Sorry for the Mega-delay! The KOOKS 1 7/8" LT's without cats make 30 RWHP and 35 RWTQ and with cats we've seen an average of 25-28 RWHP and 32-34 RWTQ. The cats honestly don't affect the performance that much and we recommend using them. We also recommend using new GM header gaskets as well. These number are without tuning as well.


Everyone's emails and PM's have been replied to! Thanks everyone for all the support! Feel free to call, email or PM us with any questions, or for pricing on our Kooks systems! Have a great day!

Kind regards,

Alec
