I'm running the HKS downpipe, WORKS high-flow cat, and 30th annversary cat-back. It all fits great and no leaks!

Evo348

does the 30th ann hi power bring all bolts and things for a complete installation cuz i dont think the stock ones will go back on after you remove them. Also can you list any websites that has this exhaust for a good price?? thanks for the replies. Im thinking of getting this exhaust with the AMS high flow cat and what downpipe do u recommend?

The HKS cat-back system will come with everything you need for it to bolt to the stock cat. If you're upgrading to a high-flow cat at the same time, make sure the AMS cat comes w/ everything you need for it to replace the stocker.

well on their site it says " The AMS EVO VIII high flow cat is designed to bolt up to our stainless steel 3" downpipe and catback exhaust system. " so im not really that sure if it will fit the hi power exhaust what do u think? And im not really sure if the AMS downpipe will retain teh stock lower tie bars. This is very important. I know the buschur does yet it will only fit THEIR highflow and catback since everything is held together by clamps and this is what i dont liek about it.

From the pictures I've seen of the AMS exhaust parts, it looks like their parts are not designed to work with stock parts. So I don't think the AMS high-flow cat will work with the HKS cat-back. Why not get a Helix or WORKS high-flow cat? Both of them are designed to work in the place of a stock cat.

Which oen do u recommend from those two brands?? do u have any links where they sell them? I wanna get the hks hi power though, what should i do? Cuz the problem is i have to get somethings that will fit the hks and the ams.

The Helix will give you more power, but will make your car louder. It is also very flashy and doesn't look like a cat if a cop looks under your car.

The WORKS cat looks like a normal cat, flows better than stock, but is not much louder. I have the WORKS cat. I like it. Check it out at www.worksevo.com.

im going for more power. The hell with the cops and if they dotn think its a cat thats their problem. Now what 3" downpipe should i get? i know the helix or works will fit the hi power, so all i need is a downpipe that will fit the cat....whats your set up and where did you get ur partS? Also i need the downpipe to fit the stock lower tie bars.

Either downpipe will work w/ the hi-powerw cat-back. You can't go wrong either way.

I have HKS downpipe and WORKS HFC.

Buschur Dp will NOT work with HKS 30th exhaust. I dont know why these people here that posted before me didnt tell u that

Evo348

yea i kinda figured that about the BR downpipe. What i dont like about the hks downpipe is that its not 3", so im looking for a 3" downpipe that will fit the works high flow and hks hi power catback. Damn this is so difficult

I have the full HKS exhaust. The downpipe measures 2 1/2"ID and the catback measures 2 3/4"ID except were it meets the cat were its 2 1/2" ID.

Evo348

so helix or works downpipe, helix or works high flow, and hks hi power and problem solved??
