The effort is pretty much the same if you go with Pacesetter long tubes, so the work difference is minimal. Also, these get decent ground clearance, actually some of the best for long tubes. Also, you can buy them with AIR, and EGR fittings so that if you get a catted Y on there it would be emissions legal. Any good exhaust shop can fab you one up for about 2 bills. Theyre proven to make more RWHP except in forced in duction setups where it seems like shorties and mids are better ( They favor top end more, less torque down low ) So basically if your not going forced induction, there is no reason NOT to go with long tubes. More power, same effort to install, pretty much the same ground clearance with Pacesetters.

Most before/after dyno's with shorties show an increase of roughly 15 horsepower at the wheels. Long tubes generally show an increase of 20, sometimes even as high as 30 ( though rare ) more horsepower at the wheels. Not to mention a higher flatter tourque band all the way across, and it overall will show better area under the curve.

People dont switch from shorties to longtubes for no reason ... Hope this helps some

More power for your money, you won't be disappointed. My friend has shorties in his LT1 that puts about 400 to the wheels, and now whishes he should have gone with longtubes.

I think this is an area where you can,t go wrong getting LTs unless your lowering the car. LTs will make more power and if you do go badass with the engine you won,t have to spend the money again on headers. They do require a bit more thought in regards to the type of exhaust you run but I am running a set of fat hornies on mine and still don,t regret going with the LTs.

big time thanks for the responses, but i still have a little quetion. i live where there is no emissions can i get the pacesetter lt's without the emission crap. Also what all extra will i need to get the headers hooked up good. y-pipe? part numbers would help alot. longer O2 sensor wires, if so part number would help? thanks alot and keep the reasponses rolling in.

disagree. one of the rags did an article not too long ago that proved the shorties almost identicle to long tubes over the 3 to 6K range. heres the thread.

chevy high performance thread

havent seen the 20 to 30 dyno yet proving the longtube theory. peak maybe but not overall.

Lets dyno the best shorty, and the crappiest 1 5/8 (find one for an LT1.) long tube we can find.

Been beat to death. Next

what do you mean next?? the guy had a question take the time to answer it. if your so bored go to another thread. i thought i would give combustion some data which is way more than your reply did for him.

not everyone jumps on the long tube bandwagon. shorties and mids can provide a good alternative.

If for nothing else...get longtubes for the ease of changing spark plugs! That should be all of the convincing you need right there.

Agreed, agreed. But it irritates me when people post this (irrelevant) article over and over.

MAC mid lengths...PERIOD!

BTW, my 12.0 second car just went through MD. emissions 2 weeks ago...Try that with LTs.

Sorry...Can't "convince" you to make a BAD decision.

Well Let's not compare SLP SHORTIES TO MAC's!

I get my Mac's in tommorro and will hopefully install them over the weekend. I will let you all know gains.
