Default Brullen vs. Borla vs ?

This has been debated several times in other forums, but I wanted to get your inputs on the advantages of one vs. the other on a Legacy. I'm looking for a full manifold back system. It seems that you get more with the Brullen but other there other quantitative/qualitative measures as well? Both are SS and tough as heck. How would you set up your car from the heads back? And does the Brullen equal-length header really diminish/eliminate that fabulous Boxer sound that we all love?

Looking to put this on a regular 98 BD (DOHC) 5 speed
Thanks in advance folks

Br, Dale

Well, I think that what has been said about the varying exhausts for the impreza generally will hold true for the Legacy. Aside from the Brullen & Borla you mentioned, there is also the Stromung, MRT, Scoobysport (I think) and a home brewed model from your midas shop. I can't remember now, but there were a few fitment issues for some of the Legacy exhausts, but past that, it seems mainly you end up just comparing price/warranty/look/sound and customer service from the vendor. I believe that the power gains are roughly the same throughout each brand.

As for the wonderful boxer sound, IMHO, I think the header-back systems actually enhance the boxer sound, again varying between brand/flavor.

Hope that helps somewhat,

Subietonic - The best way to help you decide is do a spreadsheet w/ certain criteria you'd like to have. Then check it off like a check list.

I can tell you now that the Borla header + Random Tech cat + Borla Cat-back will run in price very similar to the iON/Brullen set-up. However, this would not necessarily be the ideal set-up for you as the header is un-equal length, as well, you can't choose your own acoustic preferences (which it maybe ending up being too loud for your tastes).

Crazy Ken installed his iON/Brullen set-up w/ the medium acoustic cat-back, and he loves it.

As for the power issue, the iON/Brullen, SYMS as well as MRT systems are the only fully matched systems. (ie: manifold + cat-back portion are made for each other specifically to maximize flow). The SYMS and iON/Brullen set-up should provide more power than a straight MRT header-back system (this is due to the shaper bends, pipe diameter, choice of cat used, restrictive rear muffler section).

In regards to the sound issue, you won't loose that distinctive boxer sound, however it will be rounded out and smoothend with an equal length set-up.
