Depends on whether you use cat's or not, but expect at least 30WHP if not more.

Arguably the most HP you can get reliably from any bolt on upgrade.

Thanks pdp180180, would this have more gain than SIKKY headers I think they're claiming 50 hp gain on they're website over stock... Sorry to hijack thread.

Unlikely.

Unless you start looking at more expensive designs from the likes of Novel, header designs are pretty similar. You'll notice PPE show different gains for cat-less installation versus hi-flow cat's.

The fully de-catted figures are 38-46 WHP, so pretty close to the 50 from Sikky's claims.

I'll be going with PPE unless I get a windfall from somewhere!

If I had the cash, would go for the Novel option.
