Tri Mill Exhaust

Its always fun to add improvements to these cars. WRT exhaust, I would recommend getting an A-1 sidewinder exhaust. Worth the few extra bucks for the increased performance and much cooler sound. Throaty on acceleration and mellow at cruising speed!

 

Here's a video for some audio reference...

 

NOTE: When video starts, click 'Gear' icon and adjust video quality to 720HD...

 

 

The A-1 sounds fine.

looking at it on line.  It looks like a single outlet pipe.  I think you need the pea shooter look.

Can you adjust the valves without removing it?

if it has a pew shooter out let, where do yo buy it?

thanks for the video

Hah... "extra few bucks..."

Depends on the muffler setup.  My muffler is packaged next to my right valve bank & I have to remove part of my exhaust to adjust the valves on the right side.  If you have no heat (and therefore no heater boxes) you have more options.

Mine is dual tip, btw, existing through the bumper risers.  The section I remove includes the pipe to the muffler and the dual pipes exiting the muffler (after y-ing) out.

Any idea where I can buy this exhaust designed for heater boxes and pea shooter exit pipes?

Did a quick search but did not see the heater box/pea shooter unit.

thanks for your help

The A-1 Performance Muffler shop is located in Santa Ana (SoCal). The owner's name is Tiger and amazingly they do not have a website (that i know of). They have distributors scattered around.

 

Here's a link to a shop for your reference! These can be had with the typical dual-exhaust tip, of whatever configuration you specify! Best of luck with your project!

Have you looked at the Vintage Speed exhaust?

 

 Nice vintage look, deeper sound, better performance, with standard access to valves and perfect fit... Not mods required.  Check out their web site, and several threads on this site.   I installed one on my 2013 VS a few weeks back. Easy install. Have been loving it.

 

 I would send you the link to my previous post, with pictures but I'm on phone... Not easy to navigate site.  Can dig it up tomorrow.

 

Cheers,

For replicas , the part number that i installed-  155-204-5200... I do have heater boxes and 1915cc engine.

 

The owner is great on email, and will build you anything you need... Just tell him you have a speedster, no heater boxes, a VS, and the size engine... 

 

Will try to dig up my forum post... I asked the group for guidance and they helped me answer fit, quality, and opinion Qs...

 

Cheers

An A1 Sidewinder, which I also have on my car, will set you back about $700.  A dual tip Tri-Mill (like the one pictured in the first post) cost $130 from Kirk.  Tri Mills are actually made by SoCal Imports in Long Beach and you can buy one directly from them as well.  Just be sure they know you want the same one that Kirk gets from them for his Speedsters.

Thanks again gentlemen.  Lots of information .  No power gain from the Tri Mill, But a very low cost for additionsl noise.  No one spoke on its behalf.

 Maybe a little hp gain from the A-1 or the Vintage Speed?

After listening to all, leaning towards the A -1.  Really comes down to buying domestic where possible.

Have a great holiday and thanks again.

I just added the Tri Mill to my Speedster. I did several other things while under it, valve adjust etc. I really like the sound and the unit is very solid. Sound is throaty but not at all loud. Car does run better, don't know what role the TM has in that! I would recommend it to a friend.
