Default Convince me to buy longtubes

i got mid RK sport headers. They do come down pretty far, t he collector is pretty much under the car. Kinda like shorty longtubes, if that makes sence, lol. Got them with a ORY pipe, bullit muffler where the cat was then dumped. So its deff. free flowing. Now convince me ill still gain with LT's. I can get coated Hooker's for $419.00. Now with the LT's, ill have 2 bullit mufflers bolted to the flanges then dumped. Its a strip car only basically, so im not gonna run a y-pipe. So will i still see a gain with the LT set up vs. my RK Sport set-up? What kind of power range/gain will i see switchin to LT's.

actually, you want the pipes to be a certain length for optuimum power. the trick is, take regular paint/nail polish, and put a steddy line on the inter pipe. go drive around and let it get nice and hot. right where the paint just becomes discolored(twards the cat will be black, at the rear end will still be white), thats an old racers trick about where to end the pipe/put the muffler and dump/ add an H pipe. It works pretty well.

anyways. Long tubes over mid lengths, not a huge difference, but you likely will see a gain.

the rk sport mid and good mids and basically the same design as the asm mids which flow just as good a lts.so its you call i wouldnt spend the 500 extra bux for a couple extra hp if any. also the rk and asm mids have 1 3/4 primaries just like most LTs

IMO you don't have the mods to justify going to a LT.

Buy the LTs or I will steal your car.
Just kidding.
I bought some FLP LTs a while ago. I love those things. It changed the exhaust note up and made my car sound alot meaner than before. I had thought it sounded ok before but after the LTs man it sounds good. I felt a huge difference over my stock manifolds. I had cleaned up the entry ports of the manifolds with a carbide porting tool so I assume that they flowed alittle better than stock.

I dont know how much of a power gain I achieved, but now I just need to hit the throttle just a bit and the tail will go waggin. The engine wants to keep going once I get up close to 5K rpms.

Cam, heads...
IF you didn't have headers on the car already I'd definately
reccomend LT's.
I switched from a shorty to a LT with no other mods.
Picked up .001 and .1 MPH. Not worth it.

was this with an LT1 or a LS1 because they are two totally different realms as far as head flow.... Not trying to call bullshit or be a dick for that manner but I highly highly doubt that out of a bone stock LT1 with a stall LT's CAI and 3.42's unless you have a major factory freak car....... if it is an LS1 I believe it..... I have seen what LS1's can do with just bolt ons.... wish the LT1's heads flowed so well stock

Dont listen to SLOWMOFO, he speaks the truth. Longtubes suck. Stay Mids.


If you have a V8 of any make, you must have LTs!

agreed if you have stock manifolds go LT's without a doubt unless the car is lowered...... goiung from shorty/mids to LT's I wouldn't waste the money unless you are going with aftermarket or ported stocker heads and if you are getting the heads obviously you are going to get a cam.....

Lt1...my Bolt on ls1 car runs 12.5's with smaller gears, and smaller stall

My friends bolt on LT1 ran 12.7's, with a th350, full suspension (hals on all 4)and a 12 bolt. N/A and 11.5's on the jug.

Then he added a small nitrous cam, gasket matched the heads removed a bunch of weight and has run a best of 11.8 n/a, and 10.9 on a 150 shot.

Lt1s are faster then most think

I didn't mean to doubt you but by how you put it before it sounded like there was no suspension work and stock trans and rearend... i'm gonna guess that he has the car tuned as well and is on a sticky tire

sticky tire yes, but cars still on the stock tune and runs real rich. He runs a dry kit so he doesn't care.
