I finally bit the bullet and ordered a set of 1 3/4 stepped to 1 7/8's along with their catted y-pipe.
Once installed, i am wondering what I might be putting down to the ground....any thoughts???

ARHs are sweet. get the best and be done. thats how i see it.

 

Great headers for sure.

 

Yes, I am looking forward to receiving this product. I kept reading that ARH are the best, so I decided to do it once and right the first time. The car currently is running a set of JBA shorty headers (California), SLP y-pipe which I will probably be selling to someone who wants a little extra over stock performance, but lives in a state that is equally as strick as Calofornia. Its tough there, but it is what it is I guess.

 

Thank You for choosing ARH, we look forward to seeing the results.
