Kooks 1 7/8 headers installed
Got my Kooks 1 7/8 headers w/ 3"x3" crossover w/ hi-flow cats installed. I have a friend that works for Chevy who put them on. He said they were a real mother f#@*!%. Vette sounds nice and pulls really hard. If anybody needs some pointers on install just ask. My friend told me what he had to do.

Re: Kooks 1 7/8 headers installed (LittleBoyBlu99)
If I remember correctly, you were previously running 1 3/4" longtubes on your stroker and then changed to the 1 7/8" Kooks. (?)
If this is the case, then I'd be interested in finding out if you noticed either a drop on the low end or if you opened up the top end with the exhaust change.
Please share your experience...either with a dyno pull or by a "seat of the pants" description. There are lots of us on the forum (I for one) just waiting to get some input on the Kooks. sj

Re: Kooks 1 7/8 headers installed (88sk)
Haven't re-dyno'd since the 1 7/8" Kooks install but they did produce a SOTP difference in all RPM ranges, most notably above 5500 RPM. They also produced a deeper sound at idle and cruise, louder at WOT.
BTW, had TPIS 1 3/4", no cats, and Bassani x-pipe (nice set-up) and now have Kooks 1 7/8", random tech MM cats, and 3" pipes back to catback. Last dyno was 504RWHP -500RWT -

Re: Kooks 1 7/8 headers installed (88sk)
can these be put on from underneath so dont have to remove stuff from the top??
remove starter, oil filter and cradle nuts. Dis-connect the steering rod and then raise the engine, one side at a time (the side you are installing)

Re: Kooks 1 7/8 headers installed ('97 C5)
Do you really have to take off the starter and the oil filter? What a son of a bitch! Plan on takling mine next weekend, how long did it take you guys to install?

We installed these on our 427 Z06. We had been originally running SW 1 3/4" hedaers. Here is a link with the graph: http://www.ls1speed.com/z06.cfm
