XForce Performance Exhaust System
Category: Complete exhaust systems


The XForce E4-NS13-CBS is a cat-back exhaust system listed to fit the Nissan 180SX from 1988, priced at $799 RRP. It changes the rear half of the system and is sold and fitted at our Illawarra workshop.
A cat-back replaces the run behind the catalytic converter through to the tailpipe, leaving the cat and the engine-side pipework as the car left the factory. For this NS13-coded listing the supplier records the cat-back type and the Nissan 180SX fitment from 1988, but not the diameter, material or muffler configuration — so we read those off the kit rather than quoting figures we can't see.
The slug names the Nissan 180SX and the listing carries two concrete fitment matches from 1988. The supplier leaves the engine and sub-model blank, and feed data can be imperfect, so treat the fit as listed and confirm your exact 180SX build with the workshop before ordering. We'd rather verify it than have a part turn up that doesn't sit right.
Behind the cat, the cat-back is where the note and rear flow are set, so swapping it changes the back-half character without touching the emissions hardware up front. On a light rear-drive coupe it tends to give a fuller sound than the original — louder than stock, not a quiet replacement. We hold no sound data for this part, so that's as far as we'll characterise it.
Oak Flats Muffler Men supplies and fits XForce cat-back systems in-house across the Illawarra. We check the part against your 180SX's hangers and rear layout, fit it square and seal the joins. Send your build and we'll confirm it against the listing before booking the bay; the recommended retail is $799.
