hay everyone,looking to run long tubes w/o emissions crap,any suggestions? only mods i have are a 305 to crate l98 swap and got rid of a/c,not looking to do alot of cutting or anything basicly looking for long tubes that will slip right in(with custom pipe to the back of course) any help would be grate and pics would be good to thanks

 

auto or T5?

 

says 700R4 in his profile, long tubes would be a tricky thing to do

 

ls4gxp: yes it has the stock auto 700r4

twin_turbo:what would be tricky? i've heard of the trans cross member getting in the way,if thats so what if i used a double hump cross member?

 

The whole tranny is in the way, much less room w/ an automatic than w/ a T5 or even a T56.

There was a brand that had full length swept headers that route along the oil pan and to the side like the factory Y pipe. I think it was Hedman but not sure. Anyone know what brand/part number they were??

 

i dont know if anyone would agree with me or not but you didnt mention you had any mods, just a 350 swap. If its a stock 350 swap why go through all the money and headache to swap to a longtube and lose clearance? I would think unless your fully modded running 400+ hp theres not gona be a whole lot of difference with longtubes. Buy the time you buy the longtubes, and spent all the money on custom fabbing the exhaust to make it work, just buy a set of dyno dons shorties that have proven to flow well enough to make over 500hp on motors. There an exspensive header but in the long run am sure its cheaper then longtubes $300+ and all the custom work on the routing.

Only other option i could see is this. My friend had longtubes and routed is exhaust system just like the old school 2nd gens, placed the mufflers right behind his back front seats with turndowns. He upgraded the suspension with coil overs in the back which helped raise the cars rear end with taller tires. It was a stiff ride but he had no clearance problems what so ever. It had that drag car look, rear raised and front raised just a tad, looked real sweet. He never once had bottoming out problems in driveways or inclines. I believe it was an auto also. It sounded amazing aswell, were junk edelbrock headers with flowmasters, not sure the brand but they were thin box shaped. I could hear him cruising down the road 1/2 mile away off the throttle. He can that on a pretty much stock 305 that i think ran 16's lol You would have thought the car was a 10 second car the way it sounded tho.

 

yeah my profile dose not list mods because all i did was swap to a 350 crate motor,i believe its supposed to be a replacement motor for a 65 s10 i got it from the dealership,and i pulled the a/c but replaced the compressor with an a/c delete pulley,other then that all i have done is dress up (taller valve covers and an edelbrock open side air cleaner with a k&n filter,and i got rid of the cat' and put a flowmaster 44 in place of the stock muffler) i dont consider those that major sense their not that big of changes even the exhaust is still only 1 pipe from the Y but yeah i'm trying to stay away from shorties sense i plan to do a lot more modding like s/c bore/stroke,new heads....the works,plus i think long tubes sound better,i'm just trying to avoid cutting anything for now,and i have a buddy that dose custom pipes so i'm not worried about the cost of that kind of stuff,and i'm not concerned with clearance sense i'm going to totally redo the suspension and everything,i'm basicly slowly turning the car into a street/strip car,thanks agine for all the suggestions,oh and ls4gxp,did your buddy have to cut anything when he installed his headers?

 

If you have an Auto the ground clearance is really going to suck as you will have to run the tubes under your trans crossmember and cant run the pipes straight down the center of the trans tunnel. T5 are lalot smaller then Auto's.

There thread and threads here on the board about longtube installments. My friends was the first ive seen ever routed as the mufflers stopped at the end of the trans with turndowns. for being almost stock 305 it sounded like a 600hp car. I smoked him in a bone stock 89 formula 305 tpi by car lengths.

Your saying you want longtubes because of your future goals of power adders and sound. From what everbody says here the difference in power is slight feel in the pants. Dyno Dons shorty heads on same motor as longtubes only produced 10hp less. And i think that was with a 500+ hp 400sbc.

Save the extra few hundred dollars on custom work with longtubes, save the extra weight your going to be adding with more pipes, buy a full 3 inch or 4inch exhaust, best shorty headers made ( dyno don ) and put an electic cutout where they Y pipe goes, should be plenty off exhaust flow for 500+HP.

Going to stuck ruining the nice longtubes when you scrape on the high inclines of gas stations, hit bad pothole, or parking in driveways.

