Another satisfied prochamber customer. Check Mustangworld.com. There is a good step by step install instruction with pictures. You will need to use new header bolts - sorry I don't remember the NAPA part number, and a new gasket. Do it right and you'll love it. I had 3 chamber flows in the car and liked the sound, but couldn't believe how good it sounded when I first started it up with the prochamber. If I was going to do it all over again, I'd mate it with those new 2 chamber flows. They sound great.

I havent had any problems with mine either, sorry to hear about it though. Have you tried putting any loc-tite on the bolts or something?

Yes, i dont remember what time, but on one of my gasket replacements, i used loc tite, then took the bolt back off with an air tool a few months later. I dont know if the flange is warped or something, but the passenger side has never sealed up as good as it did when i first bought it.

I think i should just weld it all together

For the loudest, best sounding exhaust get Magnapacks and a Prochamber. My friend has the flows and prochamber and he said mine is louder and he likes the sound better.
