I installed the kit today and everything kit as it should. The headers went on in about 1.5 hours installation was easy. It needed no alterations.
X-Pipe kit took about 2.5 hours. It was a little frustrating because I did this entire install with a floor jack and jack stands.
Over-all the kit was great for the price and it sounds good. Today I ordered the tru-dual kit. I wish I would have purchased it with the kit because I would still like it louder (not my daily).
I have been running this set of headers along with the complete Speed engineering exhaust system for 2 years and counting on my C6 and I absolutely love them. Even on track days I have people surrounding my car asking me what I did to make this car sound so good and I always point them over to speed engineering. These headers also fit better and give the most clearance I have seen from any of the aftermarket companies. Thank you, Speed Engineering!
I purchased these for my 05 C6 LS2 and I will just say it was worth it, never had an install so easy in my life. I have a T56 only thing to watch out for is the clutch cable on the driver side, these cleared everything and fit in very well, bolted up nice. I had to trim my dipstick bracket a hair for it to bolt back in properly, no big deal. you will want to get different plug wires then the AC Delcos that are OEM because the boot will touch the #2 primary tube, so if you're reading this take that into consideration. finish was great, however Fed Ex was not gentle with the hadling of my parts, they still weren't dented or scratched up. 10/10 I would recommend and if I buy another Vette, this is the first place im coming!
After hearing the horror stories of ebay longtubes and x pipe, a friend of mine recommended i purchase these speed engineering longtube headers and x pipe. The install went incredibly well, im unsure why anyone would purchase kooks or any other headers besides these. no modification needed whatsoever!! bolt in and bolt out. i was able to install mine with the factory plug wires and without o2 extensions. the quality is good and they sound amazing. Only issue is the clamps leak a LITTLE bit. i still run them however. 10/10 would purchase again.
