I am new to the forum and will be picking up my 1994 Trans Am 6-Speed T-Top car today. It has the SLP Loudmouth Cat Back and I am not sure that I am going to like the no-muffler sound? What are the advantages of having this verses the flowmaster or likewise catback? I will post pics later when I get the car in the garage.

if you plan on doing longtubes and and off road y setup, it can be very loud
i had it 2 of my cars, didn't really mind it...some people really dislike the way it sounds
if in the future you get tired of it, many people will throw a borla xr1 muffler or something similar in place of the resonator

a catback that would be somewhat milder compared to the lm1 would be a magnaflow or a hooker but are still nice and loud but the rasp is cut down alot. do not get a flowmaster catback, i had one on my car when i purchased it from a guy way back in 2000 and i hated it. unless you plan on running true duals a set of flowmaster one chambers would be nice other than that the catbacks they make for the fbodies just plain suck.
its really a hate or love with the slp loudmouths, i personally love the way they sound WITHOUT headers on, and with headers it just gets really loud and i still like it. im one of the few that still like loud, raspy, obnoxious cars.

Here is a example of LM1 from stock Y back. I did and upper chamber cleaning so I had to rev it a few times, so this should give a good idea of the sound. By the way, I like my SLP LM setup, I now have shorty headders and a SLP Y added to the mix, just have the stock cats still on.

Here is a question, I just got my TA today and I love it. Small problem though! It surges or missfires at low RPM's and I cannot run 6th gear unless I am going say 90? Now when I am up in the rpm's it is nice and smooth with lots of power? Any suggestions? Also, seems to backfire quite a bit. Don't know if there is an exhaust leak yet but maybe some of you have run into this? Also where is the distributor on the LT1?

If youre car has headers I would swap the SLP LM1 can out for a Borla can, but other then that is probably one of the best catbacks you can get for sound, stainless with pretty much 3" all the way from the cat to the axle before it splits.

Sorry I have alot of questions. I smell gas when I park it? It takes a while to start it? Fuel Pump? Also it looks to have the factory wires on it and it is at 138k. Could be a serious issue.

The head ache of the opti.... You could be running into a few problems. I had a 93 LT1 before I got the 02 LS1 and had a misfire at low rpms also. I did a plug and wire switch, then did and opti switch and still had the misfire. Sold the car later to a bud that wanted to fix her up and he finally found the problem in the ECU. So the problem could be anywhere from the opti, plugs, wires to ECU. First thing is to get is scanned and see if any codes are on the system, then you will have a better area to start from. Next you can do a plug and wire tune up relatively cheap, but then if you come to the opti to replace, that will be a little more expensive and is defiantly more time consuming. Oh, and the fuel smell means your running rich. I think the pump is fine, but with the misfire going on, its alowing the extra unburnt fuel to build and that may be causing the backfires as well as the smell. Mine did the same thing you are talking about, smell, backfire and misfire. Like I said before, it all came down to the ECU as the problem, but that was discovered from the system throwing a code.

I will have it scanned, and the car came with all of the records. it has had the distributor replaced 3 times and 4 sets of plugs and wires? Like I said earlier, I cannot run 6th gear? I want this thing to run smooth at low rpms. I am not a fan of the Opti Spark! Here is a photo of my Chevelle. Soooo Much easier to work on!!!! And Making 700HP to the rear wheels!! Has just a little NOS on it, Just a little!!
