o.k.
i went to Minekee today, to ask if there was a way to place true dual exaust under my 85. The guy said "no" anywhoot, i do remember there being a true dual exaust option, rpo code N10, now i'm curious about a few things.

1. How was the N10 exaust system set up?


then the others are about another option the guy gave me.

he could put a shorter straight pipe after the Cat, then a glass packed muffler or resinator, and a Y pipe after that which goes out to both sides, now, the guy said it was loud, my big question is, would it be loud like ricy or loud. My car at the present sounds like a 305 at low RPM's up till about 3k but after that it sounds like a 6, now i don't want v8 sound through all my RPM's, but if i could amplify the sound that i have down low, would this help it?

Oh, and also, i made a model of a 1982 firebird, the car has a single pipe, into the car, a single outlet, with a y pipe attached that then moves down to 2 mufflers, in the rear, is that the N10 exaust option? thanx all.

ok here goes

1 the N10 option was dual cats, not dual exhaust.

2 in my opinion, glasspacks rarely sound good. they are loud, but loud doesn't always mean good sound in my opinion.

3 on your 82 firebird. first of all are you sure it is an 82? cause the 81 and earlier cars had exhaust like that but they are of a different body style. if the car is an 82, the exhaust you described is not stock, it has been custom built that way.

4 if you really have to have true dual exhaust, talk to the other v8 guys and they can hook you up. otherwise i would get a performance muffler designed for 82-92 F-bodies. get one that has one in and 2 out(one on each side) that will give you dual tailpipes without true dual exhaust.

yeah the model is an 82 version, built in 82 even has a pic of an 82 firebird on the front. according to the packet it had two versions that could be built, one was stock and the other customized, the custom version had side pipes, and the stock version had the y piped 2 mufflers, but single i-pipe, kinda like the monte ss, except the mufflers were in the back like our long 2 outlet ones. My car already has dual outlets, and twin pipes, which i think looks nice, i'd just like to see the pipes come out without seeing the muffler. I'll go ahead and ask some v8 guys, thanx. Are there any others comments out there?

On the performance note, I know you can stick true dual exhaust under these cars.. from what I hear the biggest pair you can run is only 2 1/2" though... biggest single is 4".. not that any of us need exhaust flow in these quantities.. keep in mind, you only have a 6 and you do need a little pressure running through the system.

Glasspacks=Rice and Rice=

hey Hix, do you mean Rice at high RPM or rice down low too? just curious, also would a resonator be any different in sound, the guy said he didn't think i could fit a flow up that far, if worse comes to worse, i might just get a 40 series with dual outlets, with a highflow cat? but please respond to the previous

Down low the sound is just fake. There's no "beef" in the glasspack. At high RPM they are just way too loud, and still missing that (for lack of a better word) "beef". I like the throaty growl of a domestic small block. . However to be honest I have not heard what glasspacks sound like on a thirdgen, but I can't imagine i'd like it. It just conjures up too many images of sticker laden rice. but thats just my opinion.

The best sound you can get out of your V6 is to go true duel. Like I mentioned in another post it has a very distinct almost exotic, not ricy at all sound to it. I dont think most thirdgen V8's sound all that good myself, but again true duels make all the difference.

There won't be much of a performance gain with true duals as opposed to the single-in-dual-out muffler... especially on a 2.8. The larger the motor, the more effective true duals would be. Unless you really, really want true duals, save the extra $$ for another mod.

i agree, true duals on a 6 is kinds worthless since the motor doesn't need that much flow capability. i would just go with a dual outlet muffler and save your money for a v8!! lol (here i go again.)

superz, if i didn't know you were hopeing to get flamed, i'd flame you, but i'll just take it as good humor. Actually, i already paid a crapload for a new 2.8L, my former 2.8 went for 240,000 miles, how's that little 8 doing, j.k. anyway i wouldn't be doing it for a "mod" i just like the way dual pipes look versus the dual outlets on 1 muffler. I'm also sorry to say it, but i like the way the 80's and even 90's mustangs look with the dual, the way the pipes disappear infront of the fuel tank, that's how i'd have it done anyway. 3.1, do you have true dual? don't remember you ever mentioning that. OH, and my 2.8L does sound like a 305 until about 3000 rpms, after that it starts to become sixie, like it should. but i still want to keep my v8 sound down low, and if a glass pack with straight pipes will make my v8 sound just louder than it already is, i'd go for it. just want to keep hearing some discussion.

SuperZ, if you're going to agree with me, then pay attention to what I type:

I said there won't be much of a performance gain with true duals as opposed to the single-in-dual-out muffler. That goes for V8's and V6's alike.

Less of a gain would be seen on a V6- maybe 1 HP. A larger V8 would still see a small gain- maybe 5 HP. For all the trouble & cost of having true-duals installed, some other mod could be done for that price.

so what is your point?? i said that v6s don't need that much flow. i said nothing about v8s. i agreed that true duals wasn't worth it, and they aren't in my opinion. what else is there to say? i don't see where i misquoted you.
