What Cat would you recommend with a Toda Header and Fujitsubo RM01a exhaust combination? Obviously It would need to have 2.5" Collectors and an O2 bung but I want the best quality and fitment with these parts. Can anyone help me here please? Thank you

 

I went with the password test pipe since it was adjustable and cheap.

 

Right on, did you get a check engine light with it?

 

if a cat is a must have.. order JDM OEM DC2R catilytic converter from Hmotorsonline.com can go wrong and are fairly cheap

 

Tsk tsk, I thought you were leaving it stock.

 

what's your email?

 

i have the T1R test pipe with a TODA header. it is my first test pipe, i think the finish and fitment is good, but other than that, i cant tell if is good or not.
yes, you will get a check engine light.
i had to weld a bung in it and did the O2 extension trick and that solved the check engine light issue.

if i would do it again, i will probably get a 2.5" collector cat. not test pipe.

 

I've got a Toda header with a car sound cat from SMSP and a T1R 63mm exhaust

 

Thanks for all the responses, I will look into them. The stock JDM cat sounds nice because I want the car ro stay mostly stock. Im not going all out just want a few tastefull bolt ons for a little more power thats it. I may not do it but am thinking about it. Thanks

 

PM me

 

If you want a stock like cat that'll open up a bit more power and keep relatively the same sound level, look into SMSP. He has many tests with his high flow cats to help you best choose one to your liking.

Thanks for this link, these look great do they make one JDM length with o2 bung and 2.5" Collectors? Also I really like the Random Technology Cats but I don't see they offer one for the Type R.

 

Dave, at SMSP, will make a cat to any length desired. Just call him up if you're serious and he'll get you taken care of.

 

Carsound SMSP Cat,Dave'll hook u up! Can't go wrong, had mine for 4 years/10k miles and very happy with it! Best part is you won't pollute like a Test-pipe and won't stink up at red lights causing your girl a headache

 

Right on, is this Carsound the same as this one http://inlinefour.com/carunhigcatc.html ?
Is this one a good one to buy I really like how it has the o2 Bung, 2.5" Collectors and is the same size as JDM Cat.

 

I'm running a SMSP cat. OBD2, I even had Dave add an extra bung out to the side for the wideband when tuning.

 

I have tried to email Dave but the email address on the site must be wrong because it keeps being returned undelivery notice.

 

Before you run out and buy a carsound cat, search around. They had a bad failure rate for a while. Rattle cans that pieces would fall out of the muffler.

 

Thanks for the advice, I would prefer an SMSP but the email address isnt working to get a hold of Dave.

Don't get test pipes. The air is dirty enough without polluting it with your car's emissions.

 

Thank you,

I got ahold of Dave and will be purchasing one of his high flow cats with 2 O2 bungs. I really hope I dont get an engine light. Thanks for all your help.

 

I have the exact same header and exhaust as you. After going thru several test pipes and 02 sim fixes I switched to a SMSP racing convertor and it has been the best move I could have made for my exhaust set up.

 

Nice, is the racing convertor the 400 cel cat Dave sells because that is the one he recomended to me?

 

smsp modifies carsound cats so they won't give is as easily, and does a hell of a job at that.
Also one of the better mods i own.
