Best Quality High Flow Cat, And JDM Rear Bumper
 

Does anyone here know where I can get a HIGH quality stainless High Flow Cat for my 06' IX MR. I'm also looking for the JDM rear bumper with the black diffuser (sick looking). I want both things asap. I would love to hear suggestions on which High Flow Cat is best (Preferably Japanese) sound wise, flow, and performance. I have a Blitz TBE, Stock CAT, and a Fujitsubo RM01A Cat Back, to let you know for fitment. Again my car is the '06 EVO IX MR. {thumbup}

Any suggestions? ( crickets ):confused:

I would try Random Technologies. They make completely integrated cats into down pipes also.

i have an Ultimate Racing cat. Its pretty decent for its price, however it still has restriction over a testpipe...

From what i read Randomtech is probably the best deal, but it is pretty costly, around 330 usd...

You could even look at Mine's or Sard but we are talking Mega Money... over 500 dollars...

i prefer to use the UR HFC and a testpipe for the track...

I'm lookin right now.

Is an Invidia Test Pipe gonna be a huge difference over a RandomTech High Flo Cat? I know soundwise it will be but is the performance difference dramatic? I'm really undecided.

And what about the JDM rear bumper for my IX. That's #2 on my list. Who has them?

I think Gruppe-S carries them.

Call up Cal @ Speed Element 510-226-8822 I got my JDM rear bumper from them last week. Great shop!

Gruppe-S charges $899 with free shipping to lower 48 states. Btw, this is my 500th post. I'm proud to make this post and make a note of it since I've been waiting for this moment for 4 years. I'm officially an "evolved member". I've ready many stories dating back to the 03 evos when they first came out. A special Thank You goes out to everyone on EvoM including the moderators. Back on topic, Gruppe-S has great reputation and sells genuine JDM bumpers at a decent price.

Works also has a "stealth" high flow cat....not sure what the price is...give them a look

Thank's 4 all the quick info, what about the power difference between a Test Pipe ( Invidia ) vs. High Flo CAT ( Undecided Brand ). Is the power difference of a Test Pipe worth the noise and is it a dramatic performance difference vs. a High Flo CAT ? I'm having a tough time making the decision, I need input. I wanna know from both sides ( People with Test Pipes, and People with High Flo Cat's ) Advantages/Disadvantages/Gains. And Congrats on the 500th post by the way. {thumbup}

Check out ultrarev.com for the Random Tech HFC. I think they are around $265, and they offer a 5% discount to EvoM members. The Random Tech HFC has no O2 sensor bung like the stock cat. If your catback piece does not have an O2 sensor bung, you'll have to get one welded into the Random Tech HFC. I've got the Random Tech HFC on my car with an otherwise stock exhaust. Installed it at the same time I did an AMS LICP. I wish I had dynoed it just to see what it did if anything.

I would just get a high flow cat and gut the inside out. Now you got flow as a test pipe.

im in the market for theses puppies too..

You mean somthing like this?? Road Race Engineering "rally cat"
