter systems. Any suggestions? I thought the 6-2 MSA header was the pacesetter header. If that's correct then you've already seen the fitment issues firsthand. I wouldn't install a header that had a visible warp on the flange. That's just crappy production IMO. I have the 6-1 header from MSA (bought from AZC, but the same thing) and it isn't great either. I had to weld on it before installing because the flange didn't entirely cover the #6 exhaust port. It had a built in leak! Basically I have come to the conclusion that all of the cheap headers for Z's are crap, and that you need to step up to Nissan Comp's header before they really start to be worth the hassle. I have 2.5" exhaust with mandrel bends and a Super Turbo, no resonator. It wasn't too loud for me, and mine had a specific rpm range where it really got boomy, I'd say from 1500 to 2000 rpm. I don't normally drive the Z in that rpm range though, so it didn't really bother me. Drove it daily that way for 5 or 6 years, never did have a stereo either...

Midnight-280Z Posted August 20, 2006 Share #11 Posted August 20, 2006 i am running 2 1/2" exaust all the way back to a magnaflow 2 1/2 muffler (no cat or resonator) with no mods to the car yet except CAI intake (cheapo ebay). Car is really loud, but awesome at idle. going to add a resonator to reduce noise, my car vibrates around 2-3K not ricey sound either. but too loud for me. anyone know if i should got with a 2 1/4" resonator or 2 1/2" resonator? noise is tooooo loud for me right now. looking foward to installing my NISMO performance headers next week. =) Link to comment Share on other sites More sharing options...
