Nice and deep tone
Welded it up straight to my toyota rock crawler with a 22re no cats. It sounds nice and deep it not raspy. Easy to weld on and fitted just right where I needed since I was looking for this exact length after cutting my old muffler.

Inexpensive and a real nice add on to your jeep
This is a must have for your jeep. I have a 2004 Rubicon and i have to say it sounds bad ass. Not to loud and annoying but gives it a real nice growl. I would definitely recommend putting one of these on your jeep for sure

ID oversized by .13"
I ordered two 18135s. Supposed to be 2.25id but these were 2.38id and 2.5"od which caused an extra run for adapters. All four ends measured identical with a slide caliper and my 2.25od exh. pipe was like a hot dog in a hallway. Sounds great on the 2.7t when finished though.

Loud.....loud
I bought this clearly for the price. It does not say magnaflow on it which is disappointing. But i will say this thing is loud. I made this into a 65 dollar off road exhaust instead of spending 400. It definitely changes the tone to the vechicle.

Only lasted 5 years and 10k miles
2020I guess I got five years out of it (about 10k miles).... Started making a noise like a slight whistle. I say whistle cause it reminds me of that YouTube video of Bub rub and whistle tips (look it up is you don’t know). Anywho, the “whistle” was fixed when I had it removed and replaced with a different brand.2015 review (5 stars):This thing is great. Put it on my 2004 TJ wrangler and it sounds great. Not too loud. Not too quiet. Just right...
