First off, hello guys and gals (and those of you who are in between)! New member here from SC. I've used this site alot over the years for information, and that it surely has a lot of. I'm a member of various other forums across the vast regions of the intrawebs. I've read your forum guide lines, and am pleased with your site rules thus far.

I'm a previous owner of a ls1 4th gen Camaro (01' Z-28). I've been out the F-Body scene for close to 5 years now, so im a bit rusty, especially around the 3rd gen F-Bods. I've recently acquired a 1987 Iroc Z (305/Auto., 4 wheel disc, pw, so on and on and on, etc... blah blah), and i'd like to make the car a daily driver of sorts and kick it old school. Nothing is REALLY wrong with the car, needs some new rubber, some sway bar bushings, a LR brake caliper, and maybe a interior door panel.

What it really needs, is some NEW EXHAUST. It's equipped with stock manis, y, cat, and some joe blow "performance" muffler. I guess it sounds ok, but it isnt quite as loud/deep as what im used to. I know, i know, im used to a long tube, slp loudmouth, off road y LS1, and i know this is just an old small 305, but surely someone out there has found a nice sounding exhaust system for these cars. I'd like to install a set of long tubes, and since i live in SC, cats really arent that necessary.

So, whats everyone got to bring to the table?

 

Welcome to TGO mate! To answer your question, first off, replace the stock exhaust manifold (Which is very restrictive) with some headers (more sound AND power). Find a high flow muffler that you think sounds good and that's about all I have to bring. More engine mods helps of course, but the Header and new muffler first. Many people like Dynomax cause they are performace mufflers, sound great, and don't drone. They are not as "Loud" as some other mufflers though. Most people hate the flowmaster crapmaster stuff. There is also the mater of getting a better intake so that the TPI isn't crippled at higher rpms. That will allow for more flow and there-for a louder exhaust (correct me if I'm wrong guys, I'm still new too all of this).

 

TY. Has anyone tried Bullets either in single or true dual form along with full length headers and O.R.Y.? I searched youtube most of the night listening to clips. Some really nice sounding rigs using borla and magnaflow, but not enough specs on the car/engine/mods/exhaust system. A smooth low tone is kinda what im looking for.

 

never heard a 305 with longtubes before. Most guys run some brand of the shorties for these cars. I had a offroad y pipe, hooker 2055 shorty bolt on L98 with a single 3" catback with a single powerstick muffler. That was the best exhaust I tried on that car, but i've only had the flowmaster 80 series and a single straight pipe but with single cat still on the car. Straight pipe sounds like poop and is very loud. Powerstick gives the mean deep rumble I was after. A bullet is abit more smooth, sometimes with abit more rasp, and sometimes with a higher pitch than the chambered tubes, but they usually have a decent sound. They are just abit loud with a ORY, just like most 4th gens with loudmouths.

 

What is a powerstick? sounds like something Nintendo made in the '80s.

 

4th gens with loudmouth, ahhhh, now thats a name(er, sound) i've not heard in a long time. Think i just drooled a little there.

Why is it that longtubes are so rare on 3rd gens? I mean, yeah they're pressed for space, but all f-bods are.

Back to the dynomax, longtube convo. I found this. http://www.youtube.com/watch?v=_93-ig9Wvj4

Yes i know its cammed, but that car sounds quite lovely.

That's exactly why. I dont know why there would be more on 4th gens, but there's just no room for dual exhaust under these cars. I've got long tubes but I've got a trick Skulte crossmember that lets me tuck them up into the trans tunnel and I ran a 3.5 single out the back and over the axle.

 

Got any pics or a thread link vortex?

 

I guess manufacturers probably werent really catering long tubes to the 3rd gen guys either by making long tubes to fit. Easiest V8 header install ive done was my 4th gen with long tubes. My 81 z28 was harder to header than the 01.

