I love the low rumble on my 08 WRX with N1 exhaust, but it is a bit excessive volume wise. If you're looking to give your neighbors a break, this silencer is probably the cheapest and most effective solution, short of a whole new exhaust system. What surprised me the most is that the exhaust tone with the silencer in is still deep and aggressive, and not tinny or sharp like most silencers. The fit is very snug on mine, so I haven't heard any rattle yet. I have also noticed a fair loss of performance, but that is to be expected when greatly restricting exhaust flow. Overall, this thing works great and I'd say it's a great value.
Purchased for my 2001 Celica GTS with Invidia N1 catback. Fit great, snug enough to avoid rattle but not so tight as to be difficult to install or remove. Attached with the included nut and bolt and it hasn't shown signs of loosening yet. The noise reduction is great, car sounds like it has stock exhaust at idle and is a good 40% quieter at higher RPMs. The welds are ugly af but solid, for the price I can't complain. Recommended for road trips or not annoying your neighbors!
Measured around with my caliper and it was about 98mm diameter vs the inner diameter of my N1 exhaust which was around 102mm. It sound like complete garbage with it leaking around the rim and not just from the middle hole. I put a rag around it and it sounds so much better ( like it should) when the sound is only coming from the center hole. Oh, and the welds were horrible with holes. Very disappointed with quality control.
Not sure why some say the fitment is good and some say its not. Well, mine is about a mm too small around my N1 exhaust on my 08 WRX. I shouldnt have to modify anything just to make it do what it should. Yes, it definitely lowers the volume down but because of the fitment, it rattles at idle and certain rpm. And because of the poor fitment, if the bolt/nut ever falls off, the silencer will definitely fall out and could cause a serious accident and/or damage to the car behind you. Ive had other I will be taking mine off to 'modify' it and create some notches/bends on the inner tab to make it fit better and hope it doesnt rattle, on top of purchasing a lock nut for it.
Just the right amount of silencing yet still gives you a growl when you step on it. I do recommend drilling and adding a second screw to hold it in place better so you don' t get a vibration noise.
