Just thought I'd share.. I didn't take a before pic (I'm a dumbass) but here's the after..
The first bank has tubular headers.. so from the factory the exhaust flows pretty well, but the second bank has manifolds.. they were very restrictive and had a very rough finish with slag/etc..
It is a v6 at least so I fit in more on the board
but they're for my regal
The butt dyno didn't feel too much, helped out top end definitely.. and boost stacking already dropped about 1.5 PSI.. (With the CAI the car was pushing about 9.5 when its rated at ~7.5... because of backups in the exhaust..) once I get my 3" downpipe on I'll be even better off... can't wait lol
then I only have to do colder plugs, tstat and I'm set to upgrade my pulley... insta 13s, woot!
