When I added my JBA headers, I had the Stillen bpipes added which were 2.5" and then had it connected to the Banks y pipe....And I'm getting it put on this week. I'm stoked! I have been reading that you shoud neck down the y-pipe to a 2 1/2" pipe to keep some of your bottom end power. Has anyone actually done this with the Banks exhaust? Do you think it helped? Thanks!
DIBS!!:teethmast:teethmastI have the banks exhaust. I noticed alot of low end tq loss. I own it up to heavy tires and 2.94 gears but the 2" to 3" difference from b pipes to exhaust didn't help either. Now I have my stock y pipe into a flowmaster collector ran to the banks muffler and dumped it before the axle. I gained back my tq and lost all the drone the banks has during acceleration. Soon ill be changing mufflers and selling the banks exhaust.
