Hello everyone, I know this question may have been answered already but I need a quick answer. Which high flow cat. converter is best for the ITR? LMK Thanks

 

I don't know the best one there is. My OEM original went bad a little past 200K miles and I replaced it with a random technology cat, its high flow. Haven't had any issues with it. Not sure if I'll pass Northern VA emissions, but I'll see in a few months when I move.

 

Hands down this is the guy that you want to buy a high flow cat from:

smsp and he is Dave.

Renault or SMSP are no question the best high flow cats available for the ITR. Keep in mind you pay what you get for. Both aren't cheap, but extremely high quality and high flow which is what you are after.

 

Agreed.

 

SMSP for sure : custom made to ur need and specification !

 

Thanks for all the replies!

 

Anyone know how I can place an order for SMSP Cat...I went to the link and I don't see where I can place an order? Please let me know..Thank

 

Anyone know how I can order SMSP Cat. Converter?

 

you can try PMing user SMSP here, or email him at smsptech@comcast.net

 

Does anyone know if SMSP is still in business? I can't seem to get any response and really need to get a Cat. ASAP. Please let me know anyone?

 

Any good quality muffler shop should be able to sell you one to your specs

 

It is spring so most race shops are preoccupied with work from teams. I'm not saying your situation isn't important, but consumers are a lower priority when compared with race teams that offer regular business. HyTech and SMSP are not the quickest options, so if you are in a rush a local shop might be your best bet.

 

i had a magnaflow race high flow cat for 14k miles and my h22 burned it out. i highly recommend NOT buying a magnaflow

 

Op what you could is get a straight pipe/test pipe (omni or alike) and weld the factory heat shield around it to give the look of a cat. My buddy had this done on his boosted em1 and it passed Va emissions and visual

 

T1R offers one thru aj racing called a "racing converter" but they don't come with an 02 bung from the looks of it. Has both usdm and jdm lengths available.

 

Interesting, never knew this was possible.

I know that California Catalysts are now serialized. I remember paying 200+ close to 300 installed for an OBD1 GSR replacement catalyst, this was about 4-5 years ago. I don't know if this is old pricing, but it seems really reasonable to me, especially if it will pass emmisions. ( Probably wouldn't pass visual here in California though)

I have a magnaflow high flow cat on my integra in cali and it passed smog and has been running fine, I'm an h22 guy and know they burn oil early and if tunes and ran on OEM pistons/sleeves you will eventually get blow by for numerous of reasons. A cat just doesn't burn out, it's caused by to rich of tune if tuned or oil burning.
