about to redo my exhaust, im wanting to do SLP LM2 true duals

for the high flow cats which ones do i need, summit has 2 pages of them

X-pipe- the magnaflow, is it the best one to get, 2.5 or 2.25

the LM2s only come in 2.5, should i reduce down or just run 2.5 all the way out

thanks ken

 

o its a 07 fx4 crew cab if it makes a difference

 

2.5" will work. some guys run 2.25" but 2.5" will work. Some guys state " it wont give you as much low end torque as 2.25" will"
magnaflow 94106 high flow cats.
X pipe 2.5" (make sure you keep the X pipe as close to where the stock Y pipe would as possible
LM2s 2.5"
and 3.5"-4" tips will look the best. How are you going to exit it?
make sure you dont touch the air:fuel ratior sensor in between the end of the manifolds and cats. also, make sure you plug in each o2 sensor AFTER each cat, that will keep your CEL off.

 

so the A:F sensor is before the cats and the O2s are after?

im more then likely going to 45 them behind the rear tires with 3.5 rolled stainless tips

which X pipe will i need?

 

10791 would be better, that one is more meant for trucks. 10781 belongs in Corvettes and Mustangs mostly.

 

correct. you can even crawl under your truck and check it out for yourself.

 

i believe yall two...i read enough topics in the last 2 weeks on here to tell yall know what yall are talking about

how obnoxious will high flows and slps sound, should i try stock cats first, i want loud but not wake the neighborhood up glasspacky loud

 

high flows and slps will wake ur neighbors up. i would try stock cats first

 

well i got my slp lm2s ordered, and talked to the muffler shop. the guy said 350 for building an x-pipe, running all the pipe installing mufflers and 2-3 1/2in tips

i think i can get him to reuse my tips from the exhaust i have on it already which can save some money

does the price sound decent? this muffler shop is normally kinda priced high but does good work.

 

ya thats a pretty good price.
