Paint the muffler and exhaust with some High temp paint 1200-1500 degree exhaust paint, you muffler and exhaust will last a little longer.......and butt those tips up to the rear muffler bulkhead and tack weld it with 3 or 4 each.....

 

Yeah, the tip openings seem a little too big so they will definitely need to butt up against the muffler. Hope they won't sit too far back when it goes on the car.

 

They won't......... you'll be very satisfied!!!!!! A friend of mine addedsome 3" exhaust tips to his factory muffler and painted the muffler black with HTP and it looks like a Pacesetter performance muffler and the tips fit perfect......

 

Thanks man. That's good to hear. My muffler shop is installing it on Tuesday.

 

I did mine with 2.5" tips and I sorta regret it, since @ that time my 2.5" Cattman rear muffler was my alternate and the OEM muffler was the permanent w/the Cattman 2.5" bpipe, and the Cattman 3" tips were perfect for this car's rear valance exhaust cutout.....very sporty....kinda M3ish

 

I haven't put any tips on my bosal yet. Does anyone know the size needed. And yes some Bosal have the slanted tips and some don't. So far so good and the quality of the unit. It had a nice growl to it in the beginning but now it seems alot quieter. Maybe I am use to it or it really has grown quieter with use, either way a great value.

 

I bought the Magnaflow tips that seemed to be real popular here on this site.

Let me get mine installed and I will let you know how it went. There seems to be a lot of play between the pipe and the tip opening so I'm not sure how they will work it out.

 

am i ordering the right parts?

I need the entire catback so i'm guessing i need the center and the rear piece

http://www.autopartsway.com/autopart...ma%20SE~241069

also, do these come with any gaskets?

 

I don't see a B-Pipe listed on the site.

 

they call it the "center" piece

http://www.autopartsway.com/autopart...069~241069~110

is this the right part?

 

Here's the B-pipe:

got the catback!
first of all autopartsway ftw! Ordered the stuff yesterday and got it delivered today (free shipping)...which brings me to my complaint! The pipes were shipped as is w/o any packaging! There are a bunch of dings here and there but nothing too noticeable..

some pics...

Congrats on your purchase. That sucks about the dings.

 

Update: 5 years later and the B pipe is done. Rusted through. Bosal quality doesn't seem very good. Just ordered this today

 

Looks Nice, How much did that one run. And not bad for the other exhaust to last 5 years. Do you live in one of those snow states?...

 

That thing is puny!

 

Live in Boston so lots The muffler was 113.00 and b pipe was 70.00. All I need is about 2-3 more years and I am good. Waiting on the next Mazadspeed 3.

 

Not bad and when you get your Mazda.....Zoom Zoom...

 

wow nice 5 year update lol shoulda got stainless steel 304 it would outlast the lives of both those exhaust

 

Could you be too quick to judge? Which one is it great vaule or poor?

IMO 5 years is pretty good for an aftermarket OE replacement exhaust in the North East.

I got my napa exhaust (bosal IIRC) in 04/2010 and mine rusted through at the back of the resonator in 08/2013. I welded it back together as much as possible, 6 months later 02/2014 starting to get noisy again.

 

For muffler, you better off installing this

I guess I figured it would have lasted more than 5 years. So if you look at it I guess for what I paid for it. I was a decent value.

 

I bought my bosal when you did and it rusted through last summer. I ended up buying a Walker QuietFlow SS muffer. I am happy with my choice.

 

CMAX, what mufflers other than OEM $$ incorporate the internal variable flow flap?


i am redoing all my exhaust and afraid my bosal will be loud once I do everything else.

 

boondoxmax, what brand is that b-pipe? (edit , the sticker in the picture says Walker)

 

That's a Walker bpipe. Walker and Bosal seem to be about the same price/quality. I had a Walker muffler and bpipe at one point in time. Don't plan on them lasting long (2-3 years) but the Walker had a lifetime guarantee so even though it rotted out in 2 years I got a free new one which I promptly sold to someone else.

 

thanks for your input!

 

I'm confused. Had a Bosal muffler and was fine to me. Rusted on top, and replacement I just got from rockauto is nasty sounding...unless..

A. The crush gasket isn't sealing...but I can't see any gaps and it looks uniform.
B. Upstream popped a hole somewhere while me working on it. Maybe had a weak spot?

Under the muffler it sounds quiet. Upstream listening makes it sound like the noise is in the rear somewhere. I wrapped a rag little by little on the gasket joint and it made no difference. It's crazy. It always sounds like it's coming from somewhere else.

I know you all can't diagnose from where you are...but I am stumped.

Thoughts? Hate to send it back if not defective.

 

Found my hole. Upstream on the resonator. Both muffler and resonator pipe replaced 5yrs ago. Both went bad same time. Not much life that's for sure. Thought it would last longer.

 

nah... sounds about right... espeically in snow areas

 

Regarding Fed and Cali exhaust specs....

The Bosal resonator I have now that needs replacing is a Cali spec, something i just recently noticed when looking for a new one. At the time the parts place sold me the wrong part number I guess. It has worked and fit fine.

Rockauto has the Cali spec cheaper than Fed. Any reason why I should not repeat and buy the cheaper Cali when all I need is Fed spec?

The price difference is what tipped me off as usually it is cheaper $ for Fed spec.
Just wanting to do the cheapest route....
