1320 Performance B series UEL Twister header GSR SI B18c LS B20 vtec B18 honda

Overview:Ordered Wednesday night got it Saturday afternoon. Amazon told me 5-6 days so happy about that. Product was well wrapped and packaged. Everything was properly sorted. Wasn't too hard to install. Some things took elbow grease/ force. The down pipe was hard to keep lined up to tighten (I was by myself in my garage). Downpipe to test pipe was hard to correctly tighten. Donut wasn't crushing well and the bracket started to rotate over the edge. So I had to do less tight on both. I also couldn't use a washer for one side because the nut wouldn't reach. If they're a hair longer that would have been perfect. Non car guy neighbor said while it's louder, it's a great improvement over my old exhaust. Stated it sounds way deeper, just needs the rasp cut down.TLDRPro's and Con'sPro's:-Shipped fast-Well organized-Simple install-Sounds great (Subaru sound!)-Butt dyno shows more power than my old DC 4-2-1 headers.-Exterior Welds look great-Adjustible Test pipe helps make install easy-Holes for Wideband-Great header for Daily Drivers or lighlty-medium modded B Series engines.- Header gets great Color after a few heat cycles.- Cleared A/C- Cleared my factory radiator fan/shroud (I Am only running the passenger side shroud on a much thicker Skunk2 Radiator)Con's:- Very Raspy (could be my exhaust set up)- Exhaust bolts could be a hair longer- Wish there was a resonated test pipe option- Pretty loud, will need a good post downpipe set up to be perfect ( opinion based )- Welds on the interior of the piping we're a little ugly. Especially from header pipe flange to the head. Would need to be smoothed out to be perfect.Final comments after having installed for awhile:-I would highly recommend doing both 02 sensors so you won't have time drop the exhaust for a long time after that. I re used mine and they're pretty old. Gave me some issues.- I would buy again and highly recommend to all my daily driver or lightly modified friends. It's great seeing people break they're neck expecting a subaru only to see a Honda. Everyone laughs and loves it. Haven't had any issues yet. I'll update my review if I notice any cracking or issues.I do have a sound clip on my Instagram: issahondaThis product was installed on my 98 DB Integra w/ B20 swap

make sure to do plenty of research before buying! i researched for a few months before splurging on this piece.having another 1320 header and custom exhaust i didnt need to use the test pipe, fitment was great. the vband once tightened all the way down and correctly has zero leaks. i feel as this is more a novelty piece, it's different and very nice for cruising. this header is probably great for a low revving non vtec b18/20 as its too restrictive while in vtec in my b18c and good buddys b16a. tldr great header if youre not trying to go fast. nice low end tq no top end. if their was such a thing it'd be a 'stance' header.Pros.it's beautifulthe rumble/soundCons.huge loss in power compared 1320 toda and rmf rep

I took a risk buying this header, and I'm sorry to say, it wasn't worth it. Straight out of the box, the header would not fit over the studs on engine (b18b1 in a 2001 Acura Integra LS). My car feels like it has an increased restriction compared to stock. The worst thing though is that no matter what you do, there will always be a leak at the v-band clamp. I tried getting a v-band clamp gasket and using a small amount of high temp rtv, but nothing worked. I can't return the header either because I already installed it. I have regrets. I should have bought the Toda Replica header. I wish I could exchange it, oh well...

Product came fast and was packaged super nicely. Easy to install if you a buddy to help hold the down pipe. All my homies are flipping out about how good it sounds!
