• How much hp would a High-Flow cat add if any at all?
• My friend had an integra with an Apexi N1and it sounded good. It wasnt to rice and didnt sound like a pissed off bee going down the road, very deep and throaty. How do you think an N1 muffler would sound on our cars?


...boredom..........

 

i am about to replace my exhaust with 2 1/2 SS piping, magnaflow hi-flow cat, and a magnaflow 2 chamber muffler or a borla type muffler into a 3 or 4 in SS tip. i have a technician at work to do all the welding( since i am a bit rusty no pun intended lol), i also got a quote for the same thing to be done by a performance shop in my area to do it with the same parts and including labor for $230. i just hope the cars computer agrees with the install.

 

awesome, let me know how it goes and post pics when its done. I wanna see!!!

 

what's the stock diameter of the exhaust tubing? sucks that mitsu had to have the cat as part of the pipe...

 

i think its 2.5

 

yeah? damn, no wonder RRM says axle back is bascially all you will need. 2.5" is perfect and i think it's illegal in some states to tinker/change the cat so looks like cat back exhausts simply aren't needed. what we need now are headers

 

Pretty sure that'd be ALL the states. It's a Federal law if I'm not mistaken.

 

In Texas its illegal for a shop to remove a good cat and replace it.

 

so what if you take a sledge to it on purpose?

no seriously, someone must have done this

is it legal to get a high flow cat to replace oem cat then?

 

yes because the emissions are still under control with the hi flow cat. there are ones i have seen that are for offroad use only. but the one like magnaflo carries is approved for replacement.

 

headers wont be out for a while...

 

i wish it was easy to make a header

 

i myself have questions bout the exhuast, my friend does alot of welding for his own car, instead of going out n spending a wad of money, n my sisters boyfriend is givin me his old (not old but doesnt use them so im gettin them) Greddy Ti-C exhuast, so i was wondering if my friend welded me the pipes n the exhaust together, would b any defects to the car itself? or would it not b compatable?

 

It would work fine. You'd be making it from scratch, so of course it would be compatible.

 

thats nice to know that itll only cost me bout 40 bucks for the piping to b done, but my friend will prob charge me less bc im sellin him the other one.
