modz · 02-09-2010, 12:28 PM

Hey guys saw these headers in HPF:

Do you think it's worth putting these in?

Factoring the price, getting pulled over for noise pollution?

perfectg · 02-09-2010, 04:11 PM

do it

noise pollution? shouldnt be more than aftermarket exhaust, specially if u are still running cats

Talked to Chris from HPF, they said it is not in mass production yet , MXP is still looking to test fit the headers first.

biggest problem with headers for inline 6 engines is losing some torque when installing headers without repositioning the cats a bit further towards the back

Headers show about 15WHP gain.
Dyno proven with primary cats removed. You'll notice alot more noise though.
I'll wait till some ebay headers come out. The MXP ones look like they're from china.
