Does anyone know of any bolt on high flow cats for an 03 cl-s 6 sp? Also is there a difference between 6 sp and A/T for this part like there is for others?


Thanks!

There is a cat back called ...random technoloy high flow cat... that will work for the 6speed, the automatic is different.

SEARCH for random technology Cat. i believe excelerate sells them on the forum.

first link with some general info
https://acurazine.com/forums/showthr...dom+technology

and where they are sold

in the first link it should discuss the widening of the mounting plate holes and extending the O2 sensor wires that must take place on the 6spd.

I don't know of any aftermarket cat that is a direct bolt-on to the Type-S (auto or 6speed). The Random Tech cat is a direct bolt-on for the CL-P, and as stated earlier, requires slight modification to the flange. Personally, I would buy a universal R/T cat (with the larger inlet) and have a muffler shop weld the correct flange(s) to bolt up to the factory down pipe and b-pipe.

i have the rt cat for my 6 speed. rt only makes one model and it is a direct fit for the cl-p as stated. i got it to fit my cls6 with minor modification. nothing you could not do yourself with a drill and drill bit. basically need to drill the holes out a little larger so that the holes will line up better to the header and b pipe. excellent mod

you got to mess with the flanges. also the cl-s cat is longer than the cl-p's

are you sure? the cat is different, but the physical length i believe is the same, since all catbacks fit the cl-s and cl-p.

The RT cat bolts up to the Type S and Premium model jsut the same. Both require extension of the 02 wires, but the Type S requires slightly enlarging the holes on the flange on the B-pipe to cat. And from what I understand from other members you don't even need to modify the flange if you have a stock exhaust.

not 100% sure, but in this thread: https://acurazine.com/forums/ramblings-12/first-napster-now-189511/ biglizard/gm and mclarenf lead me to believe the cat on the cls was a little longer
