I cut my cat out in front of the stock silencer and had a pipe welded in. Car isn't any louder than stock. Really cheap and I wish I had done this in combo with the RB race flash before I went FI.

 

How do you like the race flash? I have street flash with midpipe and it pulls pretty good up top say from 5000 rpm and up. Does the race flash pull better down low? If so is it something that you definitely can feel while driving? I am just curious. I tried to ask this question but noone seem to answer it. I would imagine that the map would be similar between the two after 5K rpm but different from 3-5K rpm for race flash.

 

i dont have a welder, and there is no way a shop would do it for me, that is a $10,000 fine. but i am wondering the same question as Ron.

 

I would buy a resonated midpipe - in combination with the stock catback, it will be relatively quiet, yet loud at WOT.

Come emissions time, just bolt the old cat back in, 1 hour, tops.

Any aftermarket silencer is going to be a ticket magnet with no cat, I have a Borla and even it gets raucous at moderate throttle inputs.

To answer the other question, I find the race flash definitely pulls stronger in the midrange, but have not compared it to the street version.

You work for the largest motorcycle mfg in the world and can't get a little "G" welding job done?

Your best bet is to listen to Stealth

 

alright, thanks for the info, and if all goes well, i will try to post a sound clip. If it sounds good, i wont even buy a cat back then, just save 600-800 for a different thing. maybe nitrous.

 

Phil, we dont do any welding here, its all assembly and CNC'ing. Otherwise i would give it a try, i could probably get the piping for free too. oh well, mid/resonator, here i come! wait, what about a CEL? i thought the midpipe will throw one.

 

Oh well, so much for custom bikes from the factory. I guess I just remember the old days when they were built to order (kinda dates me i guess). I'm not sure about all mid pipes throwing a cel as I use an supercat with my RB catback and do not get a cel from that (I get one from the X) and the sound is very reasonable. The supercat is modified by standards set in the DIY threads and the noise does not turn heads except when I get in the boost. I read pros & cons on the RB flash. Why not save the money and try the Cobb flash for the N/A 8s that should be coming out in the first quarter of the new year?

 

well the supercat supposedly melts if you get the race reflash. What cobb flash? i never heard of it.

 

cobb? http://www.cobbtuning.com/
my buddy has a 07 wrx, they claim that with the cobb ECU and the recommended exhaust, his car could pull up about 30 hp and 43 lb-ft torque, obviously it is crank power.
the other interesting things is that the new turbo my buddy is thinking to get, he doesnt need to get it tuned. because the ECU access port made by cobb, has many different types of maps, which fit different type of driving condition you want, and the map for that turbo actually has been made in the port.
isnt it sweet???but obviously wrx is originally made as a turbocharged car, it is so much easier to get some power than N/A cars.
i dont know what they can make for the 8s

 

Cobb's Access Port is nothing new to us... its been on the board for quite some time.. they've been able to actually flash our ECU's successfully for quite some time(just ask Team) but they havent yet got it all into a package to be distributed or some nonsense. you can find discussion about the access port in the AFSC thread as well as other places

 

Reading my original post I can understand how it would be misunderstood. I never had the RB reflash. What I meant was that I wish I had done that mod w/ my exhaust mod while waiting to go F/I.

I also should have caveated that w/ this mod is a no go for those that live in "sniffer" states.

 

haha, we only build the engines here. the bike assembly plants are york pensylvania and kansas city missouri. if you want a custom bike from the factory, check this out: http://www.harley-davidson.com/wcm/C...&nickname=Chet

go to softail, and then the rocker or rocker c, those are badass. but back on topic, i know about the cobb EMU, but i didnt know they have a reflash, and you guys are saying its better than the RB reflash?

 

bump

 

Update - Always ran premium (91 here) for first two years of ownership, then tried Regular (87) with great results - no ping and at least the same, possibly more power.

After the Flash, I returned to Premium, due to the new tuning, but as it is now mid-winter, temps around 0*f and driving in icy commuter traffic, I figured I could slip back to Regular for a while.

No way. Any excursions into the higher revs (8k+) gets the flashing CEL,and any large throttle openings below 2.5k, causes the ping-pong ball noise!!

My test is more-than-complete, nothing less than Premium with this Flash!

Cobb's init is not a messy piggyback liek the INT-X, it reflashes your PCM for you. If you or a tuner you trust get the tuning software, you can flash a custom map for your specific car, exactly how it's set up.

 

its weird to read my old posts and see how inexperienced i was. well i have heard a lot of opinions about both the flashes, and from what i read from keef, i am going to go with the "race" flash

 

Does the RB reflash conflict if going FI and using the Int-X?

 

Nope - just renders it useless.

Int-X is a standalone for fuel.

 

ive had the race flash for some time now and has to be the second best mod ive had... from what i understand (for the people who keep asking) the race flash raises the egts so high that even a high temp cat will not survive....
i have a aftermarket 3" cat that has been gutted with 3" pipe through a custom resonator all the way to my mazdaspeed exhaust (old version). i havent dyno'd it yet but after messing with my exhaust about 8 times this seems to work best. being quiet and performing well.... and it also shoots flames

 

So you bought an aftermarket cat abd gutted it?

What a waste.

 

yea i bought it first ... then got the reflash and realized i had to gut it. also if copers look down there they will see a cat!

 

BUMP, though this topic may be searched for less (primarily due to Cobb), I thought it was still a valuable contribution to the thread...

Around January I was toying with purchasing the racing beat flash. I emailed a few questions and this is part of the response I got back:

Just thought it was some useful info, some contradicting what StealthTL stated ::
