Well, the local sports car club I belong two has recents purchased a '87 TII for a club car. It needs quite a few things, most important of all is a new exhaust(plugged cats). I have a Racing Beat system on my car, and I love it, but we'd rather get something cheaper sense we're on a budget. Anybody have any recommendations? We want something 2.5-3.5 inches, no cats, dual or single tips(whichever is better) and something $500-700. Any idea's? Thanks everyone!

 

Get the RB DP/Presilencer combo, Part Number: 16207 for $245.00 and the A'PEXi N1 for about $400-$450. I have that on the Project 86 TII and it is great.

 

if you want cheap. just buy the RB downpipe and have a local shop weld you a pipe with a muffler to the back.

 

My 88 T2 just got the Bonez DP ($95ish) Bonez MP $60, single pipe back to a Racing A SS muffler ($100) Custum piping was $125, Runs great, lighter than stock or other systems and yes...CHEAP!

 

Just wondering... if you wanted to make a good exhaust system that is *emissions legal,* what would you have to do? I'm planning on buying a TII, and I'd love to do some basic intake/exhaust mods. But I'm in New York, and I don't feel like ripping it off for testing or trying to bribe the testers. Is it just a matter of putting in a high-flow cat? Can you still strip out all 3 stock cats and replace it with one high-flow one? Are there any relatively inexpensive ways to go?

Thanks! I tried searching on this, but just about everything I came up with is for people who don't care about emissions...

 

Well, there are 2 cats, not 3. If you get a downpipe, it will eliminate the first one, also called the pre-cat. You can buy a high flow one to replace the second one, also called the main cat. Now if you decide to do this, You will have to make sure your car is warmed thourghly before you get it tested. The main reason is that the precat reduces you emissions for about the first 15 minutes of driving. After that the main cat takes over.

 

OK, cool, I must have been thinking of the FD (it has 3 cats, doesn't it?). Anyhoo, are there any tests out there comparing a high flow cat with a mid-pipe/straight pipe (or whatever it's called)?

I mean, how much HP would you really lose by having the cat in there? Also, does anyone have the link to the comparison of several intake/air filter packages? I remember it coming up on the forum sometime, and I forgot to bookmark it. It tested both filtering efficiency and HP gains, I think it may have been copied from a magazine.

Thanks!

 

get your local exhuast shop to make a 2.5 or 3 inch single exhuast system up for it with one muffler. it's that easy, well it would be if you had exhuast shops that could do that kinda thing in the US.

 

Thanks everyone. I think we have a pretty good idea of what we're going to do now. I never realised how much more expesive a system is that is emissions legal! Good thing its a track car!
