I'm going to be making a custom 2.5" downpipe and custom 2.5" exhaust for my miata which will probably be in 3 pieces total. What do you guys use for exhaust flanges?

I know there are some types of exhaust matings that are just 2 flat flanges with a gasket in the middle and some use donuts or whatever. What's best and where would I get some?

 

i just use the 2flat flanges (3bolt) with a flat gasket. if you do a good job lining up your exhaust peices it works fine and is cheap. i got 3" 3bolt flanges for 4 bucks a peice and 4$ for the gasket. i got them from full-race.com

If you need more junk like a muffler or whatever, look at summitracing.com

The flanges I got were $3.5 per ($7/pair) in 3" 3-bolt. Otherwise you could get some steel plate for almost as much, dick around with a 2.5" hole saw (fun fun), and have just what you want. In these instances, I'm willing to pay to get the right part.

 

thanks for the tip. Im definitely hitting up summit for the exhaust parts. Probably going with a Summit-special round-muffler and a Thrush turbo muffler. Should be quiet

 

turbo muffler is classic. Cheap too

 

Thrush FTW

 

Now that I work at Napa I just source ---- through them. Before though I went to Summit for my exhaust.

 

you think?

 

Hell yeah. Who else gives bumper stickers with their mufflers and look cool at the same time? hmmmm could it be ...............THRUSH?
