one quick question, i was thinking of buying a Borla catback and i was wondering if it is street leagal in both sound and emissions. If it isn't can some one tell me of one that is, thanks.

The Borla and SLP catbacks are both legal for emessions...in fact any cat back system (custom or prefab) should be legal as long as the O2 sensor and cat aren't touched.

As far as sound, the Borla will be fine. Ths SLP is legal, but it is loud...you might get unwanted attention, but it's legal.

EDIT: BTW if you're going for performance, SLP or Milzy Motorsports exhaust will give better gains...MMS is more expensive and SLP is relatively cheap. Both are good systems though. :)

Will SLP and MMS cat-back give you more gains than Borla on a GA with just a CAI? I really wonder if I can gain more low end power(to spin tires off the line), if I switch to a smaller piping?

no..u want a bigger piping then stock but as long as u are reasonable and don't go huge and loose your back pressure.

2.5" is a good size and gives good power

and why are u wanting to spin off the line so bad, that is a bad thing u know, a little squeel or such can be a good thing based off of the friction from the tires and the power of the car and yadda yadda a little spinage could get u going faster, but if u are smokin them, it wont help u at all

I agree with Bill....why? Maybe for showing off, but it's not good for the drivetrain, tires, or anything to spin on a launch. If you really want to spin then to show off, get a manual and drop the clutch.

Ok, I don't want more low end power for burnouts. I just think that low end is better for in-town driving, which is mostly what I do.

I was wondering because I want to either keep the current SLP piping, and get a new muffler and tips and maybe add a resonator later,

OR

just ditch the whole thing and get the Borla cat-back.

thanks for the advice and it sounds like SLp is the way to go one more qustion thats bothering me though, why is borla alot mor expensive than SLP, Is it beacuse they made from diffrent materials or someting elses?

no proof at all to that statement....but I agree that you're better off with either of those. With the small power differences between the 3 you're better off going with the cheapest. Unless you want the most quite one then go with the Borla

Ok, basic question for everyone, I am going back and forth between the SLP and the Borla Cat back exhaust kits. I am open to suggestions. Basically what I want, is a deep grumbly muscle car sound, but it doesnt have to be louder. It just CAN NOT sound like some stupid little import that resembles flocks of bumble bees.... thats just not right for any car. Thanks

@MW15and99 I'm going for the same as you, I've been leaning towards the flowmaster 80 series based on what I've listened to at exhaustsoundclips.com you should check it out

EDIT: here's a link for you to make it easy (http://exhaustsoundclips.com/phpbb2/dload.php?action=category&cat_id=42)

Borla or SLP on a V6 GA WILL NOT sound like bumble bee at all.

IMO you need to hear a few and then decide. The power gains between any of them, Borla, SLP, or a custom setup are negligable. If I still had my GA and was going to do it over again I would buy the SLP and use a Magnaflow muffler. The SLP muffler is just a little too raspy for my taste especially when you back off of it.

There's virtually nothing you can do to the V6 to make it sound like a bumblebee. I do agree with the guys that say Borla is overpriced. You can do a complete custom system for less.

BTW.....there were very few GAs that sounded any better than mine did with a custom Magnaflow cat-back. Kelly, 99grandamse, currently has my old system on his GA so if you happen to be going to Albany this year you can hear it.

If you are going to buy a SLP catback system you better hurry up. I believe there's a post out here saying it's going to be discontinued? As far as Borla, I love my setup, if you're looking for low-end torque,...Borla because the pipe is 1/4 inch smaller. A SLP will beat a Borla setup at top end though. Another thing to consider are the exhuast tips. There's no comparision, Bola tips are superior.
