Straight pipe exhaust

I have a 1992 eagle talon non turbo 4g63. I recently replaced the stock manifold with a stainless header. I have piping from the header to the cat. I am wanting to bypass the cat and just have straight piping all the way back. What are my options for doing so? (i.e. where to obtain piping, how to bypass cat) I'm wanting to do this without spending an obscene amount of money.

Well... You could just take it to a muffler shop and tell them what you want on it and they'll do it. Assuming that you are correct about the no emissions law where your at, they shouldn't be able to give you a problem with it then...

However... If your more of a do it yourselfer, you could pick up the piping at www.extremepsi.com and just make the exhaust yourself. I have gotten plenty of piping from them and it's pretty good quality for a decent price...

:2cents:

Will I be needing to buy an exhaust system? How would I bypass the cat?

You cut the cat off and put a straight piece of pipe in its place....then either weld the pipe onto the existing exhaust, or clamp it.

Could this be used in place of the cat?: http://www.extremepsi.com/store/customer/product.php?productid=20730&cat=256&page=1&veh=1G%20DSM

Yes, but a piece of pipe costs around $5, flanges are like $10, assembly (assuming you pay someone to do) maybe $15-$20. Still comes out a lot cheaper than buying a test pipe like that.

Geez... I was talking more of just the standard piping so you can do a whole exhaust yourself or have someone else do it that knows how to... That thing is expensive for a little piece of pipe...

True to that too. You can goto Pepboys and buy lengths of pipe for pretty cheap. I made my custom downpipe for about $10 minus the flanges. And all the pieces fit together, they slide in so you just some weld around and nice tight seal.

You could cut your stock cat off, flanges and everything, that way you just have a missing section of piping there. And we sell straight pieces of piping at advance. You just need to measure your factory piping after you cut it to get the outside diameter. Then buy a piece of straight pipe with the same inside diameter, and slip fit it in place of the missing section, then clamp or weld it on. Its not hard at all.

Ok. So all I'm wanting to do is get rid of the cat. What kind of clamps can I use that won't require any welding?

They're called exhaust clamps which can be found at any autoparts store. Advance Auto for example.

Why bother on an N/A car? All it will do is increase emissions and sound like a buzzy Honda. No real power to be had.

You may gain a little bit of power on the top end but you will loose a good bit of power in the low to mid range.

Lol, I cut the cat off my civic. I didnt do it for performance reasons. I did it because I needed $100, and plus I wanted to make it sound ricier

lol and ill bet you succeeded

Did!

I thought cutting off the cat would open up the exhaust a substantial amount and give me better fuel economy?

Only on a turbo car. On a NA car you want to leave the cat on.

oh ok. thanks for the info.

i removed my NA cat after adding a header and performance muffler....
noticed more on top end, but significant loss of low end. and its a bitch to drive in the winter when you cant roll down the windows... the loudness gives most people a headache if they ride with...
