Hi guys just wonedring how long it would take to install a cat back. Only ask becasue I'm trying to set-up some dyno time with ATP, since I cann't go on the 6th, to get some numbers on the new Borla hush system. THey just asked me how long it would take to install the catback, since I want to do back to back runs. Also by doing back to back runs to you think I would get good numbers? I mean does it not take some time for the ECU to learn that there is more flow now? I was thinking of doing back to back runs and then getting it dynoed a month or so later. What do you guys think.


thanks,

Jason

 

Installing a catback takes about 15-20 min. Maybe up to 30-50 min if you're doing it yourself.

 

A cat back install is fairly easy; about 30min. tops. One trick is to use WD40 on the exhaust hangers. this makes it much easier to get them off and then on again. Also the higher up in the air the car is the easier on your back it will be.

 

how much are you gonna get the Borla hush for and where?

 

If you have my luck (all bad) it takes 1.5 hours.

I'm getting the borla hush from MPJ oh and Preston did ya wanna come down with me when I get the dyno runs set-up, i could use some help changing out the muffler. A bit off topic but i dropped off my sideskirts today at creative kustoms, and it should be done by friday.

PM me w/ the details of when you're getting your dyno runs.

 

It's pretty straightforward. I got help only in the form of someone handing me the tools while I juggled the pipe underneath the car. The worst part was hooking it up with the Kartboy hangers, but it wasn't too bad (the factory hangers are really mushy soft rubber and stretch).

with ramps and wd-40 30minutes top. without... maybe 50+

Very easy to do. you won't have any problems

 

BTW my Borla Hush is in the mail via MPJ too.

 

Two bolts, 4 hangars... 1 hour if youve never done it before, 30 minutes if you know what you are doing, 10 minutes if you have a team

 

I'm working on getting a team. I'm picking up my exhaust tommorrow and I plan on practicing at home so I can do it as quickly as possible, since the email I just got from ATP said that for a half hour it gonna cost me $85 for 3 runs and an hour is gonna cost me $125. I'm gonna go for the hour of dyno time, unless you guys can recommend another dyno place.

I'd save your money/time and just get the final product dyno'd. ATP should know roughly what a stock wrx makes on their dyno.

A catback doesn't really do much with an otherwise stock exhaust system, 5-10hp. And you said it yourself that the ECU won't learn anyway (unless you do the "Vishnu Reset" in between).

Good luck!

 

I know that is what I should do, but it might be a while until I have my car the way I want it, so I figure why not dyno it now, just to see if there is any immediate change in power/torque output. Besides I know different stock cars vary, if slightly, in the amount of power they put down and I think being the curious guy I am I would like to see what my car puts down stock, although if I wasn't so obsessive compulsive I would just go by what other stock WRXs have been putting down. I think a month and a half from now I'll just do a 30 min dyno session to see if there is any more improvement from the ecu learning.

I forget what the size of the bolts are (i think 14mm but don't quote me)

-you'll need 2 high ramps
-a water bottle (to cool the exhaust quicker)
- two sets of gloves
-a bottle of break free or wd-40
-two same size box wrenches (14mm?)
-two (14mm?) ratchet wrenches with semi-deep sockets
-and an extra guy...

you'll have it switched out in 10 minutes flat.
