Hello Folks!
I have a 2014 fist and i want to get rid of my stock cat and replace with either a 3'' DP or gutted cat with stock DP.
Listing my mods might help.....
1.muffler and res deletes to strait pipe( stock diameter)
2. mountune 215 kit with CAI
3. brisk racing sparkplugs
4. soon a snow water meth kit which adds 25 hp max
other little things
I want to rid the cat to get better airflow but the rest of the exhaust is stock. There is a company depot racing that says their 3'' dp will fit to the stock exhaust but I dont like the price and the look of not having a cat! I will use a spark plug defaulter to trick my rear sensor so a retune wont have to be done and actually isnt even possible with mountune files. My idea is to hollow out the stock cat and re attach the dp. The rest of the exhaust is stock diameter so im not sure if a 3'' dp to stock will do anything to release restriction if there is any without the cat. There is an elbow at the end of the dp that looks restrictive! MY QUESTION IS... does the stock downpipe have any restriction points beside the cat? The thing to think about is if the bigger downpipe is even worth it considering it is hooking to stock diameter exhaust (Minus the muffler and res). I hate my cat and want more pops and much more flow but to keep the rest of the stock exhaust because it flows fine as we all know! what would i benefit or loose by getting rid of the cat in general? I am doing this to prepare for my water meth kit. Im sure the car will benefit from no cat but it all comes down to the 3 inch dp or hollowed out cat. Which is best? keep in mind visual inspection. I rather fool them into thinking it is there rather than have a shinny new dp without a cat shell. I could probably weld the old shell on the new pipe for visual inspection!!
Comments from people that have experience with this or knowledge about fist exhaust is appreciated most!
Thanks guys for the help!! If you rather private message that would be fine too or email at [email protected]. Im just torn between the two options and not sure what each will do to benefit me
