When i bought my ARH longtubes i asked a few tuners about the differences between 13/4 and 1 7/8 and one (JDM) swore to me me that everytime you have have a car under 800 rwhp they were seeing the 1 3/4 perform better as the bigger tubes were giving some power down low.
I know some have said the opposite but thats what they told me..
I honestly think either sizes are good and anybody should be happy with these.
I was certainly happy with my ARH 1 3/4 but switched to the Kooks superstreet to comply more easily with the new regulations in effect in my area.
what brand do u recomend?i hear good things bout the kooks but they are pricey for a street car.beefcake racing got any used?i will be at bowling green.

My final results stock exhaust manifold with UPR ORX pipe vs BBK 1 3/4" LT headers with ORX pipe. Pretty nice gain all the way through.
So you gained 9hp and 9ft/lbs TQ overall going from OR-X to LT's but the midrange looks markedly improved.

The LT headers at 3k have almost 50 rwtq more and 20+ rwhp and you definitely feel that when driving the car around. The headers I feel were worth installing. Prices on installation varied greatly from $1,150 to $500. I sat and watched the install and with the tech working at a moderate pace it took just under 5 hours.
What I appreciate most about the post is the comparison between an off-road pipe vs headers. I would do the install myself.
I really appreciate your post. Thanks.
