Ivan,
If Im reading right, you saw 10rwhp increase, but at top of the RPM curve; and only 6ft lbs in TQ? Interesting that no visible increase in lower RPM ranges--despite seat of the pants impressions.
Already have HF Cats and cat-back system, so searching for headers I can marry up to stock fitments. Any other great options out there other than DT Shorties?
Thoughts?

They weigh CONSIDERBLY less that the factories... that for sure. Exact number i don't have. However, I put these on my car almost 10 months ago now... i DID have a small issue on the drivers side connection to the collector. But that was fixed with a little bit of heat on the down pipe =o). Ive had them on there like i said close to a year now and everything is great. I can't really speak to the increase in exhaust note, as i put the full cat back exhaust on at the same time... I know it's sounds ridiculous right now with the factory cat and resonators in there and just the magnaflow straight pipes to 5" tips (Cam helps it to i guess).

I would say though... if your looking for a in expensive upgrade as far as headers are concerned... this route is a good idea.. I hope you guys have a lift... it don't know how I would of done it without mine.

Well I had my Doug thorleys installed last week, the sounds was a little deeper with GMMP exhaust, but wish I would have gone with long tubes. Im content for now...........

can u install these with putting the car on jack stands?? i want to do the install myself.

wrbear · 03-06-2011, 08:13 PM

I installed these myself....some thoughts......you can install them (both) from the top, you will have to loosen some things on the passenger side though.......you do need jack stands to raise the cats to make the connection (they will drop a few inches)....you can use the factory gaskets....well I did with 500 miles on the car.....18 ft/lb's torque...use some red loctite to lock the bolts in place. They will void your exhaust warranty but I'm sure most are adding cat-backs etc.
