denveratsun Posted August 21, 2009 Report Share Posted August 21, 2009 This is good stuff man! I appreciate the good feedback on this subject. I personally am running a Turbo muffler right now. The glass pack was way over the top for me...and it sounded just down right cheap.:D I am missing something from my exhaust tone though...and maybe this was the reason behind the thread in the first place. My exhaust sounds like it almost is cool...or almost sounds really good. It has gotten comments from folks and people say it sounds really good driving by...but I still want more. I want it to make the braaaahpbraaahppahhpahhhhb sound when I decelerate...and maybe even backfire once or twice...just a bit..:D Quote Link to comment
PEZi720 Posted August 21, 2009 Report Share Posted August 21, 2009 (edited) i'm gonna vote magnaflow... that's what i run... now yes... its not on an L series... but it sounds sick i don't have any real soundclips for you though... only this vid of me autocrossing and the sound was not picked up well...........at all its not technically a muffler though... its actually the round type stainless from magnaflow and the place i got it from labeled it as a resonator... so yes it is pretty loud with headers and no cat anyway... here's the vid... just remember it wasn't picked up well by the camera... but it sounds ok with decent speakers ">" type="application/x-shockwave-flash" width="425" height="350"> Edited August 21, 2009 by Phlebmaster Quote Link to comment
Phlebmaster Posted August 21, 2009 Report Share Posted August 21, 2009 (edited) Here is what I made when swapping out my exhaust system..it's an L26 but you will get an idea. :) Here is the swap from start to finish...you will hear 3 different sounds. :) The muffler I have is a turbo muffler...I still have it on standby.

Madness Posted August 21, 2009 Report Share Posted August 21, 2009 the sputtering a backfiring when downshifting is due to back pressure right? So a cross pipe or resonator will create that noise? Quote Link to comment
lynchfourtwenty Posted August 21, 2009 Report Share Posted August 21, 2009 my next mufflers are 2/3 chamber Turbo mufflers. noise are for kids your the reason i got my turbo muffler on my truck.. lol Quote Link to comment
bonvo Posted August 21, 2009 Author Report Share Posted August 21, 2009 well its sitting at the exhuast shop now its gonna have 2 1/4 from the header back threw a magnaflow its gonna have a flange welded onto the header so i can take it apart if need be now before people say that 2 1/4 is to big think about it the original exhaust was a almost 2 inches to begin with so its only about 1/2 to 3/4 of an inch bigger then stock the best part is the exhaust shop i took it to the owner has a 280z in the back that is one of his projects :D Quote Link to comment
lynchfourtwenty Posted August 21, 2009 Report Share Posted August 21, 2009 kick ass man, its gonna sound good, real nice low tone, an when u open it up... SMILES! :D Quote Link to comment
philip1 Posted August 21, 2009 Report Share Posted August 21, 2009 (edited) 2 1/4 is just about right for an L-20b any mods will make that choice sound even better. here is my wagon with 2 1/4 in header back no resonator ending with a Cherry bomb turbo and APC twin tip ">" type="application/x-shockwave-flash" width="425" height="350"> Edited August 21, 2009 by Phlebmaster Quote Link to comment
lynchfourtwenty Posted August 21, 2009 Report Share Posted August 21, 2009 well he's got a weber and a header so, ya it should sound freakin awesome Quote Link to comment
bonvo Posted August 21, 2009 Author Report Share Posted August 21, 2009 well he's got a weber and a header so, ya it should sound freakin awesome and it will eventually have some form of cam and headwork as well Quote Link to comment
heirfaus Posted August 21, 2009 Report Share Posted August 21, 2009 Yeah that will sounds great!!.....but 2 1/4 is too big. i went from 2 to 2 1/4 on my L20 and it felt like there was less low end torque. Look at all the V6 motors pumping out WAY more power than the L20b all running out of a 2 inch pipe, or 2 1/2 inch pipe. Oh well, have fun with it!! Quote Link to comment
b210in Posted August 21, 2009 Report Share Posted August 21, 2009 i'll be running a three inch exhaust with an 8 inch cherry bomb bullet (glasspack) in the middle and dumping to a ebay fart can in the rear. will see how it sounds Quote Link to comment
Cuts metal like mad Posted August 21, 2009 Report Share Posted August 21, 2009 (edited) Denveratsun! ...if you WANT it to backfire, go under there and drill a 1/8" hole in the exhaust pipe shortly after the header merge section, this will introduce air into the exhaust and cause the unburned fuel to ignite... most people DONT want this but, if thats what you want. :D Edited August 22, 2009 by zuum510 Quote Link to comment

Cuts metal like mad Posted August 21, 2009 Report Share Posted August 21, 2009 my 240z has 1.75" exhaust. 2.4L straight six... I will go up to 2-2.25", but thats all it really needs. Quote Link to comment

Backfiring is when your timing is off and you ignite the air fuel mixture with the intake valve still open and the flame front travels into the intake manifold. Not sure what the official names is but in Auto school the college instructors called it "afterfire". My car does this when ever I decel in gear down from at least 3000 rpm and I love it. But if I just kick it into neutral it never does it. I like to get up to 4K rpm and right when I'm passing a pedestrian I jump off the throttle and it's like fireworks passing them :D Quote Link to comment
datrod Posted August 22, 2009 Report Share Posted August 22, 2009 I think you made a good choice Bonvo. I run a 2.5" dia with magnaflow on my street Z, sounds really good. People always ask if I'm runnin a V8. On my race car I run 3" with a big ass supertrapp hanging off the end. It will make your ears bleed. :D The wagon I run 1.75" with a no name turbo and a fishtail tip. I like it. :fu: Quote Link to comment
DISLEXICDIME Posted August 22, 2009 Report Share Posted August 22, 2009 raptor its cheep and sounds good Quote Link to comment
PEZi720 Posted August 22, 2009 Report Share Posted August 22, 2009 . Not sure what the official names is but in Auto school the college instructors called it "afterfire".

But if I just kick it into neutral it never does it. afterfire is a proper term... a lot of people refer to it as popping as well. the lack of backpressure causes it to happen more frequently because it allows more oxygen to get in there and ignite the unburned fuel.... its a little more technical than that but that's the basics Quote Link to comment
Jester Posted August 22, 2009 Report Share Posted August 22, 2009 Phleb: What resonator are you running. That sounds dang good. Quote Link to comment
