sports cat for RS2 chipped spec coupe, 100 or 200 cpi?

[avants2turbo]

as above, my coupe failed the mot because the car has the cats removed and the mot man is a tool!

so i want to bang together the 3" dp I was going to make a while ago and replace the cat bypass pipes with a 3" 76mm cat, but which one? 100cpi or 200 cpi, the car has recently been dyno'd at 369bhp and 400lbsft with stock ABY DP and 2 cat bypass pipes into a 3" system

ive found this one on egay

or this one

i know 034 also do a 250cpi cat 3" for 149 USD but how long does it take to get stuff from them, and also is 250cpi going to be ok?

Protecting your business is harly 'being a tool', post 1992 cars need a cat to pass the MOT.

I have a 100CPI cat and it passes the MOT... just, needs to sit on the machine for a while and go through the longer test.

If your going for bypass pipes and only using the cat for MOT get an 200 cell or 034 cat. If your using it everyday you can use the 100 cell

I have the 034 cat installed fulltime as the core is better than the cheapo cats on the market

no im going to keep it installed full time, so you would reccomend the 034 cat?

whats the average delivery time for stuff from 034?

I know Bram, Myself and MattS2 have one installed, no way will you fail an MOT due to emissions with one of their cats if your car is tune is correct.

Delivery is down to customs and whether 034 have stock etc typically it's been 5-7 days for stuff from America recently

Fit a 100 CPI cat and leave it on there, it shouldn't affect performance, can always ditch the centre box if you want more noise. Swapping de-cat pipes on and off is a pain.

I have a RS2,ed S2 coupé with a 3" DP and exhaust system and dual bypass pipes and yes it is a pain in the **** swapping them over every year. my mate has a perrin 200 cells cat i can have for next to nothing that is almost new that i had planned on TIG welding on to the DP. he had it on his 06 impreza wrx sti pse 3. will it be ok for me or will it "strangle" my car and most importantly will it pass the MOT? car is tuned by dahlbäck.

Not that happy with mine, I will be knocking the centre out of it, the cake inside it moves backward and forwards about a inch and half and rattles till it gets hot, its just press in nothing to keep it in place.
