Right now on my first gen in running a RB streetable header -> a cat delete pipe with pick up tube -> a stock muffler(burned out bottom)
My idea was to put a flowmaster at the end but i was told not too because it would just burnout in a few months and probably wont sound too nice. and that its design cant handle a rotary's beat or something like that.
so i thought maybe a magnaflow or something of that sort? maybe one of the summit ones. i have heard good things out borla but they are pretty spendy.
Id prefere single in dual out. i really need this to be street legal because its annoying for one right now(noise inside the car), and i have neighbors complaining and cops patrolling my house(i honestly do)

 

I have a racing beat street header flowing directly into a dynatech split flow race muffler:

continuing through 2.25'' piping to a ebay dump tip muffler:

It is very loud at full throttle, but anything less is perfectly reasonable. Its actually one of the better sounding N/A 13b's I've heard at lower RPM's. It breaks up and gets really raspy above 4,000 though.

All told it was around $550 for everything with brand new parts throughout. Looks good, sounds good, and it was fairly reasonable to piece together.

 

haha well im looking to save some cash and only fabricate the tip for now. my dad has been doing most of the welding and is not going to weld up anymore pipes in between the header and mid pipe. so im just going to stick some sort of tip on it

 

Well then you're going to have one shitty sounding exhaust system.

 

If you use straight through mufflers, they need to be perforated core. The larger diameter the outer shell, the better. ("Bullet" mufflers are not mufflers except in name). Fit as many as you can under the car. Basically the exhaust should look like a collection of mufflers with a bend here and there.

I have had okay luck with fiberglass packed mufflers, they don't seem to lose their muffling qualities much after the packing blows out (takes about five minutes).

Using a 2.5" exhaust pipe, I stuff a 1 7/8" - to - 2 1/4" ID adapter into the tailpipe backwards. Does a lot of muffling and the exhaust is sufficiently cooled at that point that it is not a significant restriction.

 

the easy answer is to buy an RB rear muffler. everything else is going to be loud

 

Basically nothing your looking for will quiet it down enough to not be a nuisance. Just take it to a muffler shop and spend $300 and do it right.

 

i just want it to be legal. and not sound rattly like it is now. i'll try to get a vid of it now. i want it similar to how i had it with the single big cat and a homemade canister tip. it sounded gorgeous.
but i dont want to give up that performance. i had the perfect sound for absolutly free. just some time for the welds and all the piping was free scraps from my dads work

 

i can always probably fab something up myself if there are any suggestions. im sure with some guidance i can make an effective muffler.

 

Those three things are next to impossible to accomplish with 1 muffler. A big racing beat powerpulse muffler would bring noise level down, but you will lose power. A straight through magnaflow will see no losses, but it will be loud and raspy as hell. I have TWO mufflers on my car and it is raspy. Cat's do a large amount of muffling themselves, and your homemade tip probably did next to nothing.

 

i have a borla in mine, and it sounds awesome, but its way too loud.

 

the tip did make it a bit deeper and throatier. i tryed it different ways and it helped, it didnt muffle it just gave it a nicer sound.
And by raspy i mean my stock tip has the bottom burned out so the sound it makes while going throught the shredded metal inside of it. not raspy exhaust noise.
