Flowtech 50251FLT Red Hots Glasspack

The media could not be loaded. Alright so this is the long/short of it. I was also confused about “choosing a size” and this is what worked for me. I searched through a specific vehicle in my Amazon Garage and received the correct size (hope that helps). I’d not of you have after market non-oem the size may be different but auto parts stores sell various adapter cheap. I installed this on my 1987 4Runner 22re efi. Sounds pretty deep and louder than stock setup (ignore my power steering pump). I gave 5 stars for fit and ease. My SINGLE complaint is if you are not welding the ends of the flow tech do no have cut outs for clamping down on the pipe. It’s solid. I got around this by cutting my own 2 inch slits (3 of them) to allow me to clamp down and crush the flow tech to the pipe to create a seal. My experience is if there are no slits when clamping the end warps compromising the seal. Price and quality are pretty good. No complaints so far.

I did not want to alter the factory flange connection from the Cadillac converter. I cut the flange off the old muffler and welded to the new one. Was not necessary but I can unbolt easy now. For someone that does not have access to a welder or know how my gonna difficult install. Not me I’m a real man I know how to do things and I have lots of toys.

Like the price, and initial look of it but it is painted not powder coated it will easily scrath. Easy to install if you're going to use clamps. As far as sound it's great for the price. It made my 6v comuter sound like my (work truck V8 at idle) once it reaches 3500 rpms it sounds like a ricer on steroids. Also doesn't have the crackle and pop sounds your expect from a glasspack. But it's still better than the rusted through stock muffler.

Easy install on my 2001 Jeep Cherokee sport 4.0 4dr Awd, California emissions. Cut the flange off the old muffler and welded it on to the glasspack. Not quite as loud as I expected but I’m sure the neighbors would prefer this. I’m also still running the factory cats, so I’m sure without Cali emissions it’s louder.

Bought this flowtech red hot glasspack for my 2000 xj 4.0l. cut the resonator out and welded new pipe and the red hot glasspack into the factory exhaust. Sounds pretty good for being under $20. With the extra pipe I was still under $30 since I welded it in myself. Yes the paint burns off but I don't care about that. The price is cheap so why care about the paint on it.

sounds good. very little packing inside so it doesn’t require a long time to break it in for a nice sound. half the price of a cherry bomb and sounds better out of the box. i know there’s little packing inside the glasspack because i had to cut it open and shorten it to make a custom exhaust. i would definitely buy again.

Deep tone, floor it and it sounds almost like open headers.

It came with the paint chipped all over but still sounded good.
