Hey guys.. Newbie to the site here. Ive completed quite a few mods, and am looking to install headers and resonated high flow cats.



Ive looked around for header recommendations but have seen very little on this topic.

Any recommendations for 2011 IPL coupe??

Yes yes... Im the guy who purchased and ipl and modding everything. HA
From what I see this is a bad move... but what can I do now..
I guess ill be riding around in a non-stock Ipl.

 

i dont suggest headers cuz of the cost and you will gain less than 10hp, i gained 8 hp and spent 1300 cuz i replaced an o2 sensor because they got stripped when i tookthem out and it cost 200. i wish i would have gotten a 50 shot of nos and not hurt anything (seriously). btw these cars have headers on them stock thats why theres not much gain.

 

Thoughts on Hi flow cats then without changing headers?

 

AMUSE r1 titan headers...

 

for high flow cats i think fast intensions takes the cake. they also have resonated high flow cats available

 

i got 10 hp from stillen hfc

 

^^butt dyno or paper dyno?

 

ru quoting me? dynoed before and after same day and got an average of 10 hp throughout. it was 9-11 the whole time.

 

 

i dont know if youre being sarcastic or serious, but thanks anyway!

 

Go with the Super Charger kit from GTM.
I have a 2012 IPL putting twin turbos in the car (cost about $15 grand), but you can get a supercharger for about $8 grand. add 150hp and it would be a blast.
Don't waste the $$$ on headers. The car is already maxed out pretty well with the IPL setup.

 

That's such good advice, don't spend 1k , spend 8-15k .

 

stillen headers i installed mines about 8months ago more power and a deeper exhaust sound, mind you though it cost almost the price of the headers to get them installed

 

Yeah, I guess it depends whether you're going for aesthetics or power. If it's power you want, then FI is the most efficient means of getting there. That said, I put a stillen cai on my ipl, but that's probably the only performance mod I'm doing.
