How about offer the same 304ss for your intakes?

Maybe a couple different package deals. Intake + downpipes.

You don't want 304ss intakes dude. Once you see these carbon fiber intakes in person, you'll want to tuck them under your pillow and sleep with them. You're wife will get jealous

Oh I know I don't bud! Lol.
It's just another economical option for people that don't want to spend 1500-1800.

Dammit!

It's all good get us some dyno numbers.
I'll probably have these installed at the same dyno shop I've been using, and then do some runs.

The $1000 price is intro price though I think.

I hope the wastegate rattling won't be too bad

^^^ rattle is car dependant not DP dependant.

Glad to see a 'cheaper' option for down pipes- the 'others' are just milking it.

Good to see pipes without a bunch of welded pieces put together.

The mandrel bends look good, but remember that most downpipes have larger inlet pipe diameter and taper down to the outlet that connects to the mid-pipe. So essentially unless these are larger diameter than stock, you're losing exhaust flow.

That is true to a degree, but the gain is from the removal of the catalytic converter. The downpipes flare from 3.25 to 3.00. We did our flaring in the flange and created velocity stack. The choke point would be 4-5 inches further down. That is almost negligible when it comes to the volume of flow moving. The downpipes step down one more time where they meet the OEM pieces. So in reality that is the choke point, everything prior to that really doesn't matter because nobody can increase that area without reproducing all the exhaust after the downpipe.
