Got a line on a Borla catback system. The guy wants $250, it is only a year old. Thing is, I don't understand the way this systemn works. Looks like one side is straight through with some different plates to put in it and the other side goes through the muffler....would'nt that make it sound different from each side if only one goes through the muffler? Anyone running one that can provide some insight and do you think it is a good deal? I seee these are close to $1000 new, so the price seems good. Thanks.

 

The different plates feature different sized openings you can use to adjust the flow of exhaust to affect the volume. The most open plate will essentially bypass the muffler, while the closed plate will route the gas through the muffler. The sound doesnt change from one side of the car to the other.... its all mashed together with the million other sounds a car makes.

If the system is solid then $250 is a good price for it being only 1 year old.

 

Exhaust flow will take the path of least resistance. What's interesting to me, is someone might buy a new Borla system and end up running it wide open, essentially having themselves an $850 straight pipe.

 

Exactly, and thats what most people end up doing lol.

 

I'm going to look at it Friday, if it looks good, I'll probably get it. What intrigues me is the ability to change how the car sounds without having to install a different muffler.

 

Its not so much changing the sound as just changing the volume and introducing rasp. Is still a bit of a process to change out the plates, so generally people only change it once and leave it.

 

i was looking at exhaust fo my car its a 99 3.8l with a 5 speed. does the exhaust off a v8 fit on the v6 for just catback

 

I have a flowcrapper on it now and I hate it. Last thing I want is rasp. I've got a magnaflow on my truck and I love it.

 

Go for it, good deal. With even the smallest hole plate the system is loud and will attract piggy attention, etc. but sounds good and the sound is NOT what I would describe as raspy (assuming OEM cat as I have on a 3.8L)! The system still sounds great full-closed, and the ideal is install an electric cutout as well - instant volume control. DMH cutouts are good.

I have this system on my RS -- love it.

 

Ahh, I'm gonna pass it up for now. AC just went out again, got to get that fixed first. Plus I need new tires for my new rims....gotta resist this impulse buying...lol
