magnaflow or borla
hello glad to see a page dedicated to the sweetest gen of all time.i have a 87 iroc.z 355 currently with a flowmaster on it and its getting a little tired in my mind i was wondering if someone had a borla and a magnaflow that i could listen to as im torn between these two .im also looking for some feedback as to which u think is better for street use .i live in canada so emmissions are not a problem here .thanks alot.
I thought magnaflow did not offer a system for the 3rd gen anymore or something?...Hmmm?..well, IMO the Borla is way overpriced so i would not even consider that.Personally I think the Banks stainless kit is by far the best value for your dollar.I am sure some others will chime in here with their opinions

The banks kit is crossflow, right? Crossflow mufflers are stupendously restrictive, where as the borla kit is straight through so it will be inherently much less restrictive, although I have not had either one, but I'd opt for a straight through muffler no matter who the manufacturer is.

I guess that Banks has a muffler with two tail pipes on the left side, but that would still be more restrictive than a straight through. My original post was in regards to the guys who are using the 4th gen crossflow with the 3rd gen intermediate pipe.

I am thinking that the 3rd generation tailpipe version (both pipes exiting on the drivers side) should be straight through. I really do not think that there will be much, if any, noticeable difference. Does anyone know for sure?
I got an email quote from www.torqueandchrome.com and a telephone quote from www.enginetechandfab.com and the price from entec was almost $40 cheaper shipped to my zip. I talked to Ken at entec and I was very impressed with his honesty. He was very helpful and seems to be a very decent person. I mentioned learning about the Banks system in this forum to both vendors. Entec's website is very new and although it does allow you to order online it does not seem to have, at this time, secure online ordering.

The Borla would definately be less restrictive if you ran the exhaust with an open adapter plate on the passanger side.
If you are using the full blocked plate in the Borla all exhaust would be going through the muffler and out of the drivers side just like the Banks 3rd gen (tailpipes on drivers side). I have no idea which would be less restrictive.
IMO, if someone has an exhaust cutout then a Borla plate system would be redundant. Choosing depends on needs and budget. I personally like the looks of opposite tailpipes on the Banks 4th gen better. I was not too keen on the oval tips on the Banks 4th gen at first but the more I think about them the more I like them.

Banks has both..a straight through muffler for the 2 on the left exit and a crossflow for the opposite exit.maybe the Borla will outflow the Banks SLIGHTLY (maybe not?) ,but regardless is is worth twice as much?...not hardly

The borla is the best flowing exhaust for our set-up. I am going to buy it, but for every person who had a good experience there was one who didn't. Plus the catback doesn't go all the way to the cat. You will need to buy another piece of pipe to attach the catback to your cat. That was not acceptable for me with a $700 system. I got the Hooker catback instead. Flows very close, so maybee a 1hp difference(if that) and it is less than 1/2 the price. Tons of people have installed it and it looks great, sounds great, and I still have not run into anyone with fitting problems. The only drawback is that it is aluminum. Thats not a big deal really, at least it is not for me at this point. The stock POS system lasted 20yrs so far just fine, so this hooker one should at least out last the stock system.
