Ive been doing a lot of thinking about what I want to do to my X. Do you think it would be too loud if I removed the secondary cats and ran into a dual in dual out flowmaster original 40 into a Y pipe into the stock tail pipe? Seems really quick and easy to do

thanks, pobably what im going to do, but with a Y into a single in/out so i can use a louder muffler

Thanks for the help, one last question... if I wanted to run a single 2.5 inch out the back with a flowmaster super 40 series single in/out, would I still get a nice sound that is noticeable... also would a Y pipe between the cats and muffler disturb airflow or decrease sound... Thanks, Tim

also, do you think that with all the cats and a flowmaster 40 series delta flow, it will still have that chambered sound, just quieter?

Yeah, ive put about 8k on it in 6-7 months or so. So do you think it will pass emissions with the secondary cats removed

My car was daily driven from 99 to 05. In 05 my granddad took it to Florida as his vacation car. It sat in a garage 9 months out of the year and was daily driven the other 3 from 05 to 17. When we brought it back up, it failed the first emissions test, but after a few hours of driving it passed...

Right now I have a really bad exhaust leak from the muffler. Im 17 and still want it to pass emissions, but if im gonna buy a new muffler and tail pipe, i wanna do it right the first time

Would it be and issue to run dual 2.5 inch exhaust out of a dual in/out muffler with the cats, then later if i want, remove the secondary cats and just put a pipe to connect the front cats to the muffler?

Do you think removing the secondary cats it will still pass inspection that way ( just rule out the sound )

So would you recommend a dual inlet/outlet muffler or two separate mufflers. Also, do you have any idea about muffler silencers. In my neighborhood we have really strict noise complaint people and regulations. I really don't care about the "laws", i just have a few neighbors I like. Any idea on...

Last year I got my first car for Christmas.. a 1999 X Limited AWD 5.0L 302. Beautiful car with only 77k on it, from Florida, and has been in a garage all its life... so far I have put E3 plus, Taylor High performance wires, K&N air intake, and a throttle cable mod to it. Well this year I finally...

Hi, Im new to the site and I have a 99 X Limited AWD with the 5.0L 302 V8. Ive been looking around and cannot seem to find an answer. I would like to keep all the cats and make a custom cat-back exhaust. From the cats is a dual 2.5" exhaust, and I was wondering what mufflers you guys would...
