SLP 2 Out The Left - Opinions please Faced with the need to upgrade my catback (it's currently the 2.75" stocker with a 3" Spintech split case), I'm looking at different setups.
I really don't like the tips of any catback on the market (I have 2 turn downs - gives clean profile). I don't like the look of dual dual tips (i.e. Hooker, etc), and I don't like the big cannons of Magnaflow. I also need to quiet the car down some (no Loudmouth for me then).
So, the 2 OTL seems like an alternative to the norm. It may be the ugliest looking catback for some, but as you have read, my preference is peculiar.
Any comments on flow & sound?
Even better, any clips?
I'll be running a cutout at the I.
Ps. I'm losing 20 hp with current setup, dyno proven with cutout open.

If you like dual turndowns then you could get the SLP
CME or dual-dual (the latter, probably cheaper) and
just not put the tip piece on - substitute the turndowns
there. I had a wild hair to do this on my CME anyway
(it comes back every time I spend an hour polishing)
but I haven't gotten a way to nondestructively remove
the tips & plumbing yet. I think the "black chrome"
turndowns would go better against my silver car than
aluminum-on-silver CME.

Another alternative is to make a 1OTL catback. Dynomax sells the 3" over the axle pipe and ipipe. Then you can run any muffler you want. Im runnin this with an ultraflo muffler. Its very quiet from idle to 2k, then the drone and rasp starts kicking in. Even then its not too loud. If I were to do it over again Id go with a magnaflow muffler. They make one thats even bigger than the ultraflo muffler I went with. If you run a big muffler it can be as quiet as stock even with headers and ory.

I love my 2OTL. It sounds great. I used to have it on my 94Z, and I moved it over to my 98Z.
I disagree about it being loud. It's actually pretty quiet, and sounds MUCH better than a Borla or Corsa (IMHO, of course - to me, Borla's too blatty, and I just didn't like the Corsa). I like the sound of the Hooker too, but I prefer the SLP 2OTL.
It's about the only product from SLP that I do like, in all honesty.
I really like the sound of my car through bullets off the headers
but since I'd probably get arrested if I drove to work like that, I'll stick with my SLP.

I've actually owned and tried about 10 different exaust setups with and without cats etc. To me the 2OTL is the best. I had it a couple years ago and sold it to try a mufflex setup and after a year of pain and not being able to talk to my girlfriend in the car, sold it and bought another 2OTL.
It is NOT loud. Sounds PERFECT with an offroad y-pipe and will be even more mellow with the cats. Nice rumble at idle and somewhat quiet until you open it up and then it sounds healthy.
Plus it's stainless steel and will last you forever. And you can even polish it up to a mirror finish if you want.
I generally lose .15 in ET with the exaust capped up, but I'm running high 10's low 11's so it does restrict me a little. Not enough to worry about on the street though.

I've also tryed 5 differ exhaust cat-backs...
The 2OTL is the last one that I installed , & it's staying on !!!
The best of both worlds, it's good sounding & makes power...
12.52 @ 110.91 best ,on just a bolt-on 3.23 A4 car, with street GSCs , & stock convertor...

If it's good enough for a 10sec. car, it's good enough for me. THANKS FOR ALL THE COMMENTS!
The current Spintech in place is a Sportsman series and is loud and too raspy. It sounds really mean at WOT, but then again, I think any catback on an LS1 would sound mean @ WOT. I also like some rasp (ever heard a vintage Ferrari?!).
I drive the car every day. Car needs to be "wife"able again.
I really want true duals/ x pipe, but don't have the $$$ to run it out the rear, plus I would want to fabricate it myself and I don't have much spare time. Before-the-axle dumps would get probably get unbearable after the novelty wears off.
Therefore, the catback.

I have also tried about 10 or 12 different exhaust setups (with and without ORYs) on LS1s.
2OTL was nice and was my favorite until I switched to Bassani. I liked the sound of my 2OTL but I could no longer stand the gay look of that exhaust on a T/A rear bumper. I think it looks great on Camaros and Formulas, but NOT T/As.
Bassani had just released their catback when I was ready to switch, so I thought I'd be one of the first to try it.
I was very pleased and much happier with the sound, fit & finish, and general look of the Bassani catback over my 2OTL. But remember, the Bassani setup is quite a bit louder than the 2OTL so that may be a factor for some, but there is just as litte rasp with the Bassani setup as the 2OTL I had. Only difference is that the Bassani is a better fit, and quite a bit louder.
As far as power goes, I have no dyno or track comparison number on the Bassani setup, but you can look straight through the muffler, so I'm sure it flows great.

You can go here: http://www.thunderracing.com/index.c...ategoryid=1051 to see pics of the system.
The whole system is 304 stainless, and the tips are high polished to look like chrome. As seen in the pic, there are extra hangers at the ends of the tail pipes (like SLP dual/dual and some others have) to keep the system from bouncing around and banging like my 2OTL did.

99blackbird T/A: I'm sure it would sound great, and look great on your '91 RS. Don't get me wrong, I still like the 2OTL system a lot, I just think it looks stupid on a T/A since there are bumper cut-outs for tailpipes on both sides. Now, if you wanted to change to a Formula rear bumper cover (I've actually seen some T/A owners swap to a Firebird/Formula rear bumper cover, looked pretty good too), it would look great
wow, I was actually thinking about this same catback the other night
I know i can build my own duals cheaper, but i dread getting around to it
So now my exhaust is up in the air. Either 3" duals/dumps, 2OTL w/cutout, or stock Z28 with cutout (have 3" OR/I pipe for either)
