Winters here, Time for bolt ons. Hello all, finally got the miss fire taken care of after replacing sparkplugs and finding a couple cracked plugs, cleaning the maf etc. and now that winter is right around the corner im going to start doing some simple bolt ons like LT headers and ofy pipe, and an intake (maybe) and idk what else. Any suggestions? I also have a couple questions about LT headers. Are there any benefits from keeping the AIR and EGR stuff? I know it would need to be tuned out if i took it out (planning on getting the car dyno tuned after i do all the mods) but are the gains affected with or without it? car is a 99 Camaro ss M6 with a k&n cold air intake and a flowmaster muffler, tick master clutch master cylinder, umi 3 point subframe connectors and a shock tower brace.

Delete AIR
1-7/8 headers, not 1-3/4
Ported fast 92 or 102, TB, 85 mm truck maf and matching CAI
X Pipe duals if you don't mind a little noise.
Tune with 6600 rpm rev limit
Ditch the shock tower brace
3.90 gears and a 26" tire
Better clutch if you want to get sassy.

HA! Yeah, thats one of the things im gonna get rid of. It sounds funny in the upper rpms, and something inside sounds like its blown apart with all that flame throwing i had going on. And i want to kick the person that did the exhaust work in the nuts. (They did a cat delete) and some of the joints are welded and some of them are clamped. The welds look like someone did it with their feet, theres holes all in it, the clampes are bent and come loose every once in a while, they didnt use factory brackets to hold the muffler so it bounces around in their home made brackets and doesnt sound right. Its a mess. Slowly fixing all the little things. What are the benifits of an underdrive pully?

Budget depends on how well the business does this winter haha. My goal is to do a few simple bolt ons and a good tune. Id be happy with 350 rwhp. I read that 1 7/8 headers are "too big" for a stock cam, and don't show any gains over 1 3/4?

1 7/8 will breathe on top and 1 3/4 will but not as much. I have bolt ons with 1 7/8 and true duels and my power line is a solid 340 wheel for 800RPM
Guys with 1 3/4 drop down after 5,500 from what I have seen but they also don't have true duels
01 02 cars have truck cams, this could also be the reason but unfortunately i don't know

Mine is the blue on blue I have a 2000 camaro with ls6 intake, slip lid and bellow with filter, 1 7/8 speed engineering into catless custom true duels
I found another car on this website that posted his 2002 with bolt ons
Look at his peak and mine

Why ditch the strut tower brace? I agree with the 1 7/8 LT's, I'll be doing the same thing over winter along with true duals. 3.90's over 3.73's?

I'm doing the same with my car. Trying to get all my bolt ons out the way.
Here's a list of my bolt ons
Ls6 intake
Ported 78mm tb
Tb bypass
Emissions deletion
Volant ram air intake with smooth bellows
Speed engineering 1 7/8 headers
Atlantic coast converters billet9.5" 3800-4000 with lockup
Under drive pulley
Things I want over the winter if money allows
Fast 90 or 92 with matching tb
Off road y pipe with a 3.5" or 4" cutout
On3performance catback
And that's all I can think of at the moment. It might be a few bolt ons I'm forgetting.

Cam will give you 40-50 wheel hp and be the best mod for the buck after longtubes
Not that it will on other cars but my fully bolt-on 98 engine picked up 5whp with 1 7/8 from 1 3/4 LT's. Bolt-on ET time in my sig.. Get the 1 7/8 longtubes and don't look back. You will not be disappointed and in the event you do any internal mods in the future you will already have them. Just my .02
