I finally broke down and ordered a downpipe to get rid of the restriction, the bulk of it. It's a 2.5" TruBenz/MBE catted aluminized dp. Besides a "chunky difference" in accleration, does it provide better throttle response?

My setup:
2.4 Throttle body
SS/TC catback

Aluminum is ok to have as i'm in FL

 

Not really any throttle response...just breathes better

 

you'll notice better topend should sound nice post a vid when you get it installed

 

Top end should sound nice or Rice?

I dont actually know about the 2.2 but my friend has a 06 ss sc with a catless dp and stock exhaust and it sounds like CRAAAAAP

 

catless will sound crappy but catted might have a nice rumble you wont here them coming mile away

 

It's plentiful loud with the SS/TC muffler as it is straight flow. It's growing on me though.

 

Hey with having the 2.4 Mani do you also have the 2.4 throttle body and the 2.4 MAF? What results you notice?

 

Do you have the 2.4 MAF and TB? What kind of power you see

 

It's not made out of aluminum.

It is called aluminized steel. It's a coating which helps to prevent corrosion.

 

The airbox/maf assembly in the 2.2 and 2.4 engines are the same. I only upgraded to the 2.4 throttle body. It's the 2008 6-pin.

 

2.4 TB is direct plug and play

LSJ TB is more involved but has better gains

 

Don't you need a tune with the LSJ TB? I know the 8-pin part and please don't give me any more gain ideas the DP is hurtin enough lol!

 

yes tune is needed

you see lots of gains with a tune...one of the best mods

 

if i did 2.4 mani and tb with a catted DP and a tune, what do you guys think a 2.2 will gain for hp? and i have a an intake as well.

 

i put down 156whp with the same stuff except the 2.4l manifold and i think the earlier 2.4l manifolds are bigger then 09 and up different designe just dont know which one flows better, wheres a flow bench when you need one lol

 

forgot to add this i pick up almost 15 whp in mid range

 

So I just had the dp installed. No CEL as of now but the guy said give it a day or a week if that happens. Due to the SSTC muffler it's a tad louder and raspy at high rpms. I can tell it performs a tad better.

Couple of notes:
Auto tranny now shifts a little harder
Stock dp has 2 cats......yes 2 cats but what reason?

 

my check engine light didn't turn on for about 4 months, 2 cats for emissions

 

Weird as most dp's have one. I'm not even sai lol. What did you do to solve the cel..defouler? I'm also gettin another muffler for a lottle silence.

 

You could just leave the CEL on. It doesnt affect anything.

Otherwise get a tune

 

^ thats what i did

 

Ok so I'm impressed of how the Dynomax Super Turbo sounds. Would this muffler quiet the system some alone Or should I get an 18" resonator with it?

 

always get a resonator...

 

Ok guys i'm gonna have an 18" magnaflow resonator with 2.5 2-bolt flange welded in there. Guy said he'll have the part in today but by then he'll be too busy (full appts) to have it done today. :/ I did talk about the Turbo muffler but it was a problem to him when it comes to fitment and that it will hurt performance hahaha. I'm aware of a slight performance sacrifice then again I didn't wanna argue with the guy. So resonator it is, and muffler at another shop down the road. By then I'll have my taxes

That aside will the resonator take some of the rasp (not all of course) and tone her down some? Hopefully be mellow enough not to **** off the cops.

 

my buddies IRL had badmab shorty with a 3" catless midpipe and stock exhaust and it sounded pretty good... it was a bit louder than i expected tho.
