Nice sound
best bang for buck header for c5. only thing i don’t like is the slip on connections, if you don’t buy 3 inch camps or have it welded up it will leak! can’t beat the price though.
Way faster shipping than I expected. Showed up a few days earlier than predicted date. This was just my experience, yours may vary. The clamps, you have to tighten hard enough to pull the splines on the bolt through the block like lug studs.
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!
