jba longtubes

emission testing aside, would you get them? theyre half the price of thorleys.

been researching and came across a few that had exhaust leaks at the header flange and they figured it was warped. Now is this because they didnt use the proper gasket that urd supplies? or is this crappy workmanship?

im hooked on the longtubes for the added growl, ease of install, and i have nothing for emission testing here.

 

X2 i would like to know as well

One of my friends runs them on his X and they seem to hold up fine although he is using the "hardcore" gaskets from urd. http://www.urdusa.com/Exhaust-&-Hea...Throley-1GR-headers/Y-Pipes/product_info.html
I also run this gasket on my DTLT and stock y and I don't have any leak issues.

 

I have them, and i really like them. Except they are not a perfect fit to the y-pipe, so i have developed leaking issues. I am switching to v-band flanges soon.

I took my truck out and did 0-60 runs with my truck before and after the headers were installed.

7.2 was my best time before install
6.8 was my best time after install

Same passenger, same amount of fuel in the tank. I'm sure this number is a little exaggerated involving human error (passenger timed me), but it is obvious that i got at least some performance increase.

Believe me if you want. I'm just sharing my experience.

FWIW. I didn't notice a drop in low end (First thing i was worried about). very possible that it is in my head though.

 

Hmm maybe i will give a set of these gaskets a try first.

 

Thanks for the feed back I will research those gaskets. Not overly concerned with the low end power "myth" I doubt I'll really notice it since I'm planning on getting 33's soon, then maybe a regear.

 

Headers only help in the higher rpms and are quite useless on the street. Sure they sound cool and all that but the dyno doesn't lie. Most street engines rely on buily in back pressure in the exhaust system for low end torque.

Myth... eh. Yea now that's funny right there.

 

im not really too concerned over it. but it says those gaskets are for the DT headers, im assuming they still work with jbas
