SpeedyGreeney Posted March 21, 2014 Share Posted March 21, 2014 Hey all. Looking at throwing on a different muffler for a better sound. I am ballin' on a budget but luckily I have a buddy who's been working on and welding exhaust components for years. I've searched and I haven't really found a solid/reliable answer on here. So I was just wondering what dimensions I'd be looking for. I know it's a dual in single out but not sure about the exact dimensions. I'd rather get a compatible muffler than have to deal with a y-pipe. All help is appreciated! Link to comment Share on other sites More sharing options...
SpeedyGreeney Posted March 21, 2014 Author Share Posted March 21, 2014 I'd prefer a thrush muffler as it's cheap for a decent tone... if anyone has experience with that. Link to comment Share on other sites More sharing options...
SkiBumBrian Posted March 21, 2014 Share Posted March 21, 2014 Around here I here about Borla alot. I bought a Gibson and I like the tone, much quieter than I thought it would be. Link to comment Share on other sites More sharing options...
5523Pathfinder Posted March 21, 2014 Share Posted March 21, 2014 (edited) My brother had a mangaflow installed on his 99 QX4 some years back. He doesn't have it anymore, but here is what is sounded like right after having it installed.. It was never overly loud or annoying. (Sorry, it's a old video. May have been shot with a potato) Edited March 21, 2014 by 5523Pathfinder Link to comment Share on other sites More sharing options...
Karmann Posted March 21, 2014 Share Posted March 21, 2014 (edited) I have a Magnaflow 18" and LOVE the sound. Great tone at idle and cruising around town, helped mpg a little, and let's you know who's coming when my foot's in it.

thorpe991 Posted March 21, 2014 Share Posted March 21, 2014 i went with a thrush turbo and i like the sound its not loud but has a good tone and no interior resonance im guessing you have the 3.5L motor so it might be a littler bit louder then mine since i have the 3.3L Link to comment Share on other sites More sharing options...
barnum Posted March 25, 2014 Share Posted March 25, 2014 Question here along the same lines. I have leaky exhaust - both "mid-vehicle" resonators have bad leaks, a couple welded butt-joints are leaking, and I have a pinhole leak in the muffler. I bought the cheapo $5 putty to give it a shot. Yes, I know that its not permanent and will fail again. But for $5, its worth a try. Can't knock me for that. If/when is leaks again (if the resonators) I'm going to straight pipe those and delete the resonators. I'm considering another muffler as a wishlist item. I want to keep flow velocities similar while reducing backpressure (a.k.a. similar pipe total area/less restrictive muffler). A 2.5" single pipe achieves this (4.82 sq.in. total area for stock dual inlet pipes, 4.91 sp.in. total area at the 2.5" single out), so I'll slow down in exhaust velocity but only slightly. So, to my question: has anyone found a decently cheap dual 1.75" in Y-pipe to 2.5" single out? Or has everyone gone to a shop and gotten this stuff done?

bushnut Posted March 26, 2014 Share Posted March 26, 2014 don't feel bad about the putty. my muffler is held together with mechanics wire, beer cans, and muffler tape. just waiting for the weather to warm up before tackling this job. Link to comment Share on other sites More sharing options...

Whats warmer for you? 30 above? But i can sympathize with the janked exhaust, mine just seems to be set up to return to dust... My rear resonator fell of, and now one of my down pipe its attempting to follow suit... -Kyle Link to comment Share on other sites More sharing options...

I do most of my work on the front street so ya 30C would be fine with me...the way things are going though that might not happen till July.

SpeedyGreeney Posted March 26, 2014 Author Share Posted March 26, 2014 Can anyone tell me what inlet dimensions we have? That'd be pretty helpful in my search hahaha Link to comment Share on other sites More sharing options...
barnum Posted March 26, 2014 Share Posted March 26, 2014 Any info on the Y-pipe or how you all accomodated a single in/single out muffler with the stock dual inlet pipes? Link to comment Share on other sites More sharing options...
adamzan Posted March 26, 2014 Share Posted March 26, 2014 I'm pretty sure they just used a dual in/single out muffler. They are fairly common. FWIW I used a Dynomax one on mine, can't even tell the difference from stock on the freeway but when you get on it you can hear it. Link to comment Share on other sites More sharing options...
barnum Posted March 26, 2014 Share Posted March 26, 2014 I've had a Dynomax catback before on a Cherokee. Wasn't bad. Cheap but not much low end grunt. What dual inlet diameter? 2"? Haven't seen many/any 1.75" dual inlets. Link to comment Share on other sites More sharing options...
Karmann Posted March 26, 2014 Share Posted March 26, 2014 mine sounds about that but a little bit quieter It typically quiets down once the engine's warmed up, but always has a nice, classic VQ hum at low rpms. Sounds very aggressive once I'm in the cams past 3k. Link to comment Share on other sites More sharing options...

Can anyone tell me what inlet dimensions we have? That'd be pretty helpful in my search hahaha Its small, i'm thinking like 2" (maybe even 1.75" or for you Canadians 4.445 cm), i know my Xterra friend ran 2.5, from the CAT's back. Sounds REALLY good, nice and throaty, but this is also the same guy who put a stupid throttle body spacer, so he has his wins and misses, lol -Kyle Link to comment Share on other sites More sharing options...
Sparrow Posted March 26, 2014 Share Posted March 26, 2014 Since it's a duel in single out I'm thinking of doing a true duel all the way back and just buying two catalytic converters some more piping and then two mufflers. Anyone ever done this or have any thoughts? Link to comment Share on other sites More sharing options...

Anyone ever done this or have any thoughts? Those that I have seen try it sometimes end up getting Check Engine Lights and trouble passing emmissions testing.

Sparrow Posted March 26, 2014 Share Posted March 26, 2014 We'll I already have the first problem and my state doesn't have emissions testing but I guess that idea is a no go, oh well. I wonder what make the check engine light come on.... Reduced back pressure maybe? Link to comment Share on other sites More sharing options...

Ain't it great living in the "Dirty South"? My CEL has been on for over two years now. Mine is throwing the O2 and the emissions charcoal canister code. I wish I could give you some useful input on the dimensions of my aftermarket muffler but, I picked mine off of a '96 R50 at our local scrap yard for $40 (pipe and all)! It sounds pretty nice when I throttle it without the dreaded "drone" at cruising speeds. 1 Link to comment Share on other sites More sharing options...
