    exhaust advice please.

    I have heard that headers will sometimes sacrifice low end torque in order to gain in top end. is this always the case?
    whats a good exhaust setup that will keep good low end power?

    if you go with 3" LT's you will gain low end TQ and see even more gains at high RPM. if you go with a 2 1/2" headers, you will lose some low end but make up for it in both mid range and high RPM...

    whats a good set to buy? is it better to get coated headers or to go with header wrap?

    best bang for the buck are coated Pacesetter LT's/ORY. you can get them for cheap, and are of very good quality for around $400-$500 dollars...

    if money is of no issue, Kooks, or QTP are well over $1000 (stainless steel headers)...

    are you confusing a dual exhaust with headers? and getting it backwards?

    yea i thought the bigger the header..the more low end you will lose oh Brian your going crazy..mrr23 give him a warning and a warning level of 40 for this complete lack of edumacation j/k. but to answer your question. no you will be fine with pacesetters or any header..just make sure you dont get huge race headers. and for your exhuast i wouldnt go bigger then 3. you will start to lose power unless you are pushing some SERIOUS!!!! power.

    You won't lose TQ with LTs, you will gain it, but since it comes on later in the powerband, you may feel like you "lost" some low-end. LTs and ORY are usually good for 20+rwhp.

    yes you can. the kooks race headers are a prime example. throw those on a stock ls1. and you want gain anything

    No low end will be lost. Coated Pacesetters are a good bang for the buck.

    no cats will flow better..since there is no cats. high flow cats are for emmison tests ..if your state does them periodically

    No cats will give you some raspiness. However that can be mitigated depending on your exhaust setup. Our custom true dual setup doesn't rasp with our bullets and no cats. One of our other project cars had a cutout with no cats and the raspiness was crazy. Some with that setup typically install some type of bullet in the intermediate pipe to cut it down some.

    Has anyone ever tried the XS-Power headers. There's a guy on ebay selling a set of coated long tube headers and coated y-pipe for around $500.00 just woundering if that is worth the money? Here the link http://cgi.ebay.com/ebaymotors/Heade...QQcmdZViewItem

    Yes, I am running those on my car. Been on my car since Oct of 2006. I bought them last summer off Ebay from SSAutoChrome for $340. they have since raised thier price obviously. I am very pleased with them...

    i ordered a Pacesetter 3" ORY and had it modified to fit...

    links in my sig will give you an idea of what those headers/ORY/SLP LM sounds like...
