  • Slp lm 1

    Looking for a complete SLP LM1 catback for a 1998 firebird transam..preferably used. I know some of you may have one and are just sick of that drone; I cant wait to hear it everyday! Let me know what you want for it and hopefully we can work something out!

    Thanks guys and gals

      I love the loudness, just not so much on over 100mile trips.

      i have a borla for sale thats, about 1000x better, looks better, and sounds sooo much better.

        lol trust me coming from a guy who has had several different catbacks, the drone and loudness gets old super fast, hope you don't have headers.

                do you have the borla connected just to the y-pipe off the headers or do you also have a cat?

                  I heard the same set up as I want to run the other day..Im surprised because most of us here only drive our cars for a couple months out the year anyways so we should be dying to hear that beautiful sound when we can..

                  Like i said, ran into a guy the other day with a 97 z28 with an LT4 swap; long tube headers and O/R y with LM1 and it sounded great! Plus his was an auto, so I think I can manage with my 5th and 6th overdrive gears..

                  If you havent heard it in person then you have to

                  opinions very i guess and i appreciate the input!

                        Then be preppared to hear lots of RASP. LT + ORY + LM = way too much noise.
                        After a couple weeks of that you'll be looking for a muffler of some kind to replace the resonator.

                          HEADERS + LM = sweet sweet sounds

                          Love my SLP only thing i hate is how low the stupid thing is to the ground. But ya the sound gets old if on long trips. Thats why i installed SOUND DEADENER . Now its prefect. But like said earlier, we only drive a few months out of the year and how many long trips do you plan on taking?

                            exactly I only daily drive the car in the nice months which here in michigan are a dime a dozen so I think Ill manage.. and I really dont drive the car on any longer trips, I mean who wants to see a white Firebird Formula anyways right?

                            I think Ill manage for the time being untill i can afford to run some electric cutouts and then Ill think about the muffler..but I liked what I heard from outside the car and in..Im sold on them!
