exhaust

Hello guys I am based in Germany and currently struggling with emission problems with my ‘94 5.0 SN95. I am not familiar with other emission checks but for us the car has to run with Lambda 0.97 - 1.03 during the emission control procedure. My first try ended because Lambda was ~1.8 - so too...

Might sound like a dumb question but what exactly is the difference between a catback exhaust vs axle back? I have ford performance mufflers on now (axle back) and I think it sounds decent. I want to move up to Borla Atak cat back. Now I know the actual mufflers will be much smaller and less...

We are putting together a 1985 Mustang GT with a new 347, 430hp, and have a question about exhaust. We are looking for something that sounds good but not loud and obnoxious, the owner is in his 60's. Has BBK shorty headers, dual exhaust with H Pipe. Thinking of the flowmaster 50 Delta?

What’s up guys, I’m trying to find 1 3/4” long tube headers that will actually fit my Fox Body with an AOD without turning my engine bay into a science experiment. I know 1 5/8” would be easier, but I’m running a 347 stroker and don’t want to choke it. Fox Setup: • 1986 Mustang 5.0 AOD • 347...

Howdy friends... a little while back I put a set of Borla S-Type axle-back mufflers on my 2008 Bullitt (new, these are > $600). Part number on this set is 11750... these fit 2005-2010 Mustang GTs. I drove less than 3K miles but decided to go back to my original 2008 Bullitt mufflers. These...

Hey everybody I’ve got a 2000 gt and I recently got a aftermarket midpipe and eshaust system installed but it’s knocking against the frame under the passenger side due to having hardly an inch of clearance. I can’t find anyone else having this issue so I’ve decided to make a post about it and...

I have a 2008 ford 4.6L mustang I bought recently. I got it off auction so I don't know anything about the vehicles mod history. From what I can tell, the owner put on Borla exhausts, cams, and a tune. The owner left his original SCT XCalibrator 2 tune installer with 2 tunes and 1 stock tune on...

Hi, I am new to the forum and I have checked as many posts as I can stand looking for something similar to help. I can not find anything that satisfies an answer to my problem so here we go. I bought a 2008 Mustang GT about a month ago... This was great but I have started to find several issues...

I recently went to have some exhaust work done to my 03 Mach 1 but the shop couldn’t bend 3inch piping for my tail pipes. And I’ve been having a hard time finding only tail pipes for new edges (I have a 3 inch x pipe with dumped magnapacks) I do not need a whole cat back only tail pipes. Does...

I am trying to mount my x pipe onto my new headers and the passenger side lower stud is giving me trouble. I just can’t get it in the hole and when I do it is just the tip where there are no threads. here’s a pic of what I am talking about: Also what is this supposed to connect to?

Just got my car restored about almost a year ago it's a 1994 mustang gt (157k miles) and all I got so far done to it was a muffler delete, short-throw shifter, and just got new 3.73 gears installed. But I am looking for the best budget-friendly exhaust system possible but also pretty good. The...

I know this is one of the more common issues with these cars, but it’s driving me absolutely crazy lately. I rebuilt my 302 about 5 years ago, using the gt40p setup. The car runs flawless when I do drive it, which is maybe once a month. Within the last 6 months though there is a noticeable...

Hi! This is my first post :) I have a 93 GT Vert. I did not pass the smog/emission test because of bad gases - lambda was 1.28 at 3000 rpm. I brought the car to a workshop in my town after I sealed some exhaust leaks. There was a big leak on the pipe that leads to the smog pump. I thought...

So i’m thinking about going cat-less on my mid pipe to wake up my cars exhaust note. I have a 2003 Mach 1, bone stock. I really want to go catless but i don’t have the money to buy a handheld tuner or go get the car tuned for the CE light issue.. is there any other way that i could get rid of...

New tires

For sale: Roush axle backs for 2011-2014 Mustangs. I had these on my 2014 GT for about five years, approximately 60k miles. As you can see from the pics, they could use a little bit of TLC but I haven’t had any issues as far as leaks and they sound great. Getting rid of them because I want to go...

Got a few parts I don't need anymore. I was going to use some of these on my 2014 GT but am focusing more on my Fox Body Project so I'm trying to get rid of some of these parts that are just sitting in my garage. The axle backs are an unknown brand, possibly a custom job with some sort of...

I just finished my exhaust: BBK Shorty Headers BBK O/R X-Pipe Pypes M-80 Mufflers Quad Tips I'm not looking for opinions, I can't afford long tubes and my stock manifolds broke. I'm trying to figure out what is making the noise that sounds like its humps, it burps or just trying to stay idle...

I’m replacing my cats with an off road x pipe. My question is what type of tuner do I need to keep my CEL off when I remove my o2 sensors? Thanks

Have a 2013 Mustang GT looking to purchase headers this week. To my understanding Only certain headers will fit my X Pipe , I don’t know what brand the x pipe is and can’t figure it out are their any headers that are universal? Looking at BBK but if this is the case before I spend $5-600 on...
