hi, l have an 04 sti fitted with the ppp, lam looking at changing the back box for a second hand tsl firestorm, will it fit ok to the centre section and will it catch at the back,will it also make the car run better or worse than the ppp rear box, many thanks, all advice welcomedcheers

 

will fit mate. I had one fitted to my 53 plate sti ppp. Ran a bit lumpy and never gave the ecu a real chance to adjust but ended up swapping the Prodrive one back on
The firestorm was bloody loud and didn't appeal to me but just my opinion. Additonally when I fitted this to my Classic it actually cost me power over the Scoobysport one that I had on before.

 

Dont mean to hijack your thread but if you decide to sell the ppp backbox please can i have first refusal. After one to replace my standard wrx unit.
Many thanks!

 

Mines coming off in a few few weeks as I'm changing to a 3" straight through system in anticipation of a turbo upgrade.

Its coming off a 53 plate sti and has been on the car for 7k miles. If Andy's not getting shut of his give me a shout although I may want to sell the entire ppp exhaust system as a whole. This will include the Prodrive sports cat downpipe; decat pipe for the 2nd cat and the Prodrive embossed back box. It will obviously pass all mot emissions and is warranty friendly.

 

RLE, I'd be interested in the whole thing mate.
PM me if you decide to go ahead and what price you want for it.
Matt
