Best Muffler and increasing horsepower

What Kind of Performance muffler will be best on my 91 2.0 non-turbo eclipse and Is there anything i can do to increase horsepower without spending a dime like a little tweak or something?

"Is there anything i can do to increase horsepower without spending a dime"

I wish ;)

And any high flow muffler will do. Changing your muffler alone won't affect horsepower significantly, so...

Oh, and please don't get a giant tin can.

lol no those huge mufflers are just ugly i dont know why people put those on there cars it ruins everything i just want an average size muffler something that looks good sounds good

Personally I am a fan of dual tipped mufflers. But it's just cosmetics, is all.

HKS titanium cat-back....check it out...

Oh yeah. If you really wanted performance, upgrade the entire exhaust; from downpipe to muffler. Or sections of it. But we're talking about $$ (+$500) here, and I made the assumption that you didn't have that much to spend.

he said in his first post that he had a 2.0 liter N/A. so he would need a header a race pipe to eliminate the cat and cat back exhaust.;)

you can go to an exaust shop and get a custom exaust welded up and bent for really cheap. i got mine for like >200 test-pipe back with a muffler. it's cheap and will function well for a n/t.
