Draw backs to LT

[CocaColaEatsPie]

I am planning on getting an LS1 F-body when I can afford it. I want to get a Borla exhaust. I'd also like to get a set of SLP long tube headers. What are the draw backs to long tube headers? There has to be some draw backs or everyone would have them. Why doesn't everyone have them? Why do you, or don't you have them???

Thanks,
Nick

Well first of all long tube headers are not street legal due to emissions. They move emissions equipment from their stock locations. The other drawback is they can be very loud. Many do not like their car to be loud.

As an aside - do some research - SLP headers are not regarded as the best for the LS1. They significantly decrease ground clearance - much more so than other brands.

exactly what casey said and if your gonna go with Long tubes go with the kooks or qtp's since they are stainless if you can afford them and if not just get the coasted pacesetters

then on the other hand if you have the stock exhaust manifolds and find that the factory stud bolts for the stock cats are snapping in half after only 3-4 years, you might think of getting LT's (me - the OEM stud bolts for the exhaust are rusting and corroding super-fast and snapping causing long-timed noise-vibrations)

Seriously, I have a hawk with the SLP bilstein option (some cars were ordered with this) and it drops the height of the car to the equivalent of lowering springs... I routinely scrape the bottom of my stock flat y-pipe when I go over speed-bumps, or bad bumps in the road. Once I get out my apt complex, headers will go on, as I only have plug-in obd-2 test

Think about your application and the benifits and trade offs before you commit (visual inspection, emissions-roller testing in some states, ground clearance, etc) .


Kooks seems to fit snug fyi

Actually, long tubes do not decrease ground clearance. The problem is with the aftermarket Y pipes.

The long tube's lowest point at the bottom of the collector is still higher than parts of the floorpan. It's the off the shelf Y pipes that have to negotiate the undercarriage and mate with the cat back that end up hitting speed bumps or banging the floorpan. I've seen great results with custom bent stuff. That's the way to go if you intend on long tubes and have satisfactory results.

OKay, so if I were to get the kooks, I would need the kooks long tubes with air fittings and egr weld on collectors, plus the 3 inch Y pipe with cats. And then the Borla goes from there?

I would also need the 24 inch O2 extentions, right? As well as the rear O2 sims?? Is that all right. I'll save for as long as I need to, to get what I want. I'm in high school and I work 40 horus a week so I usually make about $800 extra a month, after paying insurance and all my other expenses. Right now all that money is going into my account until I have about 9k so I can get the car, from there I'll save a few more months and do what I want to, to it.

With the exception of the SLP longtubes, most LS1 LT's are pretty tucked up close to the body of the car. Like Joe mentioned, the real ground clearance problem lies with the y-pipe. Kooks are excellent LT's...most likely the best available for the LSx right now. Kooks also tuck up very nicely.

I'll try to dig up some pics of various LT's on LSx's.
