Thumbs up Borla Headers and Stromung Hi-flow Cat

Recently installed Borla Headers (GenIV) and a Stromung Cat on my '00 RS and have to say they are a great combination. I was previously running stock with a Stromung Catback. The install was simple as the Cat is a drop in and everything bolted in to place with no problems at all.

She sounds incredible, unlike any other 4 cylinder out there. Actually resembles a Harley at WOT, thought deeper and not as sharp. When cruising on the hi-way the sound is quieter than just the catback, no droning. According to my butt dyno, definitely more power. She really pulls much stronger through the RPM range in every gear. The hesitation at 3500-4000 rpms is gone at WOT, and less noticable otherwise (I am also running a Cobb CAI and GFB Power Pulley Kit).

The biggest surprise is that over the past few fill-ups my gas mileage is running about 10% higher. typically average about 22-22.5 mpg (half hi-way in traffic and half stop & go getting there) since the install, been getting 24-25 mpg. Keep this up and it will pay for itself in about a decade or so. Have not had a chance for any extended road trips yet.

Did get a CEL, not a surprise. As for inspection, it will be very easy swapping out the Cat pipe. Should be able to keep everything else as is.

Last and definitely not least, picked up both pieces from Dale at Teague's Auto (www.teaguesauto.com). I can't say enough for Dale, he is incredibly knowledgable and won't steer you wrong. If you have not dealt with him yet, you should.

Forgot to mention. Pictures of the underside of my car after the install are on www.teaguesauto.com in the "Impreze RS/TS" section under exhaust.

Default So how did you....

deal with the midpipe? Where does the Stromung meet up at the end? Do you need the mid?

I have a Borla muffler; tried installing the MRT system, but the Austrailians got creative with their pipe bending and it wouldn't fit. Besides, they screwed up the bracket welding too.

Anyway, I've actually warmed up (very quickly) to the idea of finishing the Borla exhaust system (since I already have the muff from the previous owner) over trying to force the MRT one in.

Loving the fact the the headers are bolt on, along with the Stromung. But why the switch out for inspection for the cat? Stricter emissions in PA (vs NH, where I live)?

And also wondering if you modded the OEM mid, or found an SS pipe?

Thanks

Gator GT -- I have a Stromung SS Midpipe. The Catback was installed November 01, headers and cat this past May. The OEM mid should fit fine as each piece is designed to drop in.

As for emissions, not sure if the single cat will pass. I realize that getting the Cat nice and hot should help but considering i am due in January having stock cat ready to drop in is reassuring. As for emissions in PA, the Philly area sucks.

Installation was a snap, nothing had to be modified. Hope this helps

Mike&Michele,.

In refference to your comment of improve gas mileage, I can tell you that my car improved a whole lot with my entire Turbo back and Borla headers. I am making an average of 325-340miles per tank in town.

I agree with your comments about better gas mileage..

The combination Headers and catback is loud at WOT and there is some droning. Initially I thought of adding Dynamat to the trunk floor and both behind and below the rear seat but I have gotten used to it when cruising on the highway....so has my wife. We either enjoy the sounds of the engine or turn up the stereo a bit more. The engine typically wins.

I definitely do not regret the setup!
