kooks is specific for the added length length of the caprice

other wise the others work with a bit of stretching , some systems have a little extra length when they slip together

ive got the 2" arh system for mine , but waiting to collect the sc parts i need before installing them
Poor wording on my part; I meant to say, "I doubt you will find them listed for the Caprice [by ARH]..."

2" primaries? Oh my.

s/c'd cav, that's a good goal, 800, from an L77? If you have time, please outline your modifications, it's educational to see other peoples mechanical creations.

I saw a Caprice PPV on Craigslist ( sold when I contacted him ) that listed Pacesetter long tube headers as one of the modifications, just thought I would add that vendor to the list already mentioned.

Thanks s/c'd cav,
So any headers that are specific to the Chevy SS will clear the oil cooler? Is that slow true for the length needed to pair up with stock exhaust system on a Caprice PPV?

Thank you again for your replies to posts!

Is there any reason why the Doug Thorley headers would not fit a WN series Caprice? There website stops short of 2014 on application and when I called, they could not guarantee the application.

Thanks!
