i think he's talking about the NA full dual exhaust that mazdatrix sells.



They come in two versions...

version 1 uses HKS mufflers

version 2 uses RB mufflers



personally i hve never found anything bad with HKS... they make better stuff then apex-i and trust but thats my opinion. THen again have never seen a BAD Racing Beat Product... except for their engine torque brace for FCs, and a blown SS RB oil cooler line

i had the hks sport catback on my t2 and it fit better and was less restrictive than the n1 single. the racing beat i has was the full turbo back so its kind of a tomato/tomato debate

My experience with HKS exhaust is that the fitment wasn't a nice as TRUST...and I am a loyal RB kinda guy...HKS has my vote for turbos and electronics though...just cant afford them,lol.
