I never really understand why people say this? Is it because it has a lot of drone it must perform well?

In spite of the 3" tubing, it has 2.5" pipes in the res and mufflers. Also the pipe is both perforated, and has those weird mesh screens intersecting it. I really don't see how that would be the best from a performance standpoint. They could have 4" pipes on it, the resonator and mufflers still look restrictive.

That Magnaflow system seems interesting though, 3" everywhere.

I have heard the same thing from alot of people. They say they liked the little extra boost in hp from the B&B. But the resonence was so bad that they couldn't even talk to their passenger. Most people that have corsa really like them.

Simple the B&B is indeed 3 inchs and the most free flowing system beyond straight pipes and has been proven with numerious dyno runs. Also the Mesh screens you speak of which are noise cancelation cones in the series three version or Gen3 of the B&B family for ZR-1 exhaust systems. The earlier versions Gen I did not have those mesh cones and was even more painful in the 1200-1800 RPM range and forget having a conversion in 6th gear. The GEN II version was a resonator mod only or as I called it the oversized centerline fartcan mod that was internal. If you had a Gen III B&B system and you thought that was loud you havent heard nothing yet lol.

And your right performace=sound is a hollow arugment. Im referring to all the dyno runs done on the gen I version which Bob was consistently proven

When I took my car to Marc Haibecks last fall it had the BB system. I spoke with him at length about his experience with BB and Corsa. I certainly could have heard him incorrectly but what I got out of the conversation was his dyno experience indicated that the better torque curves were obtained with the Corsa system. This was for original displacement engines; strokers did, in fact, benefit from the 3 inch pipes.

Depends on the generation of B&B also Marc has a backpressure part to his argument

Since we are on the subject of exhaust I have a question that I have still not had a good answere for. I have a Borla system. And almost a year ago late one night I went over some railraod tracks and could kiss my resonater goodbye. You want to talk about drone! My Z sounded like a Southern Pacific frieght train comming down the road. So I measured the lenth of the res and went to midas and had them cut me two 2 1/2 inch pipes and flared one end just as a temporarely fix until I get another resonator. So my question is does running straight pipes instead of a resonator make for better breathability?

[GOLDCYLON]

I would have to state without a doubt due to the internal baffling on ALL resonators. What I do like about the Corsa Power pulse system is the resonator is elongated at the mid line and has a lower profile than the B&B Fartcan in the middle of the car. I guess we can add Borla to that list. My Car is a stock height and the B&B resonator always hit R&R tracks and speed bumps no matter how fast I went over them or the angle of attack to the problem. (Reminded me of my traction bars days on my Camaro’s when I was 17 lol)

My car the previous owner had installed the GEN I B&B system and upon driving the car home from Houston Texas the resonator to my surprise had been almost destroyed by the previous owner under my car as the front input pipes to the resonator were all cracked and barely hanging on at the weld seams and the underside of the unit looked like it was routinely beaten over the course of ten years. I drove it all the way home to Phoenix in this condition and all I could say to my father who joined me on the trip was What??????


Corsa is the best touring system handsdown but the best looking tip wise IMHO will alway be the oval tips of the B&B system.

That makes sense to me. My car is totally stock minus the borla. When I had it dyno'd at Coreys last month it ran 341.75rwhp 335.50 ft lbs torque. I asked Corey if that was normal for stock. And he said that was a little better than stock. They typically are around 325 for a 375 LT5. Weather those straight pipes that only cost me $30 bucks made a 16hp difference? I just don't know. But the resonator did have a much better sound than the straight pipes. But amazingly the straight pipes don't produce any drone at all which really supprises me.

did they put a crossover or x pipe in the system when they did it ? if not there is a few xtra hp in doing that

[jonszr1]

ps on my spin tec set up it has an x pipe and a crossover back behind the rear end . dont know why they did that but all i know is this set up that they built for me makes good hp. i dont think a 3 in would make any more . jmho
