I installed a Borla cat-back exhaust last fall. The system is very well built with stainless steel. The clamps are higher quality than the standard cheapos at the parts store. The install was straight forward and fairly easy. The tough part was removing the old muffler. Some cutting and grinding was needed in tight quarters.
The sound is nice, a bit more throaty, but not overwhelming. However, when you get up to 70mph on the freeway, it droans like crazy. This is very annoying and makes your ears hurt after 50 miles.
The nice chrome tip is nice as long as you keep it clean. It did not take too long in a Minnesota winter for it to look like crap.
Overall, it is a well built system, but I will look at other mfgs. for my next jeep. Also I wanted to have a stainless header, headpipe, and hi flow cat to complete the system, but to no avail on a 2004 WJ. I hope this helps those looking for a new exhaust.
Hey Dave - thanks for the review. I've been waiting to see if someone would post their honest opinion about it. It seems that there are a lot of Flowmaster and Kolak fanaticals here
'00 Laredo / 4.7 / QD / stock, stock, stock .. with brand spankin' new tires! [It's a REAL Jeep]
'98 Laredo / 4.0 I6 / 2WD (no laughing!) ... SOLD.
'96 Limited ... completely totaled and taken to the bone yard.
It has been many years since my install of the Borla system on my WJ 4.0L. Aside from the cosmetic blemish of the tip due to corrosion from constant MN winters and the system coming loose and melting the rear bumper cover to it, the structure of the system is good. I have a bit of undiagnosed OCD, so the tip kinda pisses me off and no, it will not come clean, it is pitted from salt spray. Yes, after many years after it has been installed...I would have rather have purchased a different system, just didn't get the cost vs gain benefit. I finally had a muffler shop weld some of the system together to stop the awful rattling. I have never been good at getting an exhaust system to stay where it needs to. I do suppose I could get a new tip and make it shiny again However, I rather have it coated in mud from my last trail adventure anyway. Final vote, don't waste your money, there are other systems available with similar benefits that are cheaper on the pocket book.
I just fixed another exhaust leak as the band clamps on the Borla system just don't hold worth a damn. A week later, the sound of another exhaust leak. I look over the system and find that the sheetmetal on the outlet of the muffler has torn. Of course, after searching high and low, no receipt for their million mile warranty. They want about $200 to replace the same muffler, ridiculous! So I will probably be swapping an American made Cherry Bomb muffler in soon. I did get about 6 years of service out of it before it failed. In retrospect, i would have the system fully welded initially and toss the band clamps. I would also probably go with a different mfg and not waste so much money on it.
That last photo made me reminisce! I had a Borla catback on my 1993 ZJ way, way back in the late 1990s and the muffler tore in _exactly_ the same way. I threw the entire thing in the trash and put together a custom 3" setup which was the foundation for my Kolak Exhaust. So I owe it all to Borla for the motivation

Same here. Although to be fair the hanger behind the muffler was broken and I did a lot of fast driving off road. Borla sent me a replacement system under their "million mile" warranty.
I sent this email off to Borla trying to get a response. I'm irritated I spent my hard earned cash on a product with a Million Mile Warranty and it all hinges on a receipt from 6 plus years ago. I will keep you all updated whether they come through or not. email@example.com
Sir or Ma'am,
I installed a Borla cat back exhaust on my 2004 Jeep Grand Cherokee approx. 6 years ago. The system has been flawless and sounds great...until recently. I developed what sounded like an exhaust leak. Upon inspection of the exhaust system, I was disappointed to see the rear of the muffler had a large crack partially around the outlet. I have attached a picture of the rear outlet that I mentioned. Also a pic showing it is indeed a Borla muffler as part of the cat back system.
The issue... I cannot locate the original sales receipt. I have relocated twice since it was purchased. The bottom line is that Borla offers a Million Mile Warranty. One of the selling points of the product. I need a replacement muffler for my Jeep Grand Cherokee as the exhaust leak is more than annoying. Borla should provide me a replacement per the warranty to the original purchaser.
I have several groups, forums and Facebook pages that are aware of my issue with my exhaust. A few others have voiced similar issues with the rear outlet, more or less, tearing. They have decided on other manufacturers to replace their system and wrote off Borla. I would like to report back to them that Borla stands behind their product and they will replace defective components. I will be sharing my message to you with them so they also can see if Borla will stand behind their warranty to the original purchaser. A piece of paper should not stop a company from standing behind their product. I may have returned a warranty card to Borla upon purchase, however, your website does not offer a way to check. If there is an online registration, then there should be record of that.
Please advise on whether Borla will stand behind the product I purchased?
Had a busy day, but have great news to report. My email was read this morning and I received a phone call from Borla, but missed it, returned it and missed them. Right before we left for the fair, got another call back. He asked where I originally purchased the catback and what date. I said I only have the original install instructions and cannot recall the online retailer. He says," So it may have been Borla online?" Hint hint....He says,"I just need a retailer and a date and we can warranty the system." He says," so it was in Feb of 2004? Maybe the 10th?" Sure, sounds good! He says, now that I have that information, I am going to send you a complete new system." Fricken sweet! So it was well worth pestering them and giving them a guilt trip. The guy I spoke to says it is common in the Jeep exhaust due to only one hanger in the front and one in the rear. He says even wranglers have a similar issue. So he fully admits that it is common and that he was surprised the catback lasted as long as it did! He tells me that it will arrive by fedex some time within the next week or so. He ends the conversation with, "Borla will stand behind their product 100%." I'm a happy camper with a new exhaust on the way.
