Specifications

PRODUCT OVERVIEW

Hooker offers universal bolt-on turnout style Mufflers which are perfect for Jeeps, Broncos and Land Cruisers using fender well exit headers. By using a spin-ring for universal mounting, these 3" diameter case sidemount Mufflers will bolt to any 3-bolt 3" diameter collectors. We supply mounting hardware for proper muffler support. The Mufflers use a welded all metal core for longer life and are engineered to control sound without restricting flow. Hooker polishes chrome Mufflers before and after welding to insure a perfect finish. Sold as a pair.

Really nice product

I really like these Universal turnout header muffler. The chrome is good quality and they have a nice hanger system built into them. In my opinion they could be a bit louder but on the other hand it is nice to hear yourself think. I have had louder mufflers that get annoying on a long drive. Performance wise I have had them on my 304 and now my 401 and switching from a standard header muffler to this I didnt really notice a difference. I did notice better performance when i switched to the Hooker headers from another brand.

A big disappointment

I put these on my '78 CJ7 with the 304 V-8. I previously had glasspacks that lasted over 12 years before they burned out, and since I don't do as much mudding as in my younger days, I thought these would look good and give good performance as well. I was half right. They look fantastic--the chrome is excellent, and they look great from a distance. However, they are WAY too quiet! Even my wife commented that she thought they would be louder. I alos noticed a considerable drop in acceleration and performance. I took them off, and noticed that they are not a straight through design. Way too much back pressure. I'm buying a new set of Purple Hornies to replace these. I love the look (only reason for 2 stars), but performance and sound are a real disappointment.

4 Answered questions

Will these work with a 1977 CJ5 Renegade with a 304 V8 engine & headers? I have approximately 30" from end of header to rear wheel well. Thanks

Hello Jimbob, The Holley Performance Universal Turnout Collector Hooker Muffler will work on the CJ5. I have a set on my 78. You will just need a flange style header not a ball mount. Thanks for the inquiry.

Will these bolt up to the ball and socket type headers?

Have read some reviews on this product and they are so so one fellow said they have too much back pressure and im looking for a little bark but not too loud.You said they are straight through with muffler on the sides so they should be quiter than the glass pack purple hurbies that i have now

Asked by brad from prince george canada on

Hi Brad, These collector muffler's have a unique low tone to them. They are not as quiet as a conventional turbo muffler but not as loud as most aftermarket glass packs. Thanks for the inquiry.
