Default MRT vs. Brullen vs. Stromung

i was wondering, what does everybody think about the MRT cat-back? i have the MRT header-back system, and i love that the MRT muffler looks so stock and sounds great. i've never heard the stromung, but heard a brullen this summer and liked it. are teh stromungs really that great with the MRT header set-up? what type of gains are really expected? i'm weary to believe what the vendors say, i wanna know what you guys say. basically i'm asking, should i ditch my MRT cat-back for a stromung or brullen? will i really see a power difference? or just sound? thank you.

With the MRT header back, the location of where the catback bolts up is moved, so a stromung or brullen catback will not mount up.

However, any muffler that fits the stock MUFFLER location will work, which the Stromung does. Not sure about the Brullen.

So basically, that means just buy a muffler and not the midpipe too.

The Brullen has the stock flange for the midpipe to the cat, but the muffler flange is totally different than stock. So it looks like your only option if you want to keep the headers is the Stromung which has questionable quality.

also i should note that of the people i've heard who have had quality issues with the Stromung, it has been with the mild steel version. Any muffler made of mild steel would yield the same problems.

I have a SS and no problems so far. Argubely gives the largest gains....Brullen is very similiar

when i took off my muffler i realized that the pipe comes in at an offset and is directed in an S shape inside the muffler instead of straight through. i changed mine to a magnaflow 3" straight through muffler with retaining the MRT ss turbo back set up. i gained at least 5-8 horsesfrom that.

I would think the turbo exhaust would flow to much for an NA to have proper scavenging.

Yes, where you'd want to have a 2.5" to 3" exhaust system for a turbo car, a decent N/A exhaust system is generally in the 2.25" range. The Brullen set-up is that. At least, that is what mine is. Too large of an exhaust on a N/A car and there will not be enough back pressure. Without the right pressure drop, the exhaust gasses will not flow as well.

And I'm quite happy with my Brullen system as well.

I have the Strömung cat back with the duel tip muffler on my RS and I love it. I am impressed with the power gains and I really like the way it sounds. Mine is the mild steel version and yes, it is showing some rust in a few spots and I have since taken the system off, wire brushed it, hit it with some rust killer and then painted it and am still very happy. With the Strömung I have yet to experience any fitment issues.

ychan - our cat-backs start at the same factory cat location, but our rear sections end at difference places to maximize fluid bends. If you want to run our cat-back, you'll have to cut off the pipe and flange it at the end of the stock location an run the whole cat-back.

You will notice a slight gain in power (v.s your current setup), as the tuned lengths are a little different and our system flows more (in cfm).

Despite that 500hpwrxsti was talking about turbo cars, I think a Magnaflow muffler matted to the MRT system would be excellent. (Just a 2.5 or 2.25 single or dual tip muffler, not one of the giganto ones)

Local muffler shops carry them, kinda like flowmaster. You can walk in and point at one on the wall and say "I want that one!" if you want

Yup, then you and the guy driving the 1985 mustang down the road can have matching mufflers! JK, Magnaflows are great mufflers.

I believe they are, yes.

BTW: For those of you who got a magnaflow, what size did you get? 5"X8"? Round or oval? Just curious.
