downpipe question

[richard cash]

hi, im looking for a downpipe for my brothers supra and came across this:

i just wanted to make sure these will replace both cats and what actual power gains he can expect form it.

Don't know if anyone has used that downpipe. What mods does he already have? TT or NA?

Welcome btw :)

standard UK TT apart from 4" catback exhaust, i think he just wants to do the basic mods first. Taking off the decats, upping the boost to 1.2bar, fuel pump and FCD. This should see him to 400BHP yes?

Around 400bhp for bpu yes. Not quite sure about that decat tho. Maybe someone knows more than what's let on. Failing that Whiffbitz make a full one peice decat

Richard you'll need a specific down pipe to fit the UK Spec Supra, buying the correct one off ebay can be a bit of a gamble.

I would suggest fitting 2 individual cat replacement pipes (rather than a single pipe) as it makes it a lot easier come MOT time to replace the 2nd cat to pass the emissions test. The guy to contact is Chris Wilson he will be able to supply you with correct cat replacement pipes specifically for a UK Spec Supra. Drop him an email or give him a call.

Oh and :welcome: to the club BTW.
