    So I have heard that CRS? has come out with a set of 4 into 1 headers to suit 2nd gen LS engine swaps.  Anyone have any details on them.   A link would be great.

    But also has anyone got them on their car?  Very interested in how well they fit, particularly around the steering column?

    Just the collector need to be tapered

    Cheers Cav, I couldn’t for the life of me find the link here on the home PC.  So Pete do you think 1 7/8 primaries are the go, originally i was thinking 2″ but tbh I am not sure I could fit them in with mine?  Reading how yours have performed have got me looking at these..

    Has anyone out there got them actually on a car?

    One thing I didn’t mention to anyone about my pipes was I left two gouges in my drive way when I left and now have had to lift it 25mm to get enough clearance

     

     

    Gary 2 inch for 454 would be my personal decision, would probley get some one to use that programs pirate used on my thread on about page 3 that showed the 2 step designers lengths and all the harmonic lengths

     

     

    Something like 6 inches then step from 1 7/8 to 2 inch

     

     

    That’s if you have a spare 5 days to make them

    And they are $1500, which if they fit well I reckon is good, but its lot of money to spend if they dont fit well, or hang too low.  Really like to find someone who has them and get some pics of how they are arouund the steering and how low they sit.

    Thanks Pete, you must have been posting as I was, yea just not sure.  I am not going to build my own, I think thats just too much for my skills, a man has to know his limitations.  Its really either leave them as is until the time comes to do a package of upgrades and go full custom or if I can find someone who has used these and I am confident they fit, fitting them and modifying my exhaust to suit I can manage.

    I found a few photos of these being used in a VN.  If you want to get in contact with the guy running them it’s in the Facebook group https://m.facebook.com/groups/531793363539450

    In a convo about using a cvr starter in original spot and running custom pipes.

    they look right. Having a manual rack will help. Would love to see ground clearance tho.

    Just looking at them, doesn’t look like they are sitting lower than the bottom of the trans pan (not the best angle photo though)
