since i got my test pipes it has just stunk. like an old corvette. is this normal or would an ecu reflash help this? it smells like my friends 67 stingray...

 

normal.

 

it stanks!!! asphixiating!!! im geting them off asap.

 

lol, look into high flow cats

 

The trick is to not sit too long in 1 spot and never backup with the windows down.

 

Hold your breath while backing out of your garage

 

That's good to know, I didn't realize they smelled bad. Also other than the fact of doing air/fuel ratios with them do they increase HP?

 

yes

 

shoulda done some research on "test pipe smells" before purchase! hahaha. My crawford HFC's smell a little bit, not as bad as you describe though, perhaps you should consider some of these. They lose about 2-3 ponies over the test pipes but you wont have to hear the annoying rasp.

 

my test pipes do NOT rasp with my injen ti exhaust. ZERO rasp. just clean engine noise. incredible. but stanky

 

if you dont want em ill take them off your hands...
