im looking for a down pipe to high flow cat kit i see some also with the u bend replacment but i had that done anyone no where i can find one also the car is not supercharged so it it worth it to do the down pipe and cat?

 

the car is a 01 ss n/a

 

from my understanding, you will see some HP gains... +/- 5?

 

most exhaust flow mods will hurt low end torque and help top end HP. also need to put the money where it is best. down pipe on a NA car isnt the best gain per dollar. new ported exhaust manifolds or ZZP's powerlogs should be your 2nd exhaust mod...right after removing the dreaded Ubend.

 

u bend is out as well as rez and flow 40's on the car with k and n cai and hyperteck max energy just thinking of what next

 

I doubt you'll feel any gain if you already have the ubend delete, and the engine is mostly stock.

I'd probably look into doing some 1.9:1 modded stock rockers. They pop up on cgp all the time under $250, and thats a mod you can actually feel.

After the Ubend, PEMS, and rockers I would go with a ported throttle body.
