I've got a ChallengeUSA 76TA-S 3 inch single exit exhaust system for sale...with a added on pipe to try and help with drone,I used a diffuser so alot of the pipe was hidden anyway.
The drone is perfectly fine under 3krpm at a constant speed, but as with majority of systems there is alot of drone at 3-4krp.
I used a diffuser so a lot of the pipe was hidden anyway.

Made 228bhp with Romain at Eurospec, with intake, manifold and HFC, Romain said he usually gets them numbers with a decat.. so this system is good if you're looking for a high powered n/a or turbo build.

Could do with a more thorough clean up as can be seen and needs new gaskets/bolts

Looking for £500ono Paid £750 last year from a member off here. Collection only Essex/Chelmsford.

Heres hows the exhaust looks on the car, this was before the add on pipe which you'd barely be able to see.

Heres a pic before I removed it without the diffuser:





Also have a Berk 70mm hfc with a boss welded on suitable to AFR sensor £80 delivered only used for approx 6000miles can sort out a bung for the extra boss if needed.

 

Is that an APR wing?, If so pm and you want to sell it PM me

GLWTS

 

PM about the cat.

 

"Also have a Berk hfc with a boss welded on suitable to AFR sensor." I'm not familiar with these yet. Do Berk HFC's not take an AFR as standard? Will I need to do the same if I replace my stock chip with an AEM?

 

which manifold where you using?

was that a 76mm collector, into 70mm hfc into 76mm exhaust?

 

J's racing manifold which I think is 70mm collector.

 

I think the aem disables the o2 sensor so you could remove the o2 sensor and use a afr sensor inplace, at the time I had the freedom to weld in another boss and I didn't have the aem ecu at the time.

The hfc is provisionally sold to dls91 at the moment, just waiting for him to get back to me.

 

Exhaust reduced to £500
HFC still available.
