Timmmmmy Posted January 8, 2013 Posted January 8, 2013 I'm going to be putting in new exhaust shortly and I have a few options. A friend of mine is going to fab me the pipes out of stainless, depending on the condition of the cat I may or may not keep it in. Eventually I would like to put a cold air intake in and possibly headers, just not at the moment due to cash limitations. My buddy said to search around and let him know what I'm looking for. He suggested either a magnaflow or a flowmaster for the muffler. I listened to both online and am leaning towards the Magnaflow. I don't want a really loud exhaust system, just needs to sound quality. The magnaflow had a nice deep rumble to it, sounded nice. So assuming you were looking to for quieter, quality exhaust system that wouldn't break the bank, what would you go with? Muffler, Cat, and what diameter pipe would you go with? Any tips or special comanche considerations would be most appreciated. Thanks.
tubpilot Posted January 8, 2013 Posted January 8, 2013 I have a 40 series Flowmaster, no cat and a Pacesetter header (only one made for Renix I think) and it's not too loud. The pipe exits in front of the rear wheel, so there is only one bend in the system, and it's all 2 1/4". A friend put the same system on a Grand Cherokee and had to add a hi flow cat to shut it up, seems it was louder cause the muffler is under the body not the bed.
Lee21490 Posted January 9, 2013 Posted January 9, 2013 Magnaflow cat -> 40 series flowmaster here Sounds great Imo. Can barely hear it while driving, Does get loud if you get up in the rpm's though.
Timmmmmy Posted January 9, 2013 Author Posted January 9, 2013 Alright guy's thanks for the input. The internet consensus seems to be flowmaster 40 series muffler for cherokee/comanche. Flowmasters definitely sound nice, just thought it might be a little loud for my liking. I think a good cat might quieten it up a little. Ill look into thrush welding, new to me.
Dadinator Posted January 9, 2013 Posted January 9, 2013 Have a flowmaster on mine. Don't know the model. Pulled it off of my donor. (Free Muffler :yes: ) Cat has been gutted years ago. Sounds good. Not loud at all.
shelbyluvv Posted January 9, 2013 Posted January 9, 2013 It is not Thrush Welding. Thrush makes a knock off Flowmaster that is about $30. They do not have the drone that the Flows produce. I have been running them for years on all my Jeeps. I made the mistake of putting a Flowmaster Deltaflow 40 on my WJ and it is stupid loud and drones inside bad. As soon as it rots off it will be replaced by a Thrush Welded. http://www.thrushexhaust.com/pdf/thrush.pdf
HOrnbrod Posted January 9, 2013 Posted January 9, 2013 :agree: The Flowmaster 40 droned like he!! on mine at around 2200-2300 RPM and I didn't wait until it rotted off before junking it. Never again........
nhrocker Posted January 10, 2013 Posted January 10, 2013 I run a Dynomax Super Turbo muffler in both my XJ and MJ. I prefer the low, deep tone of them and they don't have the drone that some others are known for. Mine also has no cat, and exits through the frame rail just under the front of the bed on the passengers side and I still don't think it's too loud at all.
dasbulliwagen Posted January 10, 2013 Posted January 10, 2013 The flow master 50series adds an extra chamber and is much mellower than the 40. I have one on my 2.5 with no drone through a gutted cat and 2 1/4" tailpipe with stock manifold. A little louder than stock at idle with a nice growl under load. My 2 cents.
88MJNC Posted January 11, 2013 Posted January 11, 2013 Just put 40 flow on mine very happy with the sound
hitman72 Posted February 18, 2013 Posted February 18, 2013 does anyone know how the Napa (soundsmaster) part number 18403 sound?