Search the site for longtubes, plenty of pictures here on the site, Plenty of poeple saying they went longtubes to shortys because it was so ridicolously low

 

thanks ls4gxp i will have t look around the site see what i can find,and about saving on the pipe...i'm going to redo everything piping is going to be one of those seeing as how almost my whole exhaust is rusting through and needs to be replaced anyway i figured i would go duals with cherry bombs or a good sounding flowmaster and my buddy that will be doing the exhaust has done a 1989 rs and showed me pics and he had no clearance probmlems and ran both pipes over the rear end so there were no issues in the back and he did cut outs just after the long tubes/befor the mufflers so it was some what quiet on the road and he could open the cut outs on the track...he said it sounded mean both ways,but again thanks for the ideas

 

Same firend ran trual dual routed same diection of the stock exhaust. Ran 2, 2 1/2 pipes along the passager side of the car. Wheres the cats are he put 2 cherry bombs there, ran the rest of the pipe to the rear and had them exit the center of the bumber, Sounded mean as hell, but again he ran shorties. So theres room to run 2 pipes on passenger side aswell.
But believe me, 2 cherry bombs, no cats, is a very obnoxious car, exspect ALOT of tickets for noise. His car only ran mid 13's. If your planning 500+ like my build, i couldnt imagine how much lowder it would be. Stay away from flowmaster, louder doesnt mean faster, magnaflow is the way to go

 

thats sounds like it would look pretty cool to,why magnaflow? do they flow better? i'm not just looking for loud i'm looking for deep rumble and loud,i'm not worried about noise cops in sarasota florida dont care about that,they only give tickets for the big getto speaker systems,theres a guy that lives up the street from me with a 67 maro ss with over 1000hp and he drives it on the street all the time(its actually ment for draging and hes got true duals on it) and he dosen't get any tickets

 

he probabbly has QQ plates and that why he gets away with it. Magnaflow is the best cfm flowing mufflers out there. Flowmaster are the least flowing exhaust.

If your pockets are deep and you dont care about scruffing up the nice longtubes then get longtubes. I you want loud, plenty of clearance, theres plenty other true dual options to go that sound bad ***.

 

i did not know flowmaster was that bad....what are QQ plates?

 

QQ plates are cars registered through DMV that are over 25yrs old. No emissions, and am pretty sure they dont need inspections, aslong as they have all essentials of being street legal, ( signals, lights, brake lights, etc. ) When your car is QQ registered your only allowed certain mileage a year. Something small like 3,000-5,000 miles a year.

For example, If you see and OLD muscle car, camaro, firebird, cuda, yatta yatta and there blower is sticking over the roof of there car and is loud as anything, cops tolerate it because of the QQ plates.

Do a search for cfm flow on flowmaster and magnaflow, aswell as other exhaust, For a comparison power wise i would say a fowmaster is a 305 sbc and a magnaflow is a 383 sbc lol magnaflows flow soo much better and free up more power.

Can i ask why again you prefer longtubes over shorties? You planning on 600+hp later down the load and 10+ to dump in the car?

 

i don't think he has QQ plates he just has a regular florida plate and he dosen't have a blower or turbo its all motor no nos eaither,oh and preference to long tubes is mostly look and sound,but i've also heard they flow a lot better then shorties....shorties are starting to grow on me though

 

like mentioned before, seeing you have an auto, to run longtubes its gonna cost you alot of money and alot of fabrication. If your not planning on building a high 500hp+ motor theres reallly no need for it. You can get the loud and flow from shorty headers, Dyno Don has proven that time and time again with his style. The difference in longtubes and his header numbers werent off by all that much. And to affect the sound also has to dea with what parts you have in that motor. My 2 Cents is save all the money on a custom longtube header and put it in the valvetrain and motor and you will be very pleased. Loud doesnt only mean faster. Only ricers think that

 

Dyno Don headers are the only 1 3/4in shorties headers made for our cars except for SLP 1 3/4in. That test you were talking about it was on a 368cuin motor. The difference was about 4-6hp across the board.

 

hahahaha i like that ls4gxp...i never did understand that about ricers, why do they think making their car sound like a p!$$ed off bee or a weed wacker sounds good?,and agine is there a place like summit or jegs that carries dyno dons?

 

You can find Dyno Don on the Socal board. Or go to www.socaltpi.org and or pm him for any question you may have. I go to his shop all the time when I can and I know his work. 95% of the thirdgens he builds are using his headers and there are no complaints. Best bang for the buck. His headers will fit any type of small block heads that are out there and you will excellent spark plug clearance.

 

I ran long tubes on my 92 305 auto, from the collectors I simply turned the pipes out towards the doors and ran my pipes and straight thru mufflers in the channel under the doors, then turned them slightly outward in front of the rear tires. Almost like the old school side pipes, only you cant see the exhaust unless you bend down. Painted everything black except the outlets. No clearance problems ever, and an amazing, drag car sound! Cost was the price of the headers (I put them on) and 200 bucks at a custom exhaust shop.

 

nice toddo,what size pipe did you use and do you have any pictures?

 

If I remember correctly, it was 2 1/4 pipes. No pics, I don't have that car anymore...I upgraded from a 92 camaro 305 auto, to a 92 firebird 305 auto

 

QQ plates must be a Jersey thing. Here all you need to do is pass the saftey and emissions test. If the car came with any emissions equipment it must be on the car. If you have an pre-1973 of 74 cars didn't come with it so we can do what ever we want.

Longtubes are not going to help creat mega HP. Like everyone else has said go with these. Dyno Dons headers--> http://www.top-downsolutions.com/ind...41d5a1854524f2
