A quiet performance muffler?

[jetvette1]

Does anyone know of a "quiet" and small performance muffler? I have 3" dual Delta 40 flowmasters on now. They sound great but I just moved to a "nice" neighborhood, and have already received a formal complaint (The guard at the gate made a visit on his -electric-golf cart). I am limited on space, the vehicle is a 77 cj-7 with a amc 401 and an edelbrock MPFI system. It currently has a T-18 in it but I may soon put in a T400. Space is my primary concern, I need them to fit inside of the frame. Any help would be appreciated, before a brigade of citizens armed with walkers and electric carts storm my garage!!!!

move where you can drive your shit in peace

r the flow 50 series is a bit quieter that the 40's

I've never heard these, but the name implies they might be quiet

the 50 series muffler is a good bit quieter than the 40 series. Post up what you decide. I'm in the middle of a small block chevy swap in my 81 cj-7, and am trying to decide on exhaust myself.

They're kinda loud. I have one between my skid and floor, keeps cool, though. My t-case was getting HOT before I switched to the hushpower. Kinda glasspack-ish, but without the raspiness.

Hush power is def not quiet. Im running one on a 4.0 w/ no cat and i can still piss people off when i get on it.

Magnaflow is a good bit quieter then Flowmaster.
Also try Spintech.

[rokcrwlrtj]

spin tech are also very compact

I'v got a 70 Series on my truck and it is very quiet (also made a big difference powerwise over stock) but it isn't small but you could run one instead of two.

[jetvette1]

I may have to go with a 70 series, it will be a tight squeeze, it will be tough bringing the two pipes together into 1 muffler. I,m running in-frame headers.

Sounds like you live in a shitty place.

If your able to pass a sound test right now, tell that guard to shove it up his ass cause your legal. If that gets you kicked outta the "hood" then really who cares... your paying a 80 year old man or a 18 year old highschool kid to play mall cop anways. We know he isn't doing it for free.

I had a 50 series on my jeep (and still have it if you want it). My glasspacks make better sound and arn't as loud, even dumping out under the doors on 2" pipe.


Can you not just put it in a higher gear and idle to your parking spot or something?

[jetvette1]

Well I think I may have to actually pay someone to do my exhaust. I will probably go to a Hi Po shop and tell them to fit the quietest muffs that they can, there may be room for a 70 under there. I'll research spin techs also.
BTW, the security guard is pulling down $22.00 an hour. Most of them are cops or Hwy Ptrl Officers on their off days. So I can't be to big of an ass. My vehicle has out of state plates, non smog compliant, and a dozen other minor infractions. This is one case that it may be better to be compliant than the example. I have tried coasting down the hill into the garage that works but leaving uphill, it trips car alarms from 5 car lengths away!

search mufflers on summitracing.com.... they let you filter your search by muffler dimentions, pipe size, inputs and outputs, etc

Nice cover. I remember that issue and thinking how'd that young buck afford that rig???


I'd say if your looking for something really quite, especially upon acceleration when going up your hill, the stock 4.0 muffler from a TJ is it . Maybe not HiPo , but it is quiet. Also, you can get on for cheap to try it out at the wrecking yard. good luck

[ErikFrancin]

does your current state have a noise law for mufflers?

seems like if it's legal in your state then the neighborhood would haev to accept it, whether they liked it or not. i ran into this in my neighborhood and it came down to the neighborhood having to accept it even though they didn't like it.


i'd look into running a single 70 series or a single magnaflow under the jeep if possible... generally speaking, the larger the muffler, the quieter the exhaust note...

Eric, when you still had a radio in your jeep, could you hear it ok ? I watched you guy's at Paragon for UROC on Sunday (finals), your jeep didn't sound that loud too me....
