            Install was fairly easy, and it sounds great. Not the loudest exhaust out there, but for the price you just can’t beat it.

            Did not fit

            I bought this for my 04 mustang gt and the arc that goes around the axel was too big, almost like it was ment for a truck. But ended up buying an arc from AutoZone and using them anyways.

            Terrible

            The product requires heavy modification if your vehicle is lowered. The exhaust does not go over the axle correctly and your tips will not align properly. After cutting and welding on multiple different pieces I got the system to fit and it sounded terrible. I have no cats and the system still makes no noise. Very disappointed, you get what you paid for.

            Hard to install

            This SR Performance Cat-Back Exhaust is not easy to install. I had a shop that does exhaust all day long and they had a lot of problems installing this system. They had to do a lot of mods to make it fit and I still do not have the tips installed yet. But I will get it done. Rate by wrenches on at one out of three wrenches, it would be a five.

            Excellent Value!

            The fitment is good. The sound is very nice. Not too loud, but it's still aggressive. I installed this in the place of a set of Flowmasters that were welded into the factory pipes. Highly recommended!

            Works for my everyday driver..

            Needed to replace 18 year old mufflers on my daily driver 01 GT. Not to loud fit was good, if your doing this on a car driven in the north be per paired to replace the flange on the mid pipe it will need to be replaced... Pipe is 2 1/4 not 2 1/2. Grind off what is left of old ones most likely not much and your ready two go....

            Sounds great!

            The sound is awesome and overall it’s a good quality catback. The exhaust tip hangers that come with this kit do not work. You have to fab up new hanger to hang the tips. Other than that it’s a good system.

            SR Exhaust

            The exhaust system is descent for the price you pay. The section of pipe that goes over the axle, once install you’ll have to put some wooden blocks under the pipe then lower the car to tweak the pipes up. The two hangers for the tips I had to heat with a torch and twist it 90 degrees to make them work with the hanger kit I bought. The only thing I don’t like is the gap between the bumper and the tips.

            I have an 04 mach1 and after a cat delete it was way too loud with previous exhaust. So I bought this kit unsure of what to expect, and wow I'm very happy with the deep tone versus the crackle of my old exhaust! Sounds and fits great! Would highly recommend and buy this system again!!

            Hard to set in place

            Its a good exhaust system but the bolts, and everything that come with it are borderline useless... had to weld everything on, and even then its still wiggling and making some noise... Wondering if i should just cut the old muffler hangers off my old exhaust and weld them onto these to hold them in place better because they only come with one hangar for the entire muffler back, and the way the tips are held in with a allen key is useless. everything moves and wiggles under here. and im still trying to find solutions to stop it... im at a loss though it keeps banging around after like 15 minutes of driving... im not sure if this is due to who i took it to, but it overall is what you get for your money. should just stay stock until you get enough for something a little nicer

            It’s not a top tier kit by any means, but I love the sound it gives off, it’s classic sounding and very tasteful on the ears. I came from having SLP LM1s and I absolutely love this kit! Was a pain to install on stands so I did what I could and had an exhaust shop do the rest.

            Exhaust sounds good and fits good but the description says 3.5" tips. These are only 3" kinda disappointed. Now I have to order another set of tips separately.
