build my single exhaust

[brokebill]

ive searched thread after thread and cant find a defining answer since it deals with keeping single exhaust on a lopo.

i need to replace my stock single exhaust from the y pipe back. i'm going to punch out the catalytic converters (unless it makes more sense to eliminate them entirely)

to get the sweetest sound out of the single exhaust what should do? price is an issue .
should i increase pipe diameter? best muffler for single exh? etc.

im clueless on this and i know through yall's trial and error i will get it right the first time.
thanks a lot.

Too bad you're so far away from me, otherwise I would give you the single exhaust that I removed from my mom's car. You would just have to cut the muff off and replace with one of your choice.

IF you really want to stick with single... go with 2 1/2" pipes and an inexpensive chambered muffler.

In all honesty, it's worth the extra money to just go duals. Then you could run 2 1/4" pipes with a pair of inexpensive chambered mufflers.

The Summit chambered mufflers and Flowtech Afterburners are great choices for the money. Both chambered, not really loud just have a nice throaty grumble.

can i get 2 1/2 pipe already shaped to fit like the 2 inch stock? what about the catalytic converters?

If cost is an issue, just got with a strait pipe... just make sure its quality pipe thats not going to rust in a year... it wont be too loud if you keep the cats.

how much you got to spend? that is the key......there are no 2.5" pipes except maybe the impala ss tailpipe that are going to fit

[brokebill]

with the guts knocked out of the catalytic converters , what muffler would sound best if i just use the stock 2 inch pipe?
the old pipe is still useable condition.

with other needed parts and suprises really trying to watch the money and spread it to as many projects as i can , but will do what makes sense.

[85crownHPP]

you cant really gut the 1st two, the 2nd two are even hard to get to due to the bends in the pipe.
No need to focus on them, they arent holding you back unless they are clogged.

How much $ do you have to work with, and will you be doing this yourself?

i used my tire iron and rammed it in there twisting and breaking the insides out. used the tire iron to ream out both ends of the down pipe. some of the stuff is still around the edges, but main flow area is knocked out. tire iron is great for knocking the guts out. if you keep the catalytic convertors intact, they will act as mufflers and save money on having to get a muffler.

Does your car have to be inspected, or pass emissions?

If not, you could convert to dual side pipes for cheap. Then you'd have the coolness of duals, and the added performance. Terminate the existing exhaust at the end of the cats. Have a shop make you some angled bends w/ flanges (no more than $60), and bolt them onto the front pipes. You don't need mufflers if you retain the cats. It will be loud, but bearable.

Or, you could get a replacement h pipe (for duals), bolt that on, and then add turndowns, mufflers and turndowns, or whatever you want to do. Turbo mufflers are cheap, and are a nice compromise of sound and performance.

no inspection at all, not even visual. ( me and my wife joke we have the only cars in town that all the lights work)

h pipe , mufflers , and custom bent turn downs/outs depending. maybe emerging right in front of the rear wheels with nice tips. sound like a plan?

[P72Ford]

Thats a plan. Having them exit under the car sometimes results in fumes in the car... happened with my brothers '88.

Also, if I were you 'd go with turbo mufflers over glasspacks. Both are comparable in price, but the glasspacks are shitty in my opinion. Not enough sound, and the sound there is isn't flattering to the car.

[87_crown_vic]

turbos & turndowns FTW!!!!!

[brokebill]

how essential are h pipes compared to just running separate pipes right after catalytic converters? probably a dumb question but..

[murphmobile2]

If you want an upgrade while keeping it single, don't go with the 2", go with the 2 1/2". Any exhaust shop will be able to do the exhaust in that size in the factory location.

Turbo muffs are good choices, but I would highly reccomend a cheap chambered muffler. In reality the price difference is only about $10, and well worth the extra amount.

And you only need an h-pipe if you're having dual exhaust installed. Helps even out the exhaust flow, helps for a few ponies. You can't install them on single exhaust, and even if you did... it would be utterly pointless.
