exact...i got rid of the bottleneck sections on my borla system,and put an x-pipe in place of the resonator...what a difference

So I have to ask, which X pipe did you use and how much did the resonance increase?. Also are you running headers?

The straight pipes are pretty quiet. But I do notice at about 2000rpm's the little round plunger you have to pull up on to put it in reverse buzzes. But it always buzzes. A little lithium grease should take care of that.

Tighten the set screw.

"Splain, Lucy!" "What a difference"... in what way, zackly?

(Also considering an X pipe fm SW = my reason for asking.)

ill try to explain what i did-pardon my english-apart from the bottleneck section close to the resonator,early borla systems have a sort of ring inside the pipe,about 4-5 inches in front the resonator,supposedly to cut the resonance in the car...the ring is almost an eight of an inch thick,so that cuts down the pipe to about 2.125''...i got rid of that too...i dont remember the brand of the x-pipe(2.500''),but removing the resonator,bottleneck section and the ring inside the pipe made the car a lot more responsive(seat of the pants...no dyno),still NO resonance(im half deaf!),and not loud at all(i could stand more noise)...i have stock exh. manifolds for now,but the ssw are on the shelf,waiting for winter(soon

),along with ported heads,and hi-flow cats.

i know this thread is mostly about the corsa system but i talked to the guys at EES and they told be the bought the B&B tri flow and X-pipe makes the most power on the dyno so thats why i went that route. also had SSW headers and a fidanza light weight flywheel isntalled at the same time as the B&B. i can see the difference on the tach because the needle moves faster. lol. there is some resonance around 1500-2000RPMs but i fully expected it and to me, its actually appealing. i can still have a conversation with a passenger with out rasing my voice at those RPMs which i was a little afraid of. The thing sounds ROOTHLESS when you put the hammer down and i love it. i could actually stand it to be a little louder. but im 25years old and as the saying goes, if its too loud - your too old. lol. i LOVE this exhaust system. it adds that third dimension to the driving experience. See it, Feel it, and now you definately Hear it.

Just figured I'd post an update. So I do miss my old system a little. I miss the ground shaking vibration at idle. And the old-school sound of it.

From outside with the Corsa, the idle sounds a bit, ehh, metallic. More like a boat than a car. And I hate that on cold days the Corsa only blows vapor from the inboard tips. After only a week the difference in tip soot was noticeable.

Also the old system was brutal at 1000-2000 revs, and really got quiet above 2000. The Corsa is quiet in the 1-2000 rpm range. But if you cruise above, it's pretty burbly, you feel like you really should upshift.

Oddly I seem to be getting better economy. Averaging low 17's vs mid to low 16's normally. And it seems to idle smoother when cold, start up quicker, and shut down quicker. Possibly that's just a trick of the sound, and what I clue in on subconsciously.

The sound is great though. And my wife says it's much quieter in the house when I start the car up. I also love the popping burble on just about any lift-throttle situation.
