Can you define what welded mufflers are? Are Flowmasters 40 series considered welded mufflers? Just trying to understand what's good to use.

Thanks,
Scott

A welded muffler is a Pypes, Flowmaster style muffler. The case is welded instead of a crimped case.

In the last year or so, Pypes came out with a welded muffler that looks stock. It has an oval case, very nice piece :aok . I have them on my HP2 Belvedere I.

4.04 Mufflers must be stock looking in design (Welded mufflers not encouraged). Maximum muffler inlet and outlet is 2.5”.

I think my dyno max super turbo are hurting me.

I would go with the Pypes mufflers and take the points hit. It is the best muffler available and looks stock.

I agree w ralph(finally)
I used to be that welded looked totally race!
But alot of them now are very neat, and oval as opposed to square with rounded edges!

I just changed from the cross flow i Had to two welded!
Didnt see more mph last week, but i think it sounds more mellow!

Definitly ditch the turbo mufflers :aok

There are some good offerings from borla too, that are oval, strait thru, and look pretty stock

Probably the best crimped style non welded muffler is these

http://www.dynomax.com/mufflers.php?muffler=ultrafloss

17283 is a common 2 1/2" configuration that works well on most cars..side in center out. They are "straight" through with perforations with some sound absorbtion material.

Thanks I had just come across the Dynomax ultra flow, which seemed to fit the bill, when I thought I'd ask. Jeff who spec my cam told me they were probalbly hurting me, but until I saw an animation of the super turbo's flow I never figured it was so much of a restriction. :bow Two 180 degree turns

I think the dynomax are great
The problem with most test results ive researched on line is......

Who's doing the test!!
Just stay away from the turbo type or the chambered!

Agreed on that video ..Thanks! I new my camber was off and nose was sky high but that tells me tons. The camber is skewed because car was 1 inch higher on pass side when aligned...when i reset rear springs so car didnt sit crooked it made the camber on driver side go in and pass side go out just from the tilt of the car! I also have way to much front travel and the driver side a arms is binding at full drop. i think it get stuck at full extension!

It doesn't look like the toe is changing that much at full drop. really packing some air under the nose. It seems to be an issue all the quick cars have.
