Default LG vs Kooks

I'm really thinking about adding headers and x pipe to my 2000 vert. I have Corsa Pace car mufflers now. What are the differences between LG longtubes and the Kooks setup? The cost difference is pretty big with the Kooks being alot more. Any thoughts would be appreciated.

i dont really know the diff. between the two besides the price. but i just installed lg streets and have the corsa pace car also, and it sounds great. im kinda partial but i would go with LG, because the are cheaper and sound great.

They are about the same price as the LG Pros, which is what I have and love them.

I have Lg and cant be happier. Ive had them for 2 years now and nothing but great sound and extra power. But either way i think you will be happy with your purchase.

I've watched many Dyno runs with different LT's and pretty much they all perform the same when it comes down to it.

save the extra $$ and get the ones that cost less and add something else to the Vette with the savings! You'll be glad you did

For the record I do run KOOKS 1 3/4" Headers Hiflow Cats and X-PIPE!

Thanks,Matt

From my research, Kooks will make more power on top end and LGs will make more torque on low to mid range.

Thanks guys. I think the answer is clear. One more question. What's the difference between Lg Pro and the street series?

The shorter primaries of the Kooks will perform better at higher RPMs than the shorter primaries of the LGs. For some reason people like more power down low where its not usable. I run Kooks. However the performance difference is pretty minimal. For a car that doesn't frequent the track I'd say it doesn't really matter much.

They both have the same primaries, the pros have a 3" true x-pipe where as the streets have a stamped 2.5" x-pipe.

some people do more than drag race and when you're coming out of a tight corner at lower RPMs you need that low end torque.

that said, i would go with the cheaper ones because there isn't enough difference between them for it to matter on a street car.

if you have any interest in acceleration why would you be coming out of a corner at lower RPMs? next time try downshifing.

Kooks here, I like the setup and I'm happy with the results. I was also considering Dynatechs and LG's. I didn't know about American Racing Headers until later. All excellent products though!

you have to if you don't have any low end torque, of course you lose time with every shift so sometimes it's quicker to let things drop down to around 3K RPM than to downshift, then shift back 2 seconds later. That's like the 4.10 gears, yeah you accelerate faster, but you spend so much time shifting that your lap times aren't any faster, not to mention the extra heat in the trans & diff.

My point being that for anything other than drag racing, it's better to have a nice, broad, usable torque curve and than just peak power
