i own a classic 95 sti import with a stainless exhaust system and want to put a de-cat downpipe on before a get a remap.what kind should a get a where from and how much?can fit myself so looking for a buy it price.

 

Have a look at Hayward and scott on the web they make quality exhausts the price is listed.
As for fitting it can be a bit tricky if your not that good around a engine bay there are plenty of old threads about this.
Fitting from a dealer is between £60.00 - £80.00.

 

hi mate ive just recently fitted a japspeed decat downpipe to my 1994 wrx it was about £134 delivered from 2fast2cool on ebay bargin, its good quality & came with bungs & gaskets only think i would say is it was abit tight fitting onto the studs on the turbo but it went on in the end, & as above its abit trickey to fit yourself on a driveway

 

cheers mate.no probs with fitting it as a mechanic and its been of 5 times now due to gearbox troubles.

 

got a 04 wrx and thinking of getting a de cat down pipe from ebay, and a stainless system from powerflow but want to keep my prodrive back box. any suggestions or problems?

 

Any T304 stainless-steel 3"-bore "Bellmouth" (fully open) design is the most optimal.

Check on eBay - there's always at least one crop up on there in any given week. Expect to pay £60-100, depending on how many bidders the auction attracts, etc...

NOTE: Make sure the centre-section end of it is the same size to mate to the rest of your system i.e. either a genuine 3", or a stepped-down OEM-sized 2.5" welded in end-section, as appropriate.

 

i think the prodrive back box is 2.5 so prob have to consider getin a new backbox
