should i go with a no cat downpipe or a high flow cat downpipe and will the no cat effet the motor at all in any way???
OH and what do you all think what kind of headers shouyld i get as well??

thanks
mike

 

That all depends on if you want to be street legal

 

catted.........

 

this summer im going catless

 

Catted, but make sure it's a spun cat w/ metallic substrate, not a cheap universal pressed w/ ceramic core...

 

it doesnt matter street legal or not whats better like perf. wise?

how do i know that ^ its that ? ha and i can get a down pipe with a high flow cat built in or with just no cat

 

its header not headers. get mangaflow cat

 

i know its header i just ended up putting an s on the end haha opps

 

if you go catless get a rezinator because it will sound like ass. kinda like my car does. i got the zzp 1.75 header and 3in downpipe with a 3in catback & magnaflow muffler. kinda raspy but its not too bad.

 

my tsudo came with a resonator so would i be good?

 

think of john lafontaine when you read this... it sounds like a movie release.

Either the 59920 or 59950, depending on packaging restraints. The 76 may actually work if a fab guy wants to get creative...

 

lol

 

i would just go catted. A nice cat isnt really that restictive and itll save you from all the emissions bullshit you have to deal with later and your car will sound better with one too. Its more of a win with a cat then a lose

 

true so maybe high flow cat then?

 

go cat, your car "i promise you" will sound like **** if you get no cat.

 

catless is raspy..typically sounds like ****..get a hold of clear image automotive..grab ur header..and downpipe with hi flo magnaflow cat

 

I just went catless today....

 

how does it sound man?

 

ok so what do you all think about the gmpp header and the pacesetter header which one???

 

gmpp header is just a honed out LSJ mani if im not mistaken and as far as i know pacesetter is hard to find a DP for ... stick with ZZP, Vibrant, or Clear Image

 

ok good call on the lsj thing i think ur right

 

Mmk, I have the stock manifold, 3" CTI catless DP into a Magnaflow catback exhaust. At idle or at RPM's under 3 grand it sounds effing amazing. But, if I whomp on it it is obnoxiously loud.

I also lost about 2 pounds of boost. Guess my stock downpipe had a clogged cat. Car runs a lot better now too. It feels like it pulls a little bit harder up top.

 

catted please

 

cheap way: catless; if you have a crappy exhaust, this will let anyone else know aswell

right way: high flow cat, exhaust tone remains closer to what it was before the cat swap, although it may be a bit louder, but atleast it wont be raspy
