The install was very simple for the headers, they fit perfectly as well. Only issue is the passenger side was barely touching the transmission cooler line, which was remedied with some heat wrap. The fact that these are 1/4 the price of other brands, these are so worth it.
MAKE SURE YOU READ! I ordered the headers without the X-Pipe kit thinking it would connect to the stock midpipe. It does not… That was due to my lack of reading before ordering. Other than that, no issues. Ordered from Speed Engineering for my C5, now my C6, and never had any issues!
Headers fit good , The X pipe kit was a little loose but with a little modification fit snug
Would definitely recommend buying
Put them on my c6 ls3 about a month or so ago, the only hard part is the there’s no instructions so my buddy has the x pipe backwards for the better part of an hour or two but otherwise fit like a glove but I did have a rattle sound till we tightened the bolts too, sounds amazing going into my npp exhaust, only downside is that since the walls/headers are thinner than other brands you can hear ticking from the engine which is normal and to be expected solid 8/10 gonna try a pair for my Mustang gt 5.0
Just installed headers and x-pipe on a 2005 ls2 Corvette. I have put on a lot of headers on cars over the years but these were the best fitting ones yet. Real happy.
Fitment on these are top notch, they’re nice and tight against the underside of the car, they don’t hang low like other manufacturers, welds are very nice as well and are welded on the inside of the head flange too. Top quality at a unbeatable price
