What did you do? Cat-back? Did you eliminate the downpipe all together or what? I'm bout to take my car to the shop once my high flow cat & muffler get here and just wanna make sure I have them do the right thing...

 

turbo back exhaust, includes downpipe and back, and put a 300cell high flow cat in. sounds good, compliments the stuff in my sig.

 

turbo back, 3 inch tell high flow cat, 3" tell muffler that does nothing to quiet the car down

 

what is a tell high flow cat JEFF? I was just going to get the test pipe. ...

 

i had to pass emissions. i was 4 times over the legal limit

 

so my question is this guys... i bought a labree high flow cat with a remus muffler...

the piping in between is what i need to get made, and im just wondering about the down pipe with the flex bend in it & if its needed or if i should just go with straight from cat to muffler

 

3" mandrel from cat to muffler

 

isnt 3" a little overkill?

 

yes, unless you are like tomritt, or jeff, or anybody else with a big fat turbo setup. if you have a ko4 or ko3...2.5 is sufficent.

 

so should i pay for a downpipe and get the exhaust custom from there? or just bypass it or what?
