I have a mini van, and its got flip flop painted flames, really cool lights, and alot of other really cool stuff. But, it doesnt sound cool.
I have a stock engine, and stock everything. I want exhaust that sounds cool, i want a rumble with out that really annoying exhaust that all the forigen cars have. I've heard of a thing called glass packs, but i dont know what they are. If anyone knows how i can accomplish this, without spending alot, please let me know
to be perfectly honest, if its not a V8 you wont ever get the cool rumbling sound. a glasspack is just a staight through muffler with fiberglass packing that is popular because they are louder that stock mufflers and they are cheap. you can try a glass pack if you want but i dont think you will like the sound in a 6 cyl.
If it's done well vans still look good, just dont do the pimp my ride thing & put a flippin wing on it, ok? :P
Main thing, WHAT ENGINE??? Kinda need that info to get a better idea of what size pipes were lookin at here.
I'll give you a generic breakdown that should work well for a street driven 4-6 cylender engine. If it's got a V8, just bump it up to 3" all the way back.
I HIGHLY reccomend you get this done at a reputable muffler shop, have them do a full system for you & get a warranty on the parts. I do all my own work, but I still shell out the $$ to have the pros do things like this.
You'll need:
2.25" high flow catalytic converter
2.25" flex joint
2" x 24" Cherry Bomb glasspack
2" direct flow muffler
Have it plumbed all the way back from the down pipes to the tip with 2" pipe. The diameter is good to keep the gas velocities up which makes for good low end power, but big enough to breathe well for highway driving.
Mufflers:
Now if i remeber right, the van uses a myffler under the cabin & the pipe goes up over the rear axle & exits the side. Not much room for a muffler out back. I'd say off the top of my head you'll need something like this Magnaflow 5x8" offset oval
If the Mags are too $$, there's plenty of good muffs out there, just stay away from the wide open ricer knock offs & you'll be OK. A 2.25 turbo should be fine & will sound nice & mellow, yet have some thump to it.
My old '51 235 I6 makes a cool rumble, even with a stock manifold and just a Thrush glasspack. If it's got the 4cyl, it's gonna die soon ne way so ya mise well put the V6 in it, they are 3.3L V6's and they were used in the mini vans, they have an agressive rumble heard with even a stock exzaust, and the manifolds are seperate unlike V6's usally being a 1 peice, the exzaust is joined into 1 at the cat so, you could use 2 cats instead of a stock dual inlet single outlet cat. The stock muffler is quite literally half the exzaust system, they are about 10" deep, just under the van's width in width of the muffler, and about 1.5' long, and there held in with rubber grommits, you'll find enough room in there to run dual exzaust and put the mufflers where the big original goes. If ya wanted diffrent and cool, I'm shure you could shoe horn a 4.7 318 from a newer truck in there, and it should also mate to the tranny without a problem, then you wouldn't need to worry about mufflers, just run stock flow cats, they'll provide the back preassure needed to maintain the low end and they sound awsome like that, there pretty quiet at crusing speeds but, get on it and it's awsome, my friend has a '99 Dakota with the 318 and he removed the mufflers and left the stock cats ( V8 Dakota's have stock dual exzaust ).Quote:

sorry, inline 6's do sound good with a little throaty exaust, V6's -ehhh **)
fiero's exhaust has a nice rumble and it's only a 2.8. Worst thing I've ever heard was a glass pack on a saturn sc2