 

Theres longtube headers ive seen for sale for our cars, but they cost more than a arm and a leg, and you still have to usually modify it to fit. There just more of a pain in a** for our cars. Plus not even a 1/2 of third gens ever built ( im guessing ) are running ls motors. Its all about your power goals and what runs best, and the older small blocks in our cars do respond well with shorties and they are much easier to install on 3rd gens which is why so many do shorty headers.

 

Power goals:
Short term- just make it sound good.
Long term - use that vortec i've got under the bench to build a 383 when i find an affordable, non cast crank, stroker kit.

 

The cost isnt that bad compared to what some headers cost for 4th gens My hooker 2210's fit just fine in my car, no mods necessary. Install went smooth since I dropped the motor in place with the headers laying in the engine bay.

Y pipes on 4th gens fit alot better than y pipes on 3rd gens when using long tubes. Thats the reason why most dont run long tubes. There are no complete "kits" that allow you to run longtubes with ypipe to factory catback exhausts like you do with 4th gens.

 

at least you are on the right track in building for the future.

 

Most people i see just run long tube headers do it straight back instead of doing a y pipe on our cars. I stand corrected then, i didnt know much about he 2210, just the 2055 headers from hooker. I myself am looking and searching for some headers for the setup im running now since i sold my other set.

 

Longtubes were best investment i ever made in my 4th gen. Noticeable improvements in sound (low rumbleand under-hood looks, along with slight performance gains. I had a set of pacesetter ceramic coated, that i bought 2nd hand off a friends wrecked car, they had less than 300 miles on them and were perfect. The only corrosion spots were on the bottom of the collector, where the collector met the asphalt a time or two.

 

I try, i try.

 

im running the stainless works long tubes from hawks. absolutly love em. i love the slip fit collector. ill never buy the 3 bolt flange style again.

 

will a set of big block sorty headers fit with the air box removed?

 

Personally, I love the sound of my flowmaster on my 305. I don't know why people "hate" it and call it crapmaster. Here is a video of how it sounds on a stock 305 with stock headers.

It sounds pretty similar to that right now. BTW, where did you get those tips from?

 

 

Ha. Funny how i log on right as you post that for me. Litteraly. You prob posted that like 15 sec before I got here. Did you take it to a shop to get that done or did you do it yourself?

 

SKELITOR117,
Just curious but what are you running for a exhaust ?

 

The place where I got the flowmaster installed had them. I forget the name of the place where I got the exhaust done honestly. I can find out for you tomorrow if you'd like since you are in SC, it was a place not to far from Camden. If thats to far for you though I'm sure you can find something similar, I seen a couple of similar tips just searching for rectangle exhaust tips on google.

 

if you havent you should listen to svandorst video on his magnaflow and cutout exhaust he just put his 92 L98. Its a good clean exhaust system, and when you get the 383 done it will have that beast sound you want granted with headers and the necessary etc...

Im more of a flowmaster guy since i have tryed both catbacks on my TA and out of preference i prefer flowmaster but to each his own everybody has different taste.

 

You know what, I'm a Flowmaster guy too. You don't hear me saying how "weak" I think some of the other exhausts sound in comparison. I spent allot of time searching for what I think is a great sounding system and to hear it being bashed is really getting old.

 

mw66nova did it for me. If you have a shop do it I'd provide a a Flowmaster y junction with the correct pipe diameters and a mufflex 3.5 inch or 4 inch exhaust pipe to them. Make them run dual 2.5s from your shorties in the stock route to a flowmaster dual 2.5 to single 3.5 Y junction and run that into a 3.5 inch pipe. You may want to provide them with mandrel bent pipe too. I see too many exhaust shop specials that are just terrible. The more good piping you provide the harder it is for them to slack off and cheap out on it.

With your setup, though, I think you should just run regular shorties with a decent y-pipe and a 3 inch catback though. I dont think you'd see any gain for the extra money/effort spent on a 3.5 inch pipe setup.

 

anybody have any idea if big block shorty headers will fit with the air box removed?
