My n/a super b3 build

[FlowmasterFestiva]

late but i know what a flowmaster sounds like on a 4 banger. i dont think its to loud but ive been told the 93 i had could hit 130 db with the flowmaster i had on it.

[drumnerd33]

Got a video? Asked matt about flowmaster cuz i like flowmaster but he said on 4 cylinders because of the firing order (i think thats what he said) it tends to have that raspy sound.

[FlowmasterFestiva]

its old and the car is very dirty. just an idle and rev vid i took while i was at work
only place i have it is on my old myspace as i wiped my old computer and forgot to save the vids and pics that were on it.

sounds great at idle imo. this exhaust got me an invite to the EMRA.

[drumnerd33]

Dual flowmasters... nice sounds pretty good

the muffler itself is a 1 in 2 out camaro muffler

neighbors didnt like it as i was up at 5am to go to work still have the exhaust but not the car. had then engine pulled to do a swap but lost my job and didnt have the money to finish it. then the township got on me about the car sitting there unregistered and all that so it had to go. it could get louder as ive scared a few with it it by hitting high rpms in a gear then letting off. not sure why it got so much louder by doing that though. im not as knowledgeable as most on here about cars in general though id like to be

[drumnerd33]

right on

rule of thumb is, if you want a low quiet tone with no rasp, get a muffler with glass packing in it, if you want a loud raspy as heck muffler, get one with only metal baffles in it... (open chamber)

on 4 clyinder engines, i hate the sound of open chamber mufflers on them..... but thats just me...

I found it strange that you were breaking it in nice and easy... I've always followed this method. http://www.mototuneusa.com/break_in_secrets.htm

Not disrespect intended, I've always used this way, excellent compression and ring spoke clearing up after the first half if break in.

Please post a WOT video... Lol

Re: My n/a super b3 build

I never knew about the packing vs baffle... Matt told me the same thing... The muffler I have on it now is a packing style just moving so much more exhaust it's still crazy loud... Its a neuspeed designed for vw cars I guess.. Lol my buddy gave it to me cuz he found it on the road.. Was brand new just scraped up cuz it fell off somebody's car, I looked it up and it was 250 bucks to buy one... I like the sound just need to cut it down a little, matt told me ha has a resonator a dyno max muffler I think, and a tune tip... The kind that has a muffler in the tip... And his is still loud as hell

Re: My n/a super b3 build

I did my break in according to Matt who built this head, he also builds race motors for a living, so I trust him.... He did tell me about how the honing process is different for engines now a days and that you don't have to do the break I'm like they used to... It used to be like drive it for 30 miles an hour on and off the throttle then a lite more and then do the 500... Matt told me to start it, Rev to 2000 rpm for 20 minutes, then shut it down an change oil filter only, then do 500 miles of normal driving just don't go over 4500rpm then change oil and filter and can drive the crap out of it and red line as I want to, then @ 3000 miles I can start running my synthetic oil.

Not trying to be mean or anything but kinda reminds me of the commercial where the girl says the Internet can't lie.... Then says her date is a french model.... Lol

Oh trust me, either way works. I was hesitant to try it for the very reason you wrote (Love that commercial)

However, I wasn't the first around here to do it. And remember, you're running a high strung n/a car with a static comp of what, 11:1? You don't get the dynamic comp that a forced induction app does so I'm guessing the 16G DSM I helped build that was 9:1 comp on 30psi with a high lift/low duration cam, may be a little harder on the rings. Motor that I'm speaking of put down 350awhp, has almost 35k miles on it since it was built, and compression varies by 1 psi peak to peak and still runs like a striped ass ape.

Again, not knocking Matt. I heard your car and it may be the sexiest 1.3L I've ever heard (excluding bikes, that isn't fair lol)

Re: My n/a super b3 build

For your muffler questions, contact Rich at Cone Engineering. He helped me build a muffler. Came out perfect.

Many people don't know that angles within the muffler change the sound. You can also have an internal chamber. The one I built had a flat entry chamber with a reverse cone exit. No rasp at all, and was a straight through with stainless steel packing.

about 3/4 of the way down, you will see a 4 inch round "magnapack" resonator. thats the same ones i put in aaronbrook37's car, it sounds awesome!!! at idle it sounds allmost factory and under 3000 rpm its VERY quiet... i put one close to this on another members car and it took away allmost all the rasp in his exhaust, a good resonator is the key to a nice sounding exhaust...

thats why its the only muffler i have on my car
